 STATISTICAL & TECHNICAL DEFINITIONS RELATED TO

PRODUCT SPECIFICATIONS

Method Detection Limit (MDL): “The method detection limit (MDL) is defined as the

minimum concentration of a substance that can be measured and reported with 99%
confidence that the analyte concentration is greater than zero and is determined from
analysis of a sample in a given matrix containing the analyte.”1 Note that, “As Dr. William
Horwitz once stated, ‘In almost all cases when dealing with a limit of detection or limit of
determination, the primary purpose of determining that limit is to stay away from it.’”

Accuracy: Accuracy is the nearness of a measurement to the accepted or true value.3
The accuracy can be expressed as a range, about the true value, in which a measurement
occurs (i.e. ±0.5 ppm). It can also be expressed as the % recovery of a known amount of
analyte in a determination of the analyte (i.e. 103.5 %).

Resolution: Resolution is the smallest discernible difference between any two
measurements that can be made.4 For meters this is usually how many decimal places are
displayed. (i.e. 0.01). Note that the resolution many change with concentration or range.
In some cases the resolution may be less than the smallest interval, if it is possible to
make a reading that falls between calibration marks. A word of caution, that resolution has
very little relationship to accuracy or precision. The resolution will always be less than the
accuracy or precision but it is not a statistical measure of how well a method of analysis

SMART3 Colorimeter 09.16 7

2

works. The resolution can be very, very good and the accuracy and precision can be very
bad! This is not a useful measure of the performance of a test method.

Repeatability: Repeatability is the within-run precision.5 A run is a single data set, from
set up to clean up. Generally, one run occurs on one day. However, for meter calibrations,
a single calibration is considered a single run or data set, even though it may take 2 or 3
days.

Reproducibility: Reproducibility is the between-run precision.

6

Detection Limit (DL): The detection limit (DL) for the 2020we/wi
is defined as the minimum value or concentration that can be determined by the meter,
which is greater than zero, independent of matrix, glassware, and other sample handling
sources of error. It is the detection limit for the optical system of the meter.

CHEMICAL TESTING

 WATER SAMPLING FOR CHEMICAL ANALYSIS

Taking Representative Samples

The underlying factor to be considered for any type of water sampling is whether or not the
sample is truly representative of the source. To properly collect a representative sample:

◊ Sample as frequently as possible.
◊ Collect a large sample or at least enough to conduct whatever tests are necessary.
◊ Make a composite sample for the same sampling area.
◊ Handle the sample in such a way as to prevent deterioration or contamination before

the analysis is performed.

◊ Perform analysis for dissolved gases such as dissolved oxygen, carbon dioxide, and

hydrogen sulfide immediately at the site of sampling. Samples for testing these
factors, as well as samples for pH, cannot be stored for later examination.

◊ Make a list of conditions or observations which may affect the sample. Other

considerations for taking representative samples are dependent upon the source of
the sample. Taking samples from surface waters involves different considerations
than taking samples from impounded and sub-surface waters.

Sampling of Open Water Systems

Surface waters, such as those found in streams and rivers, are usually well mixed. The
sample should be taken downstream from any tributary, industrial or sewage pollution
source. For comparison purposes samples may be taken upstream and at the source of the
pollution before mixing.

In ponds, lakes, and reservoirs with restricted flow, it is necessary to collect a number of
samples in a cross section of the body of water, and where possible composite samples
should be made to ensure representative samples.

To collect samples from surface waters, select a suitable plastic container with a tight
fitting screw cap. Rinse the container several times with the sample to be tested, then
immerse the container below the surface until it is filled to overflowing and replace the
cap. If the sample is not to be tested immediately, pour a small part of the sample out
and reseal. This will allow for any expansion. Any condition which might affect the sample
should be listed.

Sub-surface sampling is required to obtain a vertical profile of streams, lakes, ponds, and
reservoirs at specific depths. This type of sampling requires more sophisticated sampling
equipment.

For dissolved oxygen studies, or for tests requiring small sample sizes, a Water Sampler
(LaMotte Code 1060) will serve as a subsurface or in-depth sampler. This weighted device
is lowered to the sampling depth and allowed to rest at this depth for a few minutes. The
water percolates into the sample chamber displacing the air which bubbles to the surface.
When the bubbles cease to rise, the device has flushed itself approximately five times
and it may be raised to the surface for examination. The inner chamber of the sampling
device is lifted out and portions of the water sample are carefully dispensed for subsequent
chemical analysis.

