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 presents a simple method for the extraction and subsequent detection of both the traditional hydroxy metabolites and the biologically active dihydroxy metabolites in serum. High analyte recoveries and low ion suppression were demonstrated, allowing limits of quantitation at low pg/mL levels for the di-OH metabolites and < 1 ng/mL levels for the OH metabolites.

Most drugs are excreted in urine as glucuronide conjugates. Hydrolysis using a beta-glucuronidase enzyme to convert the metabolites to their “free” form for analysis increases sensitivity. Red abalone (Kura Biotech), abalone (Campbell Scientific), and recombinant (IMCSzyme) beta-glucuronidase enzymes were evaluated to determine which provided the most complete hydrolysis of glucuronide metabolites without effecting the overall recovery of non-conjugated compounds.
EVOLUTE EXPRESS CX 96-well plates were used to extract hydrolysed urine samples, and the impact of th enzymes was compared.

EXPRESS represents a leap forward in high
throughput solid phase extraction. The EVOLUTE
EXPRESS range of 96-well SPE plates combines
powerful EVOLUTE sorbent chemistry with innovative
features that enhance productivity by optimizing
or even eliminating the need for some traditional
steps in the SPE procedure. By truly eliminating the
need for conditioning and equilibration, samples
can be prepared by loading the plate, washing away
interferences and eluting with compatible solvents

Pharmaceutical companies and those who supply them with intermediates, constantly strive to produce API’s and
intermediates of the highest purity. At the same time, many established production facilities face strong competitive
pressures to produce high quality product at lower costs. Drug substance impurities are wide-ranging as described in the
International Conference on Harmonization (ICH) “Impurities in new Drug Substances”1. Of particular concern in recent
years are the ‘genotoxic compounds.
