The TurboVap II evaporation system concentrates organic solvent extracts using steam and nitrogen. An optical sensor allows for unattended operation, by stopping the concentration at the 1 mL endpoint. This set-up is ideal for environmental analysis. The patented vortex shearing action provides rinsing as the sample concentrates to maximize recoveries. The six position standard internal rack in the TurboVap II can be replaced with a six position rack to accommodate the new 40 mL stemmed and graduated Dionex ASE vials.

The TurboVap LV Evaporation System concentrates organic solvent extracts using steam and nitrogen. A timer allows for unattended operation. This set-up is ideal for residue analysis (“going to dryness”) or analyses that can be taken to a low volume. The patented vortex shearing action provides rinsing as the sample concentrates to maximize recoveries. The internal rack in the TurboVap LV is 24 positions and can be removed to use on a benchtop. A removable “plate” allows the user to convert the rack from 40 mL to 60 mL vials and vice versa. This rack can also be used for the new graduated, stemmed 40 mL Dionex vials.

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.

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.

Cyclosporine is an immunosuppressant used in organ transplants to overcome rejection. Following the transplant of a heart, liver, kidney or lung, a patient must be regularly tested for the rest of their lives. Blood testing intervals vary from 1 month to 6 months and this rapid reference method is ideal for batch tests with the advantage of no metabolite interfer-ence which is always found in immunological methods.

The removal of interferences and sample concentration are essential steps in trace level detection of pesticides, sheep dips, herbicides and PCBs in river water, wastewaters and trade effluents. The following methods were developed by the Environment Agency National Laboratory Service facility at Nottingham using the Biotage RapidTrace for automated solid phase extraction and the TurboVap II for evaporation. The procedures are UKAS accredited and can reach detection limits of 0.001 ug/Litre for some compounds.
