• Measurement at Superfund sites during remediation
• Monitoring workplace exposure limits


The Series 8900 Analyzer provides direct measurement of Chloroform in ambient air. This instrument is utilized for remediation and Super Fund sites and to monitor workplace exposure limits.

The Series 8900 Analyzer for Chloroform employs a flame ionization detector (FID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A precut column is used in series with the analytical column. At sample injection, a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the Chloroform and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. The chemicals are separated from potentially interfering components on the analytical column and elute to the detector for analysis.
