Testing the GC!

Today was testing the gas chromatography method to determine concentration of sulfide in water samples from our lakes!

So far, we are having some trouble with water vapor messing with the coils- so next time, we are going to increase the column temperature!

Hopefully, we’ll get our method to work well and get some values before the end of the summer, so we can start figuring out where the sulfide/sulfate is in our water system!
