Hello,
Does anyone use the Honeywell SPM Flex? This is a tape-based detector by which the target gas stains the tape and the intensity of the stain is read optically and is proportional to concentration. We seem to have nothing but problems with
ours with regard to false detections. I am in Cambridge, Ma and pretty sure we don’t have background arsine and fluorine.
Thanks,
Jim
