Product overview
The single wavelength Pocket Colorimeter II instruments are portable
filter photometers used for testing water, treated waters, wastewater,
estuary and seawater. Refer to Figure 1. The single wavelength
models are configured at the factory to measure at a specific
wavelength.
The single wavelength models have two channels in which
measurements can be made. Until a user-prepared calibration curve is
entered, the single wavelength instruments show only a direct readout
of absorbance. To measure concentration, enter a user-prepared
calibration curve. Refer to User-entered calibration on page 21.

Measurement
Basic colorimetry
Colorimetry measures the amount of color in a clear medium, such as
a liquid, to identify the quantity of a particular substance (the analyte) in
the liquid. Typically, the concentration of the analyte is proportional to
the intensity of the color in the clear medium (solution). In most
methods, a darker color indicates a higher analyte concentration.
Absorbance (Abs) at a specific wavelength is typically used to measure
the amount of light absorbed by the solution. Absorbance (Abs) is
calculated as:
Abs = –log T or Abs = –log (IT/IO)
Where:
T = transmittance
IT = intensity of the light transmitted through the sample
IO = intensity of the light that enters the sample
Some substances, such as dyes and different metal ions, have
inherent color and can be measured without any additions. In most
cases, a chemical reaction between an indicator and the analyte is
necessary to get a colored product that can be measured.
Once the relationship between the amount of color (measured as
absorbance) and a known concentration of a sample is identified, the
instrument can be used to measure concentrations of unknown
samples. A user-entered calibration curve is used to measure the
sample concentration.
To identify the amount of color in a sample, the instrument measures
the amount of light the solution absorbs. The absorption of light is
dependent on the wavelength of the light and the color of the solution.
12 English
The combination of an LED light source and an interference filter sets
the measurement wavelength.
Select the best wavelength
The single wavelength instruments each have a different LED and
interference filter to measure at a specific wavelength.
The wavelength (color) of light used is typically selected so that it has a
maximum absorption, but other wavelengths can be selected to
minimize interferences or other factors. For the best results, select the
instrument wavelength with knowledge about the absorbance spectra
of the species of interest, as well as the spectra of other colored
species that could be in the sample. Figure 6 shows a typical
absorption spectrum.
Refer to Table 1 to select the best instrument wavelengths to use for
testing. Do not use this table for samples that have more than one
absorption region that adds to the visible color. For example, a green
solution can have a yellow and a blue absorption peak. One or the
other peak can be used for measurements if both have different
analyte concentration. Other samples can look brown because there
are several spectra that add to the visible color.

Measurement range
The measurement range of the instrument is 0 to approximately
1.50 Abs, but can be used up to a measurement range of 2.5 Abs if the
chemistry method supports that range.
If sample absorbances are more than 1.50 Abs:
1. Dilute the sample or use smaller sample cells for the best linearity
and accuracy.
2. If a smaller sample cell such as the 1-cm (10-mL) cell is used,
complete the calibration with the smaller sample cells.
Note: Absorbance increases with the increase of the sample cell pathlength.
Use a sample cell with a shorter pathlength to measure solutions with a
darker colored.
3. Monitor the calibration curve to identify the measurement range for
a specific test.
The measurement range is the concentration range in which the
deviation from linearity is within acceptable limits.
Calibration curve
Calibration curves should ideally intersect the zero intercept for
absorbance. The zero intercept is the zero concentration point on the
calibration graph. When there is no analyte in the sample, the
absorbance will be zero.
A non-zero intercept (a positive or negative absorbance measurement
at zero concentration) can occur for many reasons. Factors that can
cause a non-zero intercept include the reagent blank, pH, temperature,
interfering species or turbidity differences between the zeroing solution
(blank) and the sample.
To adjust for a non-zero intercept caused by the reagent blank,
measure the absorbance of the prepared reagent blank and then
subtract it from the measured absorbance of the prepared sample. In
English 15
an aqueous sample, add the reagents to deionized water to prepare
the reagent blank. The prepared reagent blank includes only the
amount of color that is added to the deionized water by the reagent and
not the analyte. The prepared sample includes the amount of color that
is added by the reagent and the analyte.
For some chemistries, the intensity of the color decreases as the
analyte concentration increases. These chemistries are referred to as
bleaching chemistries because the measured sample is lighter in color
than the reagent blank that was used to zero the instrument. This
instrument is able to measure bleaching (or negative) absorbance
chemistries directly. Set the instrument zero with the reagent blank (the
most highly colored solution) and then read the sample or bleached
color directly.
Single wavelength procedure
Before starting
Always measure solutions in sample cells or AccuVac® Ampules. Do not put
the instrument in the sample or pour the sample into the cell holder.
Make sure that the sample cells are clean and there are no scratches where
the light passes through them.
Make sure that there are no fingerprints or liquid on the external surface of the
sample cells or AccuVac® Ampules. Wipe with a lint-free cloth.
Rinse the sample cell and cap with the sample three times before the sample
cell is filled.
Always insert the sample cell in the correct and consistent orientation so that
the results are more repeatable and precise. Refer to Figure 7.
Install the instrument cap over the cell holder before ZERO or READ is
pushed. Refer to Figure 8.
Measure the volume of the liquid reagent accurately. Use a pipet if possible.
If the test result is over-range, dilute a fresh sample with a known volume of
deionized water and repeat the test. Multiply the result by the dilution factor.
When the test is completed, immediately empty and rinse the prepared sample
cell. Rinse the sample cell and cap three times.
16 English
Review the Safety Data Sheets (MSDS/SDS) for the chemicals that are used.
Use the recommended personal protective equipment.
Dispose of reacted solutions according to local, state and federal regulations.
Refer to the Safety Data Sheets for disposal information for unused reagents.
Refer to the environmental, health and safety staff for your facility and/or local
regulatory agencies for further disposal information.

User-entered calibration
This instrument accepts a user-prepared calibration curve. The
calibration curve can be from 0 to 2.5 absorbance. Make sure that the
calibration curve includes standard values that are less and more than
the range of interest.
The instrument range will be the same as the calibration range. For
example, when the standards that are used are 1.00, 2.00 and 4.00.
The instrument range is 1.00 to 4.00.
There are two options to enter a user calibration curve:
• Enter a calibration curve with standards—The standard solution
values are entered with the keypad and the absorbance values are
measured.
• Enter a calibration curve with the keypad—The standard solution
values and absorbance values are entered with the keypad.
Note: If the instrument is set to off or the instrument power is removed before a
user-entered calibration curve is completed, the calibration curve is not saved.
The instrument automatically switches off in user-entered calibration entry mode
after 60 minutes of no activity. User-entered calibrations are completed when the
user goes out of calibration (cal) mode or edit mode.

Most laboratory detergents are used at recommended concentrations.
Neutral detergents, such as Liquinox, are safer to use when regular
cleaning is necessary. To decrease the cleaning times, increase the
temperature or use an ultrasonic bath. To complete the cleaning, rinse
a few times with deionized water and then let the sample cell air dry.
Sample cells may also be cleaned with acid, followed by a thorough
rinse with deionized water.
Note: Always use acid to clean sample cells that were used for low-level metal
tests.
Special cleaning methods are necessary for individual procedures.
When a brush is used to clean sample cells, take extra care to avoid
scratches on the interior surfaces of the sample cells.
