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.

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.

In order to keep your RapidTrace® workstation clean, in good working order and free from contamination it is of course essential to
routinely clean and purge the fluid path. Whichever matrix and reagents are running through the system, traces of these liquids will
be left after use; proteins from plasma, precipitates from buffers or even particulates from oral fluid. Over time if the following
cleaning schedule is not observed these contaminants could cause blockages leading to malfunctions and/or cross contamination.

This poster compares the use of supported liquid extraction (ISOLUTE® SLE+) and a novel protein and phospholipid depletion plate (ISOLUTE® PLD+), for the extraction of 25-hydroxy vitamin D. The manual extraction protocols were transferred to an SPE automation platform (Biotage® Extrahera)and method performance versus manual processing compared.

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.

At the Forensic Medicine Lab at Toho University, researchers use ISOLUTE® SLE+ columns from Biotage. When dealing with samples that easily form emulsions like urine or blood, it allows researchers to use the established liquid-liquid extraction technique, saving significant amount of time on analysis. We spoke with the Head of the Forensic Medicine Lab Professor Masaru Terada.
