Measure sulfide in industrial waste water
SULFIDE
The colorimetric analysis of sulfide uses N,Ndimethyl
para-phenylene-diamine oxalate as a
color forming reagent, best for concentration
ranges below 5 ppm with a normal range of 0 to
2 ppm.
Tytronics supports the colorimetric method
with the Tytronics'® Sentinel.
TYTRONICS'® SENTINEL
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 optics are designed with a dual wavelength
configuration; use of a reference wavelength
corrects for sample turbidity and coating on the
dipping colorimetric probe.
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
