$BICB The mobile analyzers are offered in a small housing with enclosure of IP 55 and with an internal rechargeable battery which makes the analyzer best suitable for mobile use. With these mobile trace gas analyzers gases can be detected and identified without any enrichment directly in situ already at a very low concentration level. The analysis including sampling and identification process takes only few seconds to few minutes depending on the GC-set-up. They can operate either in manual or in automatic detection mode. The standard operation time for our mobile devices is about 8 hours.
