Matrix components, particularly salts, proteins and
phospholipids, can lead to ion suppression resulting in
inaccurate quantitation and reduced detection limits.
Resin-based mixed-mode cation exchange SPE sorbents
are widely used for the extraction of basic compounds
from biological fluids. The dual retention mechanism
allows a two stage interference wash protocol, which
results in extremely clean extracts.
This poster will investigate the performance of
EVOLUTE™ CX for the extraction of a wide range of basic
drugs from plasma, showing high analyte recovery and
advanced extract cleanliness. The analyte suite was
selected to cover a variety of basic analytes with wide
ranging polarities (LogP values). Extract cleanliness
experiments were performed showing overall ion
suppression, then individual matrix components examined
in terms of protein and phospholipid removal.

Methylisothiazolinone (MI) is used in a variety of personal care products, such as sunscreens, lotions, cosmetics. MI is a cytotoxin and as a result there is concern because of sensitization and allergic reactions as well as cell and nerve damage. A percentage of the population is at risk from contact dermatitis when exposed to this compound at sufficient concentrations. This poster describes the use of ISOLUTE SLE+ for extraction of MI from sunscreen.

For as long as column chromatography has been practiced by
organic and medicinal chemists there has been a concern that too
much methanol in the solvent system will dissolve the column’s
silica. This concern has come about because chemists often find a
solid white precipitate in collected fractions after purification. This
phenomenon is usually noticed when dichloromethane and
methanol are used as the mobile phase solvents.
In this poster we will show the results of a study that evaluated the
degree of dissolution for both granular and spherical silica in
methanol and dichloromethane.

This poster will demonstrate SPE sample preparation strategies for the simultaneous extraction of both ethyl glucuronide and ethyl sulphate from urine, allowing cleaner extraction protocols compared to traditional dilute and shoot approaches.

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.
