Low Level 1,2,3-Trichloropropane Determination by Purge and Trap


1,2,3-Trichloropropane (1,2,3-TCP) is usually found at industrial waste sites. It can be used as a solvent or as a degreasing agent and is also a chemical intermediate when synthesizing other compounds. 1,2,3-TCP does not typically leach into soil, thus it is commonly found in ground water. Since it is a highly carcinogenic chemical and has been found to be a common contaminant in ground water, California has established 1,2,3-TCP as a hazardous compound with a notification level of 0.005-micrograms per liter (μg/L) in drinking water. While in Europe, 1,2,3- TCP is listed as a substance of very high concern that may cause cancer and is toxic for reproduction. This application will examine purge and trap sampling in conjunction with Gas Chromatography/Mass Spectrometry (GC/MS) for the determination of low levels of 1,2,3-Trichloropropane.

Our Impact

EST Analytical has been helping labs achieve their analytical goals for over 30 years. Our vision is to engineer reliable laboratory instruments that enable partners to make the world a better place.

To help labs excel we offer Application Notes across our entire product line. They are a resource that explains the technology, performance, and abilities of our products as used against certain methodologies and or applications.

Whether your needs center around a USEPA method, an ASTM Standard, or a sample matrix-based outcome EST has you covered. If you don’t see the technical direction you need, simply contact us. We also offer sample analysis in our onsite Applications Lab.
