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.

EPA methods 8260 & 8270 cover the analysis of polychlorinated
dibenzo-p-dioxins and polychlorinated dibenzofurans
in ground & surface waters. This also now includes
1,4-dioxane and PCBs. This application note will focus on
the automated SPE of the sample rather than the detection
which usually involves GCMS or LCMS. NB The columns
and reagents used for soils and sediment analysis differ to
ground water extraction.

Endogenous phospholipids present in biological fluids are a major problem in LCMS/ MS analysis as they are often very difficult to remove during sample preparation. When phospholipids are not removed, they retain very strongly on reversed phase analytical columns. If high organic (end of run) washes are not incorporated into the LC methods these matrix components may elute in subsequent analyses causing regions of suppression/enhancement leading to inaccurate quantitation. This poster evaluates the use of polymer-based solid phase extraction (SPE) sorbents, incorporating hydrophobic and various mixedmode retention mechanisms to address the problems associated with phospholipid removal.

Ethyl glucuronide (EtG, Figure 1.) is an ethanol metabolite formed by the glucuronidation of the parent molecule. The presence of EtG in urine and plasma is a useful and sensitive biomarker of alcohol intake in forensic toxicology. EtG can be detected at very low levels and is useful in distinguishing between ingested ethanol and that which is adsorbed through the skin from ethanol. This application note has been optimized on the RapidTrace+; an updated version of the current RapidTrace software which allows the system to process smaller bed heights than were previously possible. The application note shows analyte recoveries all above 97% with RSDs >10%.

Melamine is traditionally used in making plastics, however, it’s low cost and high nitrogen content has led to exploitation in various sections of the food industry, most notably involving dairy products. Sustained melamine exposure can result in kidney stones and renal failure, with the young being most susceptible. This application note has been optimized on the RapidTrace+; an updated version of the current RapidTrace software which allows the system to process smaller bed heights than were previously possible. The application note shows recoveries of 88-90% with RSDs <10%.

The use of schedule I drugs for patient pain management therapy warrants constant monitoring of therapeutic levels in the patient. Screening patient urine samples for the free drugs is complicated by the metabolism process which converts the free drug to the -glucuronide form. Patient urine samples can be enzymatically hydrolyzed to cleave glucuronide moiety and produce the free form of drug. The target analytes can them be extracted from the urine matrix using EVOLUTE CX solid phase extraction cartridges. LOQs range from 5 ng/mL to 0.5 ng/mL with recoveries above 80% and RSD <10%

Cyclosporine (Figure 1) is an immunosuppressant drug most significantly used in post-operative organ transplants to reduce the chance of rejection of donor organs by decreasing the activity of the patient’s immune system. Subsequent to an organ transplant, patients are tested at regular intervals for the presence of very low levels of the compound. Cyclosporine is a cyclic non-ribosomal peptide of 11 amino acids and contains a single D-amino acid.

The following method addresses the extraction of 6-monoacetyl morphine from urine using
non-polar and strong cation exchange retention mechanisms. This compound can confirm
heroine use since it is a heroine metabolite, but not a metabolite of codeine or morphine
