Hall-PID and 502.2 method

[Chroman]

Hi everyboby, is still someone running 502.2 method on Hall PID system?

Its been about 10 years for me - we still use the PID on occasion but we let the Hall go.

By the way, for folks discussing hydrogen safety issues, I recall our Hall ELCD (OI Corp) required a 100 cc/min flow of hydrogen. I do not believe this is consumed, its essentially a 100 cc/min hydrogen leak, if I am not mistaken.

I do not ever recall any particular safety warnings regarding the hydrogen - curious. Maybe I just did not pay attention back then.
