Measurement of C1-C5 with carbon dioxide for oil & gas exploration.

by MOCON - Baseline     based in Lyons, COLORADO (USA)

The PetroAlert Model 8900 combines the selectivity of gas chromatography with the sensitivity, broad dynamic range, and hydrocarbon selectivity of a flame ionization detector (FID) providing fast analysis of C1-C5 hydrocarbons and Carbon Dioxide required in Mud Logging for Oil & Gas exploration. The PetroAlert Model 8900 uses a dual column configuration with timed backflush to vent which is used to strip off moisture and C6+ hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed sample volume is carried to the pre-cut column. Backflush of the pre-cut column is timed from sample injection so that only C1-C5 hydrocarbons are eluted from the pre-cut column to the analytical column. C6+ hydrocarbons on the pre-cut column are then vented. Then a third column is used in conjunction with a second 10-port valve for individual analysis of methane. C1-C5 hydrocarbons are separated on the analytical column and elute to the flame ionization detector (FID) for analysis.

Measurement of acetaldehyde, methanol, & benzene in CO2 applications for gas manufacturers & food & beverage industry

by MOCON - Baseline     based in Lyons, COLORADO (USA)

The BevAlert Model 8900 provides direct measurement of Acetaldehyde, Methanol, and Benzene (AMB) in Carbon Dioxide. The instrument is utilized by Specialty Gas Manufacturers and the Food and Beverage Industry to monitor trace impurities in CO2 used in carbonated beverages. The BevAlert Model 8900 employs a photoionization detector (PID). The AMB 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 AMB and other similar compounds continue on to the analytical column. Contaminants are then backflushed to vent. Acetaldehyde, Methanol, and Benzene are separated from potentially interfering components on the analytical column and elute to the detector for analysis.

Gas detection for the steel industry

by Crowcon Detection Instruments Ltd - a Halma company     based in Milton Park, UNITED KINGDOM

Regarded by many as providing the backbone to modern society, the steel industry is one which continues to evolve. Whether it is geographic shifts in demand or production, or challenges brought by energy or raw material costs, companies continue to develop their processes and facilities to meet them. Alongside these changes companies have also realised the requirement to minimise downtime due to unplanned maintenance and protect workers from exposure to toxic or flammable gas hazards.