10 SMART3 Colorimeter 09.16

A Snap-Plunger Water Sampler (LaMotte Code 1077) is another “in-depth” sampling
device which is designed to collect large samples which can be used for a multitude of
tests. Basically, this collection apparatus is a hollow cylinder with a spring loaded plunger
attached to each end. The device is cocked above the surface of the water and lowered to
the desired depth. A weighted messenger is sent down the calibrated line to trip the closing
mechanism and the plungers seal the sample from mixing with intermediate layers as it is
brought to the surface. A special drain outlet is provided to draw off samples for chemical
analysis.

Sampling of Closed System

To obtain representative samples from confined water systems, such as pipe lines, tanks,
vats, filters, water softeners, evaporators and condensers, different considerations are
required because of chemical changes which occur between the inlet and outlet water.
One must have a basic understanding of the type of chemical changes which occur for the
type of equipment used. Also, consideration should be given to the rate of passage and
retaining time for the process water.

Temperature changes play an important part in deciding exactly what test should be
performed. Process water should be allowed to come to room temperature, 20–25°C,
before conducting any tests.

When drawing off samples from an outlet pipe such as a tap, allow sample to run for
several minutes, rinsing the container several times before taking the final sample. Avoid
splashing and introduction of any contaminating material.

 FILTRATION

When testing natural waters that contain significant turbidity due to suspended solids and
algae, filtration is an option. Reagent systems, whether EPA, Standard Methods, LaMotte
or any others, will generally only determine dissolved constituents. Both EPA and Standard
Methods suggest filtration through a 0.45 micron filter membrane, to remove turbidity, for
the determination of dissolved constituents.** To test for total constituents, organically
bound and suspended or colloidal materials, a rigorous high temperature acid digestion is
necessary.

**LaMotte offers a filtering apparatus: syringe assembly (Code 1050) and membrane filters, 0.45 micron,
(Code 1103).

 AN INTRODUCTION TO COLORIMETRIC ANALYSIS

Most test substances in water are colorless and undetectable to the human eye. To test
for their presence we must find a way to “see” them. The Smart3 Colorimeter can be
used to measure any test substance that is itself colored or can be reacted to produce
a color. In fact a simple definition of colorimetry is “the measurement of color” and a
colorimetric method is “any technique used to evaluate an unknown color in reference to
known colors”. In a colorimetric chemical test the intensity of the color from the reaction
must be proportional to the concentration of the substance being tested. Some reactions
have limitations or variances inherent to them that may give misleading results. Many
such interferences are discussed with each particular test instruction. In the most basic
colorimetric method the reacted test sample is visually compared to a known color
standard. However, accurate and reproducible results are limited by the eyesight of the
analyst, inconsistencies in the light sources, and the fading of color standards.

SMART3 Colorimeter 09.16 11

To avoid these sources of error, a colorimeter can be used to photoelectrically measure the
amount of colored light absorbed by a colored sample in reference to a colorless sample
(blank).

White light is made up of many different colors or wavelengths of light. A colored sample
typically absorbs only one color or one band of wavelengths from the white light. Only a
small difference would be measured between white light before it passes through a colored
sample versus after it passes through a colored sample. The reason for this is that the one
color absorbed by the sample is only a small portion of the total amount of light passing
through the sample. However, if we could select only that one color or band of wavelengths
of light to which the test sample is most sensitive, we would see a large difference between
the light before it passes through the sample and after it passes through the sample.

The Smart3 Colorimeter passes one of four colored light beams through one of four
optical filters which transmits only one particular color or band of wavelengths of light
to the photodectector where it is measured. The difference in the amount of colored
light transmitted by a colored sample is a measurement of the amount of colored light
absorbed by the sample. In most colorimetric tests the amount of colored light absorbed
is directly proportional to the concentration of the test factor producing the color and
the path length through the sample. However, for some tests the amount of colored light
absorbed is inversely proportional to the concentration.

The choice of the correct wavelength for testing is important. It is interesting to note that
the wavelength that gives the most sensitivity (lower detection limit) for a test factor is the
complementary color of the test sample. For example the Nitrate-Nitrogen test produces a
pink color proportional to the nitrate-nitrogen concentration in the sample (the greater the
nitrate-nitrogen concentration, the darker the pink color). A wavelength in the green region
should be selected to analyze this sample since a pinkish-red solution absorbs mostly
green light.

 REAGENT BLANK

Some tests will provide greater accuracy if a reagent blank is determined to compensate
for any color or turbidity resulting from the reagents themselves. A reagent blank is
performed by running the test procedure on demineralized or deionized water. Use sample
water to Scan Blank. Insert the reacted reagent blank in the colorimeter chamber and
select Scan Sample. Note result of reagent blank. Perform the tests on the sample water
as described. Subtract results of reagent blank from all subsequent test results. NOTE:
Some tests require a reagent blank to be used to Scan Blank.

