Chuck,

Congrats on your new meter (gotta love new toys.) I am no chemistry buff by any measure so I have no input to your questions. I'm just curious about the silicate tester. Does it test for all types of silicates (ie: sodium silicate, aluminum silicate, etc...)?? If you put silicate sand (play sand) into some water, does the meter read this?

I went to the pathology lab last night, and inquired about testing some stuff (they have some seriously high tech equipment for doing such stuff.) Unfortunately, they are busy round the clock doing important things and don't have time to test some store bought baking soda for the presence of anti-caking agents or contaminants. My intention was to do what you did, only with a $100,000 machine.
