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 report details a “load, wash, elute” weak cation exchange solid phase extraction procedure amenable to both plasma and urine samples. The extracts are subsequently injected into an LC-MS/MS system. The preliminary sample preparation method was developed at the Biotage US Applications lab (Charlotte, NC).The method was then transferred to Ionics (Bolton, ON, Canada) to facilitate the nmole/L measurements of the selected biomarkers
by laminar flow tandem mass spectrometry. The SPE-LC-ESIMS/ MS method parameters were first optimized using pooled mixed gender plasma. A set of patient samples (n=32) was later supplied by the Mayo Clinic (Rochester, MN) that had previously been analyzed by a validated referee method. The population represented measured values across a range of clinical relevance.

In this poster, an IONICS 3Q 220 triple quadrupole mass spectrometer using a load, wash, elute method protocol with recently advanced solid phase extraction (SPE) sorbent technology (EVOLUTE EXPRESS WCX) was used to perform analysis of the two compounds. As a result low levels of metanephrine and normetanephrine are detectable in plasma with short sample preparation and LC run times. This LC-MS/MS method provides a fast, sensitive, accurate, and reproducible solution for the analysis of ME and NME in plasma.

We detail here the application of new column technology to purify histamine and serotonin (Table 1) in one extraction method with the elimination of the sorbent conditioning and equilibration steps familiar to traditional solid phase extraction (SPE) method protocols prior to measurements by ultra performance liquid chromatography-electrospray ionization-tandem mass spectrometry (UPLC-MS/MS). A secondary goal of combining two LC methods into one method was also achieved.

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.
