looking for grab sample methods!

[Stevie Lewis]

Hello,

I'm looking to source some information on different methods that are available for doing air grab samples. I'm specifically interested in Hydrogen Sulfide sampling. Anyone know any good resources for different methods and how you would choose between them, or for explaining how to do this? 

I've posted a question on it here: https://publiclab.org/questions/stevie/10-10-2017/what-methods-are-available-for-doing-air-grab-samples-for-hydrogen-sulfide

Best!
