times higher than thermal conductivity detector (TCD) analysis. It also permits ppm-level trace-component analysis not possible by TCD. Additionally, the BID easily detects compounds that respond poorly to flame ionization detectors (FID) with less variation in relative response between compounds. Unlike FID, which uses hydrogen, the BID-2010 Plus only uses helium as a detector gas. Therefore, it can be used in laboratories that restrict the use of FID. Its maximum operating temperature (350... (read more)
