Volatile carboxylic acid profiling in physiological fluids: direct injection into a gas chromatograph/mass spectrometer.
نویسندگان
چکیده
We present a procedure for the profiling of the volatile carboxylic acids and neutral compounds in blood or urine using the direct injection of the acidified sample into a gas chromatograph interfaced with a mass spectrometer by a jet separator. The non-volatile components remain at the head of the SP-1000 column while the volatile components move through the column. Up to sixty physiological samples can be analyzed before any degradation in mass spectrometer operating parameters is observed.

Volatile carboxylic acid profiling in physiological fluids.
Many inborn errors of metabolism are characterized by an increase in the concentrations of various carboxylic acids in blood and urine. For example, the metabolic disorders propionic acidemia [ 11, methylmalonic aciduria [ 2,3], maple syrup urine disease [4], isovaleric acidemia [ 41 and glutaric aciduria type II [ 5,6] show increased amounts of volatile carboxylic acids in blood or urine. Proc...
متن کاملApplication of NeedlEx® to the Analysis of N-methyl O-aryl Carbamates in Urine and Serum Samples
The use of carbamates has been implicated in several suicides and in accidental poisoning. Rapid identification of these carbamates in clinical samples can direct the course of medical intervation and help save lives. In this study, we describe a new, operationally simple, and rapid method that employs a gas chromatograph (GC) or gas chromatograph-mass spectrometer (GC-MS) coupled to a NeedlEx®...
متن کاملVolatile aroma compounds in various brewed green teas.
This study identifies and semi-quantifies aroma volatiles in brewed green tea samples. The objectives of this study were to identify using a gas chromatograph-mass spectrometer (GC-MS) paired with a headspace solid-phase micro-extraction (HS-SPME) the common volatile compounds that may be responsible for aroma/flavor of the brewed liquor of a range of green tea samples from various countries as...
متن کاملEvaluation of a benchtop capillary gas chromatograph-mass spectrometer for clinical toxicology.
We evaluated the Hewlett-Packard 5995B benchtop capillary gas chromatograph-mass spectrometer (GC-MS) for its ability to identify drugs commonly detected and (or) measured in the clinical toxicology laboratory. Initial experiments indicated that the instrument as originally configured, with an isolation valve between the gas chromatograph and mass spectrometer, was unsatisfactory for the identi...
متن کاملDerivatization in mass spectrometry --7. On-line derivatisation/degradation.
The review describes on-line derivatization/degradation methods employed in mass spectrometry to solve some structural and analytical problems. Advantages and applications of various positions of reaction systems connected mainly to a mass spectrometer or a gas chromatograph/mass spectrometer are considered. Among these are reaction systems connected directly to the mass spectrometer (reaction ...
