METHOD AND APPARATUS FOR PERFORMING MASS SPECTROMETRY

摘要

The invention feature devices and methods for preserving and processing samples comprising a fluid having deuterated compounds. The device of the present invention comprises a housing defining a first chamber and a second chamber. The first chamber is heated to an elevated temperature and receives the sample and performs a digestion process on the sample at the elevated temperature. The second chamber is cooled to a low temperature and receives the deuterated digested sample from the first chamber and performs one or more separation steps to isolate an analyte. The device of further comprises conduit means for containing and moving the sample into the first chamber to form a digested sample. The conduit means moves the digested sample from the first chamber to the second chamber to separate the sample to form at least one analyte. The analyte is maintained at the low temperature to preserve its deuterated form.
