The prediction of migratory patterns of both dense non-aqueous liquid phases (DNAPL) and light non-aqueous phases (LNAPL) in the environment is a complex problem associated with hydrology and the impact of liquid contaminants on water quality. These compounds have anthropogenic origins and are related to some form of industrial activity where they are often used as metal degreasing agents during fabrication, machining, or plating. At the outset, and during the lifetime of environmental remediation projects, the degree of contamination and the speed of infiltration of the contaminant plume must be ascertained. zNose® acts as a helping hand in detecting chlorinated hydrocarbons from DNAPL contaminated groundwater. This technical paper covers topics such as:
How the zNose® quantifies the chemistry of chlorinated hydrocarbons?
Chemical analysis (chromatography) process
Lab standard of TCE and PCE
- Site generated chromatograms with a TCE/PCE standard
