One of the most common flash purification challenges is
dealing with hard-to-dissolve crude samples. Because polar
solvents cause poor chromatographic results when used as
injection solvents in normal-phase flash chromatography, other
sample load options are needed.

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.

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.
