Vacuum Distillation is a new US EPA developed sample preparation/GC/MS technique. This new technique was developed as an alternate & improved method for the detection of Volatile Organic Chemicals (VOCs) from most environmental samples. The US EPA promulgated Methods associated with this technique are:

The Vacuum Distillation Technique was developed by the US EPA specifically to overcome matrix effects from a wide range of sample matrices.
  • This new Vacuum Distillation technique addresses most of the deficiencies that have long plagued the existing VOC techniques.
  • Unlike Purge & Trap and Head Space techniques, Vacuum Distillation has a theoretical basis. The analyte recoveries using Vacuum Distillation are based on the boiling points and partition coefficients of analytes being extracted.
  • Vacuum Distillation is much more accurate than traditional Purge & Trap or Head Space methods of extraction, and has the advantage of being much simpler and more reliable.
  • Each and every sample test has built in quality control features that provide a level of confidence not available by Purge and Trap or Head Space techniques.
  • All VOCs, some polar and some SVOCs with boiling points below 245C and partition coefficients below 15,000 can be extracted efficiently from sample matrices.
