This poster investigates various parts of the SPE method development process to develop a highly sensitive LC-MS/MS method for analysis of catecholamines (epinephrine, norepinephrine, dopamine).
A number of steps are optimized to improve sensitivity of the
analytes. This includes reducing the buffer strength in the mobile
phase, reducing the buffer strength of washes, careful pH control
throughout the extraction, avoiding an evaporation step and
incorporating IPA in the reconstitution solvent.

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 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.
