Topic: Testing for Silicates in a dilute seal tank

I was wondering if anyone could suggest a method of testing for
Silicates in a dilute seal tank containing sodium chromate/chromic acid flake
which can be preformed on-site with a relatively short analysis time. As of
now, a LaMotte silicates testing kit is used but is inconsistent and does not
always match up to the silicate concentrations as seen when samples are sent
off to a lab. Any help in the matter would be greatly appreciated. Thank you.