 COLORIMETER TUBES AND CHAMBER

The colorimeter uses one type of tube (Code 0290) for all test factors. The handling of the
tubes is of utmost importance. Tubes must be clean and free from lint, fingerprints, dried
spills and significant scratches, especially the central zone between the bottom and the
sample line.

Scratches, fingerprints and water droplets on the tube can cause stray light interference
leading to inaccurate results. Tubes that have been scratched in the light zone through
excessive use should be discarded and replaced with new ones.

Tubes should always be washed on the inside and outside with mild detergent prior to use
to remove dirt or fingerprints. The tubes should be allowed to air-dry in an inverted position
to prevent dust from entering the tubes. Dry tubes should be stored with the caps on to
prevent contamination.

12 SMART3 Colorimeter 09.16

After a tube has been filled and capped, it should be held by the cap and the outside
surface should be wiped with a clean, lint-free absorbent cloth until it is dry and smudge­free. Handling the tube only by the cap will avoid problems from fingerprints. Always set the
clean tube aside on a clean surface that will not contaminate the tube. It is imperative that
the tubes and light chamber be clean and dry. The outside of the tubes should be dried with
a clean, lint-free cloth or disposable wipe before they are placed in the meter chamber.

Tubes should be emptied and cleaned as soon as possible after reading a sample to
prevent deposition of particulates on the inside of the tubes.

Variability in the geometry of the glassware and technique is the predominate cause of
variability in results. Slight variations in wall thickness and the diameter of the tubes may
lead to slight variations in the test results. To eliminate this error the tubes should be
placed in the chamber with the same orientation each time.

Chambers which have been scratched through excessive use should be discarded and
replaced with a new one.

 METER CARE

The optical system of the Smart3 must be kept clean and dry for optimal performance. Dry
the colorimeter tubes before placing them in the chamber to avoid introducing moisture.
For best results store the instrument in a area that is dry and free from aggressive
chemical vapors.

 SELECTING AN APPROPRIATE WAVELENGTH

The most appropriate wavelength to use when creating a calibration curve is usually the
one which gives the greatest change from the lowest reacted standard concentration
to the highest reacted standard concentration. However, the absorbance of the highest
reacted standard concentration should never be greater than 2.0 absorbance units. Scan
the lowest and highest reacted standards at different wavelengths using the absorbance
mode to find the wavelength which gives the greatest change in absorbance without
exceeding 2.0 absorbance units. Use this wavelength to create a calibration curve.

Below is a list of suggested wavelengths for the color of the reacted samples. Use these as
a starting point.

Sample Color Wavelength Range

Yellow 428

Pink 525

Red 568

Green and Blue 635

 CALIBRATION

As with all pre-calibrated meters, it is highly recommended, even if not required by
regulations, that the user periodically verify the performance of the meter by running
standards with a predetermined concentration. Results outside of specification are
an indication that the meter needs to be adjusted. This can be done following the user
calibration described on page 29. If the user calibration fails to properly adjust the meter
then the meter should be returned to LaMotte Company for recalibration. (See page 74).

SMART3 Colorimeter 09.16 13

 CALIBRATION CURVES

The Smart3 Colorimeter contains tests for the LaMotte reagent systems. The first step
in using a non-LaMotte reagent system with your Smart3 Colorimeter is to create a
calibration curve for the reagent system. To create a calibration curve, prepare standard
solutions of the test factor and use the reagent system to test the standard solutions with
the Smart3 Colorimeter. Select a wavelength for the test as described above.

Plot the results (in ABS or %Transmittance) versus concentration to create a calibration
curve. The calibration curve may then be used to identify the concentration of an unknown
sample by testing the unknown, reading Absorbance or %T, and finding the corresponding
concentration from the curve. The linear range of the reagent system can be determined
and this information can be used to input a User Test into the Smart3 Colorimeter (see Edit
User Tests, page 42)

PROCEDURE

Prepare 5 or 6 standard solutions of the factor being tested. The concentration of these
standards should be evenly distributed throughout the range of the reagent system,
and should include a 0 ppm standard (distilled water). For instance, the solutions could
measure 0, 10%, 30%, 50%, 70%, and 90% of the system’s maximum range.

1. Turn on the Smart3 Colorimeter. Select the appropriate wavelength from the
absorbance mode. Be sure to select the appropriate wavelength for the color produced
by the reagent system.

2. Use the unreacted 0 ppm standard to standardize the colorimeter by using it to scan
blank.

3. Following the individual reagent system instructions, react each standard solution
beginning with 0 ppm. Continue with standards in increasing concentration. Record
the reading and the standard solution concentration on a chart. Readings can be
recorded as percent transmittance (%T) or absorbance (A).

