ISOLUTE EPH SPE columns and associated methodologies have been optimised to efficiently fractionate EPHs into aliphatic and polycyclic aromatic (PAH) fractions. The principle is similar to the approach taken by the Massachusetts Department of Environmental Protection (MADEP) and TPH criteria working group (TPHCWG) methods. However, compared to these methods, the ISOLUTE EPH fractionation column has been significantly reduced in size and the sorbent has been optimised in order to reduce solvent volumes and provide an automation compatible fractionation column. Automation of the fractionation process has been achieved without carryover of PAHs into the aliphatic fraction. Environmental contamination, ISOLUTE, PAH, Polyaromatic hydrocarbons, soil,

Over the past decade, the need for non-invasive drug screening that that precludes sample adulteration has become attractive. As a result, detection using oral fluid devices for Drugs of Abuse (DOA) has come to the vanguard of the scientific community. The use of Supported Liquid Extraction (ISOLUTE® SLE+) prior to LC/MS or GC/MS can improve sample cleanliness without forfeiting sample detection within a diverse panel of DOAs. Here, we demonstrate the effects of altering elution solvent polarity and pH for sample pretreatment upon the simultaneous recovery of 34 compounds comprised of opioids, benzodiazepines, and stimulants to directly measure the effects of the oral fluid buffer, OraSure™, upon extraction and signal intensity at presumed LOQs.

The Atlantis pressure scale-up workstation performs and optimizes gas/liq and gas/liq/solid, heterogeneous reactions with the unique ability to monitor live gas consumption. Process Chemists can easily load experiments with push-button hardware and precisely control and monitor reactions with simple-to-use software. The Atlantis system controls reaction parameters automatically to eliminate sample degradation and in addition, provides concise reaction data reports with live molar uptake rates for better analysis.

Product Notes

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.

This application note describes the fully automated extraction of carboxy-THC from urine, following base hydrolysis prior to GC/MS analysis. The method was automated using Biotage® ExtraheraTM, configured for use with EVOLUTE EXPRESS ABN columns. The method delivers clean extracts and analyte recovery of 90% with RSD lower than 10% for carboxy-THC and its deuterated internal standard. Using the Biotage® ExtraheraTM, 24 samples were extracted in approximately 38 minutes. The limit of quantitation of 2 ng/mL is below the SAMHSA/ EWDTS confirmation cut off of 15 ng/mL for workplace testing applications.
