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.

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.