4. Plot results on graph paper or computer using any available plotting program. If
results are as %T versus concentration, semilog graph paper must be used. Plot
the standard solution concentrations on the horizontal, linear axis, and the %T on
the vertical, logarithmic axis. If results are as absorbance versus standard solution
concentration, simple linear graph paper can be used. Plot the standard solution
concentration on the horizontal axis, and the absorbance on the vertical axis.

5. After plotting the results, draw a line, or curve, of best fit through the plotted points.
The best fit may not connect the points. There should be approximately an equal
number of points above the curve as below the curve. Some reagent systems will
produce a straight line, while others produce a curve. Many computer spreadsheet
programs can produce the curve of best fit by regression analysis of the standard
solution data.

NOTE: Only reagent systems which produce a straight line can be used for a User Test.

A sample of each type of graph appears below:

PREPARING DILUTE STANDARD SOLUTIONS

Standard solutions should be prepared to create a calibration curve. Standard solutions
can be prepared by diluting a known concentrated standard by specified amounts. A chart
or computer spreadsheet can be created to determine the proper dilutions. Use volumetric
flasks and volumetric pipets for all dilutions.

6. In Column A – Record the maximum concentration of test as determined by the range
and path length.

7. In Column B – Record the percent of the maximum concentration the standard
solution will be.

8. In Column C – Calculate the final concentration of the diluted standard solutions
by multiplying the maximum concentration (In Column A) by the % of maximum
concentration divided by 100. (C = A x B/100).

9. In Column D – Record the final volume of the diluted sample (i.e. volume of volumetric
flask).

10. In Column E – Record the concentration of the original standard.

11. In Column F – Calculate the milliliters of original standard required
(F = (C x D/E)).

 STANDARD ADDITIONS

A common method to check the accuracy and precision of a test is by standard
additions. In this method a sample is tested to determine the concentration of the test
substance. A second sample is then “spiked” by the addition of a known quantity of the
test substance. The second sample is then tested. The determined concentration of the
spiked sample should equal the concentration of the first plus the amount added with the
spike. The procedure can be repeated with larger and larger “spikes.” If the determined
concentrations do not equal the concentration of the sample plus that added with the
“spike”, then an interference may exist.

For example, a 10.0 mL water sample was determined to contain 0.3 ppm iron. To a second

10.0 mL sample, 0.1 mL of 50 ppm iron standard was added. The concentration of iron
due to the “spike” was (0.10 mL x 50 ppm)/10.0 mL = 0.50 ppm. The concentration of iron
determined in the spiked sample should be 0.3 + 0.5 = 0.8 ppm iron. (Note: any error due to
the increased volume from the “spike” is negligible).

LaMotte offers a line of calibration standards which can be used to generate calibration
curves and perform standard additions.

 SAMPLE DILUTION TECHNIQUES & VOLUMETRIC MEASUREMENTS

If a test result using the Smart3 Colorimeter gives an over range message then the the
sample must be diluted. The test should be repeated on the diluted sample to obtain
a reading which is in the concentration range for the test. (Note: This is not true for
colorimetric determination of pH.)

Example:

Measure 5 mL of the water sample into a graduated cylinder. Add demineralized water
until the cylinder is filled to the 10 mL line. The sample has been diluted by one-half, and
the dilution factor is therefore 2. Perform the test procedure, then multiply the resulting
concentration by 2 to obtain the test result.

The following table gives quick reference guidelines on dilutions of various proportions. All
dilutions are based on a 10 mL volume, so several dilutions will require small volumes of
the water sample. Graduated pipets should be used for all dilutions.

Size of Sample Deionized Water to Bring Volume to 10 mL Multiplication Factor

10 mL 0 mL 1

5 mL 5 mL 2

2.5 mL 7.5 mL 4

1 mL 9 mL 10

0.5 mL 9.5 mL 20

If volumetric glassware is not available, dilutions can be made with the colorimeter tube.
Fill the tube to the 10 mL line with the sample then transfer it to another container. Add 10
mL volumes of demineralized water to the container and mix. Transfer back 10 mL of the
diluted sample to the tube and follow the test procedure. Continue diluting and testing until
a reading, which is in the concentration range for the test, is obtained. Be sure to multiply
the concentration found by the dilution factor (the number of total 10 mL volumes used).

16 SMART3 Colorimeter 09.16

Example:

10 mL of sample is diluted with three 10 mL volumes of demineralized water; the dilution
factor is four.

