US Classification:
436128, 436 56, 436111, 436173, 436175
Abstract:
A method of identification and quantitative analysis of aldehydes and/or ketones in a sample by mass spectrometry using stable isotope labeled oxime internal standards or stable isotope labeled hydrazone internal standards is provided. Stable isotope labeled oxime internal standards are synthesized by reaction of an authentic sample of aldehydes and/or ketones with a stable isotope labeled alkoxylamine reagent while stable isotope labeled hydrazone internal standards are synthesized by reaction of an authentic sample of aldehydes and/or ketones with a stable isotope labeled alkylhydrazine reagent. A non labeled version of the stable isotope labeled reagent is used to convert aldehydes and/or ketones in the sample to the non labeled version of the stable isotope labeled oxime or hydrazone internal standards.
Method Of Analysis Of Alcohol By Mass Spectrometry
Hoa Duc Nguyen - Orange CA, US Trinh Duc Nguyen - Anaheim CA, US Duc Tien Nguyen - Westminster CA, US
International Classification:
G01N 24/00 G01N 33/14
US Classification:
436173, 436 24
Abstract:
Method of identification and quantitative analysis of alcohol(s) in a sample by mass spectrometry using stable isotope labeled internal standard is provided. Said internal standard is prepared by reaction of an authentic sample of said alcohol with a stable isotope labeled reagent, and is added to a sample containing said alcohol. Said alcohol in said sample is then quantitatively converted to a chemical compound of identical structure, except the stable isotope atoms, as that of said internal standard using a non-labeled reagent. Said sample is then extracted and the extract is analyzed by mass spectrometry. Identification and quantification of said alcohol are made from a plot of ion ratio of said converted alcohol to said internal standard versus alcohol concentration.

Abstract:
Method of identification and quantitative analysis of carboxylic acid(s) in a sample by mass spectrometry using stable isotope labeled internal standard is provided. Said internal standard is prepared by reaction of an authentic sample of said carboxylic acid with a stable isotope labeled reagent, and is added to a sample containing said carboxylic acid. Said carboxylic acid in said sample is then quantitatively converted to a chemical compound of identical structure, except the stable isotope atoms, as that of said internal standard using a non-labeled reagent. Said sample is then extracted and the extract is analyzed by mass spectrometry. Identification and quantification of said carboxylic acid are made from a plot of ion ratio of said converted carboxylic acid to said internal standard versus carboxylic acid concentration.

International Classification:
G06F 11/00
US Classification:
714 631, 714 3814
Abstract:
According to one embodiment, a debugging tool includes a processor and logic, that when executed by the processor, causes the processor to: receive a Volume Table of Contents (VTOC)/INDEX data set for a first VTOC/INDEX data of a remote system, create second VTOC/INDEX data (which is a replicated version of the first VTOC/INDEX data of the remote system) from the VTOC/INDEX data set, execute a second scenario (which is a replicated version of a first scenario that was executed on the remote system using the first VTOC/INDEX data that caused the error) using the second VTOC/INDEX data to reproduce an error, and set up trace points in the second VTOC/INDEX data to start a debugging session while executing the second scenario using the second VTOC/INDEX data. Other systems, methods, and computer program products are also described according to various other embodiments.

US Classification:
436106000
Abstract:
Method of identification and quantitative analysis of primary and/or secondary amine(s) in a sample by mass spectrometry using stable isotope labeled internal standard is provided. Said internal standard is prepared by reaction of an authentic sample of said amine with a stable isotope labeled reagent, and is added to a sample containing said amine. Said amine in said sample is then quantitatively converted to a chemical compound of identical structure, except the stable isotope atoms, as that of said internal standard using a non-labeled reagent. Said sample is then extracted and the extract is analyzed by mass spectrometry. Identification and quantification of said amine are made from a plot of ion ratio of said converted amine to said internal standard versus amine concentration.

International Classification:
G01N033/53 G01N033/543
US Classification:
435007100, 436518000
Abstract:
Method of automated metabolic stability analysis of library of compounds by mass spectrometry using stable isotope labeled internal standards is provided. Said internal standards are prepared in situ by reaction of an authentic sample of said library compounds with a stable isotope labeled reagent. In an automated fashion, cytochrome P450 enzyme systems are added to said library compounds; said reactions are terminated after certain periods of time by addition of an organic solvent containing equal amounts of said labeled internal standards; said terminated enzyme reactions are treated with a non-labeled version of said stable isotope labeled reagent to convert remaining library compounds to compounds of identical structures, except the labeled atoms, as those of said labeled internal standards; said conversion reactions are extracted and the extracts are analyzed by isotope dilution mass spectrometry to determine the percentage of library compounds remaining after enzyme reactions.
