A previous application note (AS168) has been written which shows the determination of Organochlorine pesticides (OCPs) in water down to ppt (ng/l) levels using a GC/QTOF.
From the OCPs, Heptachlor and Heptachlor Epoxide were chosen to develop an enrichment method using Solid Phase Extraction followed by Twister™ to determine even lower detection limits down to ppt levels. Twister extraction is also known in literature as Stir Bar Sorptive Extraction (SBSE).
Many forensic toxicology service labs are facing increasing casework, often times with reduced staff numbers. While there is significant pressure on the lab analysts to reduce case turnaround times (TATs), it is essential that the results are reproducible and reliable for consideration as evidence in a Court of Law.
