Accurate gas testing

Mini-Lab is a benchtop quadrupole mass spectrometer system that offers detection limits of <1 ppm for most gases and down to <50 ppb for some noninterfering species. The system can even be used to measure water concentrations down to <500 ppb. This performance is made possible by a combination of optimized analyzer features, a low background vacuum system, and a low-volume, inert sample gas inlet. The gas inlet allows the sample to be taken from a stream that is regulated just above atmospheric pressure.
