The need to measure vinyl chloride at part per trillion levels and below in the atmosphere presents a challenge for those involved with environmental monitoring. Sentex has previously reported measuring vinyl chloride in the air at 1.0 part per billion levels and above. A portable gas chromatograph equipped with a special preconcentrator was used for on-site monitoring of vinyl chloride at sub-parts per billion levels. The test was performed at a landfill adjacent to a residential area. A lap-top computer controlled the gas chromatograph`s functions including sampling, preconcentration, chromatographic parameters, and data storage. Concentrations down to .02 ppb (20 ppt) were successfully detected.
