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.

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.

This poster shows an extraction protocol for 12 common drugs of abuse (DOA) to be detected in breast milk using mixed-mode polymeric cation exchange solid phase extraction (SPE). Using the combination of reliable automation (on Biotage Extrahera) and SPE sample preparation techniques, a method was developed demonstrating the precision, accuracy, linearity, and sensitivity necessary for a robust quantitative workflow.

When a sample preparation technique calls for removal of compounds using SPE, it is standard practice to determine what concentrations will produce an acceptable linear range for the assay. Traditional linear regression is often performed manually using pipettes to generate an external standard curve that unknown samples are measured against.

Introduction • Solid-phase peptide synthesis (SPPS) is still often faced with challenges in the assembly of long and ‘difficult’ sequences, e.g. due to aggregation and steric hindrance giving rise to incomplete reactions. These problems have only partly been solved by new coupling reagents and solid supports. • Precise microwave heating has emerged as one new parameter for SPPS, in addition to coupling reagents, resins, solvents etc.
