METHOD REFERENCE TABLE
HEALTH & SAFETY
The chemicals contained in the reagent kits may be hazardous if improperly handled.
Read the Material Safety Data Sheet (MSDS) before performing tests.
Safety equipment: Wear suitable eye protection and clothing when required, and follow instructions
carefully.
Reagent spills: If a reagent spill occurs, wipe up immediately and rinse with plenty of water.
If reagent contacts skin, rinse the affected area thoroughly with water. Avoid breathing released vapors.
Waste disposal: for proper disposal of reagent kits and reacted samples, refer to the Material Safety
Data Sheet (MSDS).

Pay attention to push the cuvette completely down in the holder and to align the white point on the
cap to the indexing mark on the meter.
In order to avoid reagent leaking and to obtain more accurate
measurements, close the cuvette first with the supplied HDPE plastic
stopper and then the black cap.
Each time the cuvette is used, the cap must be tightened to the same degree.
Whenever the cuvette is placed into the measurement cell, it must be dry
outside, and free of fingerprints, oil or dirt. Wipe it thoroughly with
HI 731318 or a lint-free cloth prior to insertion.
Shaking the cuvette can generate bubbles in the sample, causing higher
readings. To obtain accurate measurements, remove such bubbles by
swirling or by gently tapping the cuvette.
Do not let the reacted sample stand too long after reagent is added. For
best accuracy, respect the timings described in each specific method.
It is possible to take multiple readings in a row, but it is recommended
to take a new zero reading for each sample and to use the same cuvette
for zeroing and measurement when possible (for most precise results follow
the measurement procedures carefully).
Discard the sample immediately after the reading is taken, or the glass might become permanently
stained.
All the reaction times reported in this manual are at 25 °C (77 °F). In general, the reaction time
should be increased for temperatures lower than 20 °C (68 °F), and decreased for temperatures higher
than 25 °C (77 °F).
INTERFERENCES
In the method measurement section the most common interferences that may be present in an average
sample matrix have been reported. It may be that for a particular treatment process other compounds
do interfere with the method of analysis.