 INTERFERENCES

LaMotte reagent systems are designed to minimize most common interferences. Each
individual test instruction discusses interferences unique to that test. Be aware of possible
interferences in the water being tested.

The reagent systems also contain buffers to adjust the water sample to the ideal pH for the
reaction. It is possible that the buffer capacity of the water sample may exceed the buffer
capacity of the reagent system and the ideal pH will not be obtained. If this is suspected,
measure the pH of a reacted distilled water reagent blank using a pH meter. This is the
ideal pH for the test. Measure the pH of a reacted water sample using the pH meter. If the
pH is significantly different from the ideal value, the pH of the sample should be adjusted
before testing.

Interferences due to high concentration of the substance being tested, can be overcome by
sample dilution (see page 18)

 STRAY LIGHT INTERFERENCE

When scanning samples in 16 mm tubes, such as COD, the sample chamber lid can not be
closed. The COD adapter minimizes stray light. To further reduce stray light interference, do
not scan sample in direct sunlight.

OPERATION OF THE SMART3 COLORIMETER

 OVERVIEW

The Smart3 is a portable, microprocessor controlled, direct reading colorimeter. It has a
graphical liquid crystal display and 6 button keypad. These allow the user to select options
from the menu driven software, to directly read test results or to review stored results of
previous tests in the data logger. The menus can be displayed in seven different languages.

The test library consists of over 80 LaMotte tests and 25 “User Tests”. The LaMotte tests
are precalibrated for LaMotte reagent systems.The colorimeter displays the result of these
tests directly in units of concentration. The 25 “User Tests” may be used to enter additional
calibrations. All of these tests may be arranged in any of 3 sequences. These sequences
can be modified a limitless number of times to meet changing testing needs.

The optics feature 4 different colored LEDs. Each LED has a corresponding silicon
photoiode with an integrated interference filter. The interference filters select a narrow
band of light from the corresponding LED for the colorimetric measurements. The
microporcessor automatically selects the correct LED/photodiode combination for the
test.

A USB wall adapter, USB computer connection or lithium battery powers the Smart3.
Bluetooth wireless technology allows communication between the colorimeter and the

Bluetooth Mobile Printer (Code 3-0066 only).

 SAMPLE HOLDERS

The sample chamber is designed for 25 mm round tubes. An adapter to hold 16 mm COD
tubes and 10 mm square UDV cuvettes is included. 10 cm cuvettes can be scanned only at
525 nm and 568 nm. The light path is blocked at 428 nm and 635 nm with the use of the
adapter. COD tubes can be scanned at all wavelengths.

SMART3 Colorimeter 09.16 19

Position the COD/UDV Adapter (Code 1724) so that the
notches in the adapter fit around the posts on the chamber.
Turn the adapter counterclockwise until the arrows are at
the top and bottom of the chamber and the adapter is locked
into place. Turn the adapter clockwise to unlock the adapter
and remove it from the chamber.

 THE DISPLAY & THE MENUS

The display allows menu selections to be viewed and selected. These selections instruct the
Smart3 to perform specific tasks. The menus are viewed in the display using two general
formats that are followed from one menu to the next. Each menu is a list of choices or
selections.

The display has a header line at the top and a footer line at the bottom. The header displays
the title of the current menu. The footer line displays the time and the date, the data logger
status, the bluetooth/printer status and the battery status. The menu selection window is
in the middle of the display between the header and the footer.

The menu selection window displays information in two general formats. In the first format
only menu selections are displayed. Up to 4 lines of menu selections may be displayed.
If more selections are available they can be viewed by pressing the arrow buttons

to scroll the other menu selections into the menu selection window. Think of the
menu selections as a vertical list in the display that moves up or down each time an arrow
button is pressed. Some menus in the Smart3 are looping menus. The top
and bottom menu choices are connected in a loop. Scrolling down past the bottom of the
menu will lead to the top of the menu. Scrolling up past the top of the menu will lead to the

 CALIBRATING LaMOTTE PRE-PROGRAMMED TESTS

The LaMotte Pre-Programmed Tests have been pre-calibrated. Recalibration of the pre­programmed tests by the user is not possible. However, a procedure to standardize the
calibration can be performed to obtain the most accurate readings or to meet regulatory
requirements.

The LaMotte Pre-Programmed tests are standardized with one standard solution. To
standardize over the full range of the test, the concentration of the standard should be
chosen from the high end of the range. Alternatively, if samples do not cover the full range
of the test, a standard should be chosen that is close to the concentration of the samples.

The standardization procedure should be followed as often as required by regulations and
laws for compliance monitoring.

In the example below, the Aluminum calibration will be standardized.
Prepare a standard solution to be tested. In this example, 0.30 ppm aluminum.
