This poster demonstrates a rapid and reliable sample preparation method using Supported Liquid Extraction (ISOLUTE SLE+) to extract a suite of 30 hormone analytes from a hydrolyzed urine matrix. Single injection analysis by LC-MS/MS shows that matrix effects are eliminated by the ISOLUTE SLE+ protocol and that analyte recovery and sensitivity have excellent clinical utility.

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.

Easy to incorporate into any 96-well based assay, this essential evaporation accessory can save the cost and time of sample re-runs.
The simple but effective design prevents cross talk on evaporation, decreasing the risks of falsely elevated results. Its high specification anodized aluminum construction allows it to be reused, and it is easily cleaned between runs to prevent any potential carry over.
Biotage ACT Plate Adapter is designed for use with square well colection plates, and is compatible with 'straight needle' 96-well plate evaporators such as the Biotage SPE Dry 96 and SPE Dry 96 Dual Sample Concentrator Systems.

There are many potential causes of sample cross contamination in any clinical or forensic toxicology assay, particularly with the increasing use of the high throughput, low volume 96-well pate format for sample preparation. One recently identified area of concern is during evaporation.
During the evaporation stage, a proportional amount of analytes present in an extracted sample can contaminate surrounding wells by being carried with the volatilized solvent. When analyte concentration in the “hotspot” well is considerably higher than the analyte concentration in the surrounding wells the potential exists for extraneous analyte signal in adjacent and/or surrounding wells, thus leading to false positives which could pose severe consequences in any assay.
Mechanism for ‘hot spot’ cross talk during evaporation, resulting in carry-over from high-concentration sample wells to low-concentration wells, which show up as false positives.
Biotage® ACT Plate Adapter fits on top of the 96-well collection plate during evaporation. Evaporation gas and solvent vapours are directed away from sample tubes, eddies are reduced, and the adapter reduces the open surface area of the top of the wells, lessening the likelihood that material can re-enter and contaminate adjacent wells.
