Color in potable water
COLOR IN POTABLE WATER
Color of incoming raw water is used as a
control parameter for proper operation of a
water treatment plant. Tytronics'® Sentinel
measures "apparent color" utilizing a direct
spectrophotometric method. "Apparent
color" includes not only color due to
substances in solution, but also that due to
suspended matter.
METHOD
A direct spectrophotometric method is used
to measure "apparent color". The
instrument monitors two wavelengths,
measurement wavelength of 450nm and a
reference wavelength of 810nm. Pathlength
of the measurement cell is 4 cm.
TYTRONICS ANALYZERS:
Provide continuous on-line analysis of
water or wastewater stream;
Include self-checking for easy diagnostics;
Minimize sampling requirements.;
Have multiple communication ports,
including bi-directional RS 232.
The optics are designed with a dual
wavelength configuration; use of a
reference wavelength corrects for sample
turbidity and coating on the dipping
colorimetric probe.
TYTRONICS'® SENTINEL
The Tytronics'® Sentinel is an on-line
colorimetric analyzer, using a batch
sampling technique that allows the use of
0.25" tubing for sample and reagent lines,
so small amounts of solids will not affect
instrument performance. A Kynar cyclone
filter can be supplied to remove excessive
solids in the sample.
Other advantages of batch sampling are:
Analytical results are not affected by
sample and reagent flows;
Analyses are only performed as
frequently as required, minimizing
reagent consumption.
The instrument has an auto blank feature
which compensates for sample background
color. Because of these features, weekly
instrument calibration is sufficient, and
calibration is automatically performed to
insure instrument accuracy
Enhanced Features of Tytronics’
Sentinel:
Programmable from 1 to 10 methods for a
single analysis compound;
Up to 3 different calibration methods;
Eight relay outputs, multi-programmable
on each relay;
Alarm functions, including sample flow,
reagent level detection;
From 1 to 6 stream configurations
standard.
