RE AGENT STA BIL ITY AND RE PLACE MENT

Every conceivable effort is taken to ensure long shelf-life for the test
reagents. However, typical use of a field test kit keeps it exposed to
adverse conditions. Storage of wet apparatus maintains high humidity,
which is particularly harmful. Also, temperature extremes are common.
Therefore, field test kit chemicals must be checked or replaced
frequently.

For better results from the field test kit, we recommend that minimum
quantities of reagents be kept in the kit. Fresh reagents will improve the
test results. Larger quantities for replacement should be stored in a
clean, cool, dry area. Replacement of reagents in the test kit every 6
months is recommended. The test kit should be thoroughly cleaned and
dried whenever the reagents are replaced.

To order individual reagents or test kit components, use the specified
code number.

CLEAN LI NESS

All possible efforts must be made to keep the test kit clean and dry. It
should present the appearance of belonging to a careful person, while
still showing proper use. Labels must be legible. Of course,
contamination of test reagents must be avoided. Do not touch the
dropper bottle tips to anything (mixing bottle, test tube, or their
contents). If contamination is suspected, replace the reagent. Always
cover the test tube with a stopper for mixing rather than using a finger.

SE QUENCE OF ANAL Y SES

Analyses are best run if the following sequence is used. Naturally, a fresh
portion of the water sample is used for each analysis. Omit any analyses
not desired.

A. Total Sulfide
B. Total Hardness
C. Total Alkalinity
D. pH
E. Chlorine, Free and Total
F. Total Iron
G. Silica

tt

1. Fill the test tube (0106) to the 10 mL line with a fresh sample.

2. Add one *Chlorine DPD #4R Tablet (6899), cap tube, and mix to

dissolve tablet.

3. Insert Chlorine/pH Octa-Slide Bar (3490) into Octa-Slide Viewer
(1100). Match sample color with a pink color standard on the left
side of Octa-Slide Bar. Read results in ppm Total Chlorine.

IRON

1. Fill test tube (0106) to 5 mL line with sample water.

2. Add one *Total Iron TesTa b (2792). Use tablet crusher (0175) to

crush tablet. Cap and shake vigorously until dissolved.
WAIT 5 MINUTES.

3. Insert Iron/Silica Octa-Slide Bar (3491) into Octa-Slide Viewer
(1100). Match sample color with a pink iron color standard on the
left side on Octa-Slide Bar. Record results as ppm Total Iron.

SIL I CA

1. Fill the test tube (0106) to the 5 mL line with sample water.

2. Add 7 drops of *Silica Reagent #1 (4571), cap and mix by

inverting tube several times.

3. Add 6 drops of *Silica Reagent #2 (4467), cap and mix. Wait 5
minutes.

SAM PLE COL LEC TION

All samples must be collected in clean containers. Care should be
exercised to obtain a representative water sample. On all systems, allow
the water to run until it is as cool as it can get. In addition, on well
systems, allow the well pump to cycle on and off at least twice.

Select a sample source as close to the well, or incoming line, as possible.
Remove any aerator or screens from that sampling location.

For hydrogen sulfide samples, insert a short length of plastic tubing up
into the sample faucet, with the other end leading to the bottom of the
clean container. In this way, air dissipation in the sample will be
minimized.

SAM PLE MEA SURE MENT

All samples are measured in the calibrated test tubes. The test results
can be no better than the procedures used. If the water sample is not
accurately measured, the results will also be inaccurate. Always carefully
measure the sample by filling the test tube so that the bottom of the
curved surface of the liquid just touches the marked line. This is
particularly true for the hardness and alkalinity tests. Good techniques
should be developed to assure accurate measure of the sample.

Always rinse the clean sample tube first with the water to be tested.
Discard this rinse, then, measure the sample for analysis.

SAM PLE DI LU TION

Many times, the contaminant’s concentration is higher than the test
can determine. Dilution procedures are needed to reduce the
concentration within the test range. Even when the concentration is
just less than the largest value of the test, a repeat test should be run on
a diluted sample.

Dilution is readily accomplished with clean equipment and DI water.

USE OF THE OCTA-SLIDE VIEWER

The Octa-Slide Viewer should be held so
non-direct light enters through the back of the
viewer. With sample tube inserted at top, slide
the Octa-Slide bar through the viewer and match
with color standard.

DEMINERALIZER BOT TLE

The Demineralizer Bottle is a plastic bottle with a pour spout and a
special filter inside the cap. The bottle is partially filled with an ion
exchange resin containing an indicator to show when the exchange
resin has been exhausted. The indicator will change from dark
bluish-green to yellow amber at which point the resin should be
replaced.

A. IN STRUC TIONS FOR USE

1. Remove cap and fill bottle with water to be demineralized.

2. Recap, make sure spout is closed, and shake vigorously for 30

seconds.

3. Open spout, invert bottle, and gently squeeze to dispense the
demineralized water.

B. DEMINERALIZER CARE

1. Do not heat water over 100° F.

2. Keep the resin covered with water at all times.

3. Leave the bottle fairly full when storing.

3. Add 15 drops of *Sulfide Reagent A (4458WT). Cap and mix.
CAUTION: Reagent A is a strong acid solution and must be

handled with great care.

4. Add 3 drops of *Sulfide Reagent B (4459WT). Cap and mix. Wait
for 1 minute.

5. Add 12 drops of Sulfide Reagent C (4460WT). Cap and mix. A
blue color indicates sulfide.

6. Insert Sulfide Octa-Slide Bar (3414) into Octa-Slide Viewer
(1100). Match sample color with a blue color standard. Read results
in ppm Sulfide.
