Designed polymers are a class of selective resins with engineered selectivities for particular target molecules or ‘classes’ of molecules. These designed polymers are obtained by careful tuning of their surface chemistry and morphology which allows them to exhibit unique separation capabilities. The tailored and optimized selectivity of designed polymers is utilized to conduct difficult separations that are not able to be accomplished with conventional separation resins or other techniques.

The formation of diarylethers by reacting an arylhalide and phenol is usually a reaction demanding long reaction times, high temperatures and strong bases, in order to obtain acceptable yield. The substitution patent of the electrophile and the nucleophile affects the reaction times mostly. A sterically hindered electrophile and a strongly deactivated nucleophile as outlined in the (Scheme 1) below, gives a very low yield (13 %) at conventional reflux for 2 weeks.1,2 Remainder was
recovered starting material. We have previously reported the dramatically shortened reaction time to 1 hour along with improved yield running the reaction outlined in the Scheme by heating by microwaves.

Endogenous phospholipids present in biological fluids are a major problem in LCMS/ MS analysis as they are often very difficult to remove during sample preparation. When phospholipids are not removed, they retain very strongly on reversed phase analytical columns. If high organic (end of run) washes are not incorporated into the LC methods these matrix components may elute in subsequent analyses causing regions of suppression/enhancement leading to inaccurate quantitation. This poster evaluates the use of polymer-based solid phase extraction (SPE) sorbents, incorporating hydrophobic and various mixedmode retention mechanisms to address the problems associated with phospholipid removal.

Endogenous phospholipids (outline structure shown in
Figure 1.) present in biological fluids are a major problem
in LC-MS/MS analysis. Due to their strong retention
characteristics in reversed phase chromatography
phospholipids tend not to elute as discrete peaks and are
often very difficult to separate from analytes of interest.
This co-elution often leads to areas of suppression or enhancement in the chromatogram which in turn can cause
quantitation issues. Supported liquid extraction (SLE) is an
analogous technique to traditional liquidliquid
extraction. This poster compares phospholipid removal using a wide variety of solvent combinations, pH control and polar extraction solvents on supported liquid extraction plates

In all areas of analytical laboratory testing it is vital to ensure proper quality measures are in place to reduce or eliminate cross contamination between samples, which could result in false positive and/or false negative results. In many cases sample carryover in the LC/MS system is checked early on in the method development process. However, one area that can often be overlooked the sample preparation stage. This involves all aspects including pipetting, sample transfer, extraction protocol, evaporation and mixing steps. This poster examines various stages of the sample preparation process to determine the potential for cross contamination and present approaches to minimize and or eliminate the effect. This is demonstrated via a series of dye experiments combined with analyte testing using LC-MS/MS.
