Metabolomic Analysis of Human Urine through GC-TOFMS A workflow for metabolomic analysis of human urine samples is explored.
Urine SRMs GCxGC-HRT-TOFMS
Determining High-Concentration Aromatic Compounds in Gasolines (ASTM D5769) Using CG-TOFMS ASTM D5769 is a widely accepted standard method used in the petroleum industry for determination of benzene, toluene, and total aromatics in finished gasolines by GC-MS. A common difficulty encountered with this method is the concern with saturation of the ion source, which leads to nonlinearity in calibration curves, especially for the quantification of the high-concentration aromatics, such as toluene.
Fuel Washing BT-GC-TOFMS
Increasing Resolution in Multi-Reflecting TOFMS with Folded Flight Path Recent advancements in High Resolution Time-of-Flight Mass Spectrometry based on the Multi-Reflecting design of LECO's Folded Flight Path mass analyzers are presented.
Sub-Picogram Detection and Identification of Analytes using GC-TOFMS Yeast is difficult to study due to chemical and physical complexities of metabolites and wide concentration ranges. High-Resolution GC and GCxGC can provide efficient analysis of these complex samples.
