(St. Louis, MO, June 2015): At the recently-completed, ASMS 2015, Sylvain Letarte, PhD, ing, Phytronix Technologies, presented Ultra-Fast Separation and Quantification of Isobaric Barbiturates in Serum using LDTD-MS/MS combined with differential mobility spectrometry. In this ground-breaking oral presentation conducted at the show, Phytronix described the instrumentation, extraction procedure, serum sample analysis and conclusions reached in quantification of isobaric barbiturates in serum in 9 seconds using LDTD-DMS-MS/MS. SelexION technology allows separation of two isobaric molecules with similar structure by varying the COV parameters. Intra-run precision and accuracy comparable to LC-MS and GC-MS methods was achieved.
