Ethyl glucuronide (EtG) and ethyl sulphate (EtS) are specific metabolites formed within the body after the ingestion of alcohol. In forensic toxicology, when tested together they provide more specific evidence of alcohol intake. This application note demonstrates the simultaneous extraction of both EtG and EtS in the same assay and represents further optimization of AN718 which showed single EtG extraction without EtS. Recoveries for EtG range from 90-105% and 80-103% for EtS across two formats of EVOLUTE AX columns with RSDs <10%. The LOQ is 10 ng/mL for EtG and 2 ng/mL for EtS across both EVOLUTE AX formats.

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%.

This poster summarizes various sample preparation strategies for the
extraction of MMA from serum without the necessity for derivatization, prior to LC-MS/MS analysis. A range of sample preparation techniques of varying complexity were evaluated: protein precipitation, phospholipid depletion, supported liquid extraction and solid phase extraction using both silica and polymer-based mixed-mode anion exchange chemistries.
Method performance was evaluated for evaporative effects, assay recovery, ion suppression and phospholipid removal.

This poster examines various factors in the development and optimisation of a SPE-LC-MS/MS method for extraction of catecholamines from plasma.
The final method utilizes EVOLUTE EXPRESS WCX plates in either standard SPE or fast Load-wash-elute modes, and incorporates a series of wash steps to optimise analytical sensitivity. Low elution volumes mean no evaporation step is required, and LLOQ is 20mg/mL or lower for each of the analytes.

EVOLUTE® EXPRESS SPE columns and plates combine sorbent wettability with optimized SPE components, allowing better flow consistency and in many cases eliminating the need for SPE column conditioning; thus simplifying and reducing extraction processing. This poster compares the performance of various EVOLUTE EXPRESS column chemistries using 10-500 mg bed weights, in order to investigate whether sorbent conditioning and equilibration steps are truly required.

This poster describes a reduced workflow solid phase extraction method for extraction of vitamin B7 (biotin) from human serum. Using EVOLUTE EXPRESS AX 96-well plates, the traditional sorbent conditioning and equilibration steps are not required, meaning the sample can be applied directly to the dry plate. Post extraction evaporation is also eliminated.

Is there an expiry (‘best before’) date for ISOLUTE and EVOLUTE sample preparation products?
There is no fixed expiry date for these products.
All ISOLUTE and EVOLUTE products are packaged in inner metal laminate barrier bags, which provide an effective barrier to oxygen and moisture penetration. Recommended storage conditions are standard (see below).
We have no indications that the performance of non-bonded phase SPE sorbents is affected by long term storage, under recommended conditions.
