Progress in SIFT‐MS: Breath analysis and other applications

Mass Spectrometry Reviews, 2011
AbstractThe development of selected ion flow tube mass spectrometry, SIFT‐MS, is described from its inception as the modified very large SIFT instruments used to demonstrate the feasibility of SIFT‐MS as an analytical technique, towards the smaller but bulky transportable instruments and finally to the current smallest Profile 3 instruments that have ...

Ambient analysis of trace compounds in gaseous media by SIFT-MS

The Analyst, 2011
The topic of ambient gas analysis has been rapidly developed in the last few years with the evolution of the exciting new techniques such as DESI, DART and EESI. The essential feature of all is that analysis of trace gases can be accomplished either in the gas phase or those released from surfaces, crucially avoiding sample collection or modification ...

SIFT-MS analysis of Iberian hams from pigs reared under different conditions

Meat Science, 2015
The aim of this study was to investigate the usefulness of a Selected Ion Flow Tube-Mass Spectrometry (SIFT-MS) equipment to tentatively quantify relevant volatile compounds of dry-cured Iberian ham, and to differentiate Iberian hams from pigs reared at four different conditions yielding different commercial grades.

Time-integrated thermal desorption for quantitative SIFT-MS analyses of atmospheric monoterpenes

Analytical and Bioanalytical Chemistry, 2019
A new time-integrated thermal desorption technique has been developed that can be used with selected ion flow tube mass spectrometry, TI-TD/SIFT-MS, for off-line quantitative analyses of VOCs accumulated onto sorbents. Using a slow desorption temperature ramp, the absolute amounts of desorbed compounds can be quantified in real time by SIFT-MS and ...

SIFT-MS: development of instrumentation and applications.

2007
Data is presented for a range of experiments that have been performed using a selected ion flow tube (SIFT) instrument operated at room temperature (~ 298K) with carrier gas pressures typically in the range of 0.3 – 0.6 Torr. The majority of the experiments discussed are performed on a Voice100 instrument that has not been described in detail ...
