MOCON - Baseline
based in Lyons, COLORADO (USA)
The Series 8900 provides direct measurement of methane, methanol, and ethanol for the biofuel industry. The Series 8900 GC employs a flame ionization detector (FID). The methane, methanol, and ethanol in the gas sample are physically separated using proprietary GC columns. A dual-column configuration with timed backflush to vent is used to strip off moisture and heavier gases. At sample injection, a fixed volume of sample is carried through the pre-cut column. The backflush is timed so that primarily the MME and other similar compounds continue on to the analytical column. Contaminants are then backflushed to vent. Methane, methanol, and ethanol are separated from potentially interfering components on the analytical column and elute to the detector for analysis.
