[labnetwork] Handheld Hydrogen and Hydride (Phosphine, Germane, diborane, silane) detectors

[Frank Gambino]

Hi Jim,

The unit you were using was the Matheson 5057.  This was actually made by New Cosmos for Matheson. The New Cosmos model was XP-703D.  DOD Technologies is partnered with New Cosmos.

The XP-703D was replaced by a newer version called the XP-703D-III.  The XP-703D-III like the XP-703D is a general leak detector and basically detects the flammable part for these gases.  It is strictly a qualitative and not quantitative unit.  It can read arsine down to 50ppb and H2 as low as 1ppm.

Another portable option is the XPS-7 which uses interchangeable EC sensors can read arsine down to 12ppb.  The XPS-7 provides quantitative data where the XP-703D-III does not.

A 3rd portable option is the CLPX which uses colorimetric technology (tape) and can detect arsine down to 1.6ppb.

Subject: [labnetwork] Handheld Hydrogen and Hydride (Phosphine, Germane, diborane, silane) detectors

I am looking for handheld detectors to "sniff" at VCR or swagelock joints for leaks of hydrogen and also for common hydrides (silane, germane, diborane, phosphine...).  The lab has a central system already, but I am looking for something to sniff at joints with after making connections and repressurizing.       (Yes we will Helium leak-check too, but this is as a followup with less likelihood of someone doing it wrong).

Many years (25?) we had a handheld unit for hydrides (about  7" x 3 " x 1", with a 4" long rubber sniffer port).   Probably made by Matheson but can't seem to find anything similar from them now (although I didn't look very hard).

Suggestions?

Thanks, Jim Sturm
