In this application note, a suite of neutral and list 1 pesticides in methylene chloride is evaporated using the Biotage® DryVap.
Pesticides containing many different functional groups, including sulfur and phosphorus groups, halides, nitramines, atrazines, alcohol, and carbonyl groups were efficiently concentrated for GCMS analysis.
This data indicates that the DryVap System is inert and effectively manages solvent evaporation without generating localized hot spots in the system.

The second unregulated contaminant monitoring regulation (UCMR2) program was developed to monitor US drinking water sources for currently unregulated compounds. EPA Method 527 is categorized under List 1; Assessment Monitoring in the UCMR2 program. It focuses on a wide range of semi volatile organic contaminants including pesticides that were deferred during the first UCMR, flame retardants, and pyrethroid pesticides. This application for EPA Method 527 employs SPE with analysis by gas chromatography / mass spectrometry (GC/MS).

Method 508.1 is used to determine twenty-nine chlorinated
pesticides, three herbicides, and four organohalides in
ground water, drinking water, and water in any treatment
stage. The analytes are extracted from the water using a 47
mm C18 disk. The disk is extracted on the Horizon
Technology SPE-DEX® 4790 Automated Extraction
System using Ethyl Acetate and Methylene Chloride
(DCM). The extract is then dried and concentrated using
the Horizon Technology DryVap® with DryDisk®
technology. Final analysis is by GC/ECD.

In postmortem cases, where drugs or pesticides have been used for
their poisonous properties, traditional matrices such as urine and
whole blood may be inappropriate for qualitative and quantitative
analysis. As the site of metabolism for most drugs and toxins, the
liver may provide more insight to cause of death than other bodily
This poster describes the use of ISOLUTE SLE+ supported liquid extraction columns to extract a range of drug and pesticide classes form homogenised liver using a simple, streamlined workflow.

This application note describes the extraction of a broad range of analytes from liver tissue matrix prior to GC/MS analysis using ISOLUTE® SLE+ supported liquid extraction columns.
A protocol has been developed that allows the simultaneous
extraction of various drugs of abuse classes: amphetamines, barbiturates, benzodiazepines, cocaine, ketamine, THC.
In addition to these drug panels, simultaneous extraction of carbamate, organochlorine, organophosphate, pyrethroid, and triazine pesticide classes is demonstrated.

This application note was developed for the clean-up of a non-polar solvent extract of vegetable material. The methodology is applicable to a wide range of organochlorine and organophosphorus pesticides and a number of vegetable types. The analytes are relatively non-polar, and will not be strongly retained by polar/anion exchange sorbents.

This technical note describes the use of layered SPE columns in applications where multiple suites of analytes with a broad polarity range are to be extracted simultaneously from a single water sample, such as organochlorine, triazine and organophosphate pesticides, or endocrine disrupters.
