Analysis of Smoker’s and Non-Smoker’s Urine Using GCxGC-TOFMS

Urine is a favored biofluid for medical testing because it is easily obtained in large volumes using non-invasive techniques. Urine can provide a window into an individual’s exposure, diet, and general health. In this investigation, a novel analytical approach was utilized for the effective characterization of compounds in two standard reference materials (NIST smoker’s and non-smoker’s urine).
