We retired our MIRAN and purchased a Gasmet DX4040. We haven’t used it too much yet, but some. It has a learning curve but it has a lot of capability (direct reading and ability
to ID unknowns). PID and FID detectors can be used for most VOCs and some inorganics (PID), but of course they are not specific for any particular gas/vapor. They are all part of the tool box with different strengths and weaknesses, and applications based
on that.

Subject: [DCHAS-L] Industrial hygiene monitoring instrumentation
The MIRAN Sapphire is an instrument to monitor gas / vapor exposure in real time. Manufactured by Thermo Scientific. Unfortunately, this instrument is going to be discontinued and service support will cease in the future. I am looking into
the
Gasmet DX 4040 portable chemical gas analyzer to replace the MIRAN. Does anybody have the Gasmet DX4040 in operation? Please provide feedback. How reliable is this instrument? Are there any other portable instruments to detect hazardous vapors in real time
such as formaldehyde, isoflurane, xylene, benzene, phenol vapors, VOC in general? Any suggestions are appreciated. Draeger test tubes, diffusion badges are great but the accuracy is (+/-) 25%
Thanks in advance,
Luis.
