Description:
Vacuum distillation uses a specialized apparatus. This apparatus has been developed and patented by
the EPA. Through the Federal Technology Transfer Act this invention has been made available for commercialization. Available vendors for this instrumentation are being evaluated.
Application of vacuum distillation: The use of vacuum distillation as a tool to extract analytes from a sample requires a protocol. This protocol describes conditions of its use and an evaluation of results. Two methods of operation have been devised for inclusion in RCRA's methods manual, SW-846. The first method (5032) describes the conditions to extract volatile organic compounds and analyze the extract according to a determination method, such as method 8260. Method 8261 combines methods 5032 with a determination routine that allows for a wider suite of analytes with quality controls consistent with vacuum distillation. Method 8261 combines the vacuum distillation preparation procedure with a determinative procedure. The resulting method provides results that are more advantageous of vacuum distillation technology.
