The Hanna Instruments 93705-03 silica reagent, for use with the
HI 96705 Silica Portable Photometer, contains the proper dosage
for 300 tests that measure the silica content using the LR
heterophony blue method in water samples in the 0.00 to 2.00 mg/L
range. HI 93705-03 contains three reagents; three bottles of an
odorless, clear liquid reagent, 300 packets of an odorless, white
powder, and 300 packets of a slightly pungent, white powder
required for the three-step process.

A reaction between the reagents and silica in a sample causes a
distinct blue color to appear, which is measured by the
photometer. The photometer uses an adaptation of the ASTM D859
method of the heteropoly blue method.

Reagents are used in photometers to measure the light intensity
of solutions or surfaces. The reagent is mixed with the sample
and placed in the photometer, which then produces a reading.
Reagents are commonly used in the water quality, agricultural,
and horticultural industries to measure the amount of minerals
and chemicals in water samples.
