TEST METHODS SPECIFICATIONS

 INTRODUCTION

The most common mineral forms of sulfur are iron sulfide, lead sulfide, zinc
sulfide, calcium sulfate and magnesium sulfate. In most fresh waters, the
sulfate ion is the second or third most abundant anion, being exceeded only
by bicarbonate and, in some cases, silicate. Sulfur, in the form of sulfate, is
considered an important nutrient element. Mineral springs are rich in sulfate
and feed appreciable quantities of this compound to the watershed. Acid mine
water drainage is a form of pollution which may contribute extremely large
amounts of sulfate content to natural waters. Other sources of sulfate include
waste material from pulp mills, steel mills, food processing operations and
municipal wastes. Many bacteria obtain sulfur from sulfate for the synthesis
of amino acids. In lakes and streams low in oxygen, this process of sulfate
reduction causes the production of hydrogen sulfide, with its characteristic
offensive odor. Calcium sulfate and magnesium sulfate contribute
significantly to the hardness of water. Under natural conditions, the quantities
ordinarily to be expected in lakes are between 3 and 30 parts per million.

 APPLICATION

Drinking and surface; domestic and industrial wastes.

 RANGE

0 to 100 ppm Sulfate

 METHOD

Sulfate ion is precipitated in an acid medium with barium chloride to form a
barium sulfate suspension in proportion to the amount of sulfate present.

 HANDLING & PRESERVATION

Sulfate samples may be preserved by refrigeration at 4°C up to 7 days in glass
or plastic containers without any change in concentration.

 INTERFERENCES

Suspended matter and color interference may be removed by a filtration step.
Silica in excess of 500 mg/L will interfere.

BATTERY

 BATTERY/AC OPERATION

The colorimeter may be operated on battery power, using a USB wall adapter
or USB computer connection. If using the meter as a bench top unit, use the
wall adapter if possible to extend the battery life. The meter will remain on
when the USB adapter is used.

To charge the battery with the wall adapter, plug the smaller end of the USB
cable (USB mini B connector) into the meter and the larger end of the USB
cable (USB Type A connector) into the wall adapter. Plug the wall adapter into
an AC outlet. Reinsert the USB port plug after charging.

To charge the battery from a computer, plug the smaller end of the USB cable
(USB mini B connector) into the meter and the larger end of the USB cable
(USB Type A connector) into a USB port on a computer.

The battery icon will show no bars and flash when the unit first turns on. Then
the indicator will indicate the battery status by showing 0, 1, 2, 3 or 4 bars.

It will take 5 hours to fully charge a low battery. The battery icon will flash
when the battery is charging. The battery icon will show four bars and stop
flashing when it is fully charged. The charging circuit will automatically switch
to a float charge when the battery is fully charged. The charger may remain
connected. Some computers will NOT supply power to their USB ports during
standby operation. The wall adapter will charge the unit continuously.

The battery icon will show no bars and continuously flash if the battery is
getting low but the unit will still operate normally. A “Low Battery” message on
the status bar of the display will replace the time when the battery voltage is
too low for proper operation and accuracy may be degraded. A “Shutdown Low
Batt” message on the display will appear for a few seconds before the power
is switched off when the battery is too low to operate the unit.

To extend the battery life:

• Shut down the unit with the power switch when not taking
measurements or use the power save option to have the unit
automatically turn off after 5 minutes.

• Store the unit in a cool dry place.

• Fully charge the battery before storing the unit for extended periods
of time.

• Limit backlight use. The unit consumes 3X normal power with the
backlight on. Set the backlight time option to 10 seconds, or select
“Button Control” and keep the backlight off.

 BATTERY REPLACEMENT

The lithium ion battery used in this unit should last for many years with
normal use. When it no longer powers the unit long enough to meet testing
requirements it will need to be replaced. Lithium ion batteries that are
properly charged and stored do not usually lose all capacity; they just have
less capacity after hundreds of charge cycles. This unit uses a custom battery
assembly that is only available from LaMotte Company. Battery replacement
must be performed at a LaMotte authorized repair facility. The water resistant
housing of this meter should not be opened by the user

MAINTENANCE

 CLEANING

Clean the exterior housing with a damp, lint-free cloth. Do not allow water
to enter the light chamber or any other parts of the meter. To clean the
light chamber and optics area, point a can of compressed air into the light
chamber and blow the pressurized air into the light chamber. Use a cotton
swab dampened with Windex® window cleaner to gently swab the interior of
the chamber. Do not use alcohol; it will leave a thin residue over the optics
when dry.

administration or recycling services.

GENERAL OPERATING INFORMATION

 OVERVIEW

The meter 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 LaMotte tests are precalibrated for LaMotte reagent systems.
The colorimeter displays the result of these tests directly in units of
concentration.

The optics feature a colored LED. The LED has a corresponding silicon
photoiode with an integrated interference filter. The interference filter selects
a narrow band of light from the corresponding LED for the colorimetric
measurements.

A USB wall adapter, USB computer connection or lithium battery powers the
colorimeter.

 GENERAL OPERATING INFORMATION

The operation of the colorimeter is controlled by the menu driven software
and user interface. A menu is a list of choices. This allows a selection of
various tasks for the colorieter to perform, such as scan blank and scan
sample. The keypad is used to make menu selections that are viewed on the
display.

 THE DISPLAY AND MENUS

The display allows menu selections to be viewed and selected. These
selections instruct the colorimeter 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 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 colorimeter 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 bottom of the menu.

 TUBES AND CHAMBERS

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 air­dry in an inverted position to prevent dust from entering the tubes. Dry tubes
should be stored with the caps on to prevent contamination.

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 smudge-free. 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.

 SAMPLE DILUTION TECHNIQUES

If a test result is out of the range of the meter, it must be diluted. The test
should then be repeated on the diluted sample. The following table gives quick
reference guidelines for dilutions of various proportions.

Amount of Sample Deionized Water to Bring

Final Volume to 10 mL

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

All dilutions are based on a final volume of 10 mL, so several dilutions will
require small volumes of the water sample. Graduated pipets should be
used for all dilutions. 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 and then transfer it to another container. Add 10 mL volumes of
deionized water to the container and mix. Transfer 10 mL of the diluted
sample to the colorimeter tube and follow the test procedure. Repeat the
dilution and testing procedures until the result falls within the range of the
calibration. Multiply the test result by the dilution factor. For example, if 10 mL
of the sample water is diluted with three 10 mL volumes of deionized water,
the dilution factor is four. The test result of the diluted sample should be
multiplied by four.

 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 10. If the
user calibration fails to properly adjust the meter then the meter should be
returned to LaMotte Company for recalibration. (See page 20).

 STRAY LIGHT

The colorimeter should have no problems with stray light. Make sure that the
sample compartment lid is always fully closed.
