At the CPSA exhibit Wednesday evening we will be showing the new DART-ET source so come by to check it out.
We also are presenting a poster titled, "Sampling from Surfaces with High Throughput DART Analysis as an alternative to traditional LC/MS/MS for Bioanalytical Assays." Here we show how rapid, simple quantitative analysis of compounds in plasma can be achieved with CV's of less than 15%. These results compare favorably with the standard approach of LC/MS/MS. If you would like more information on this, please let us know.

Rapid Screening for Food Contaminants
We would like to share some of our preliminary results with you on the rapid screening of dairy products for melamine contamination. We want to first assure you that these are all spiked samples and your Yoohoo is probably just fine. Detection of contaminants with no sample prep, no derivatization, no
extraction, no kidding!
Using 2 MRM transitions for melamine (127>85, 68), we are able to get reasonable quantitation down to 1 PPM. Using automated sampling the measurements can be accomplished in a matter of minutes. We will be doing more work to refine the method, so if you want to know more, send me a note.
