A general method for the calculation of absolute trace gas concentrations in air and breath from selected ion flow tube mass spectrometry data
A complete description is presented of a numerical method that allows the calculation, in real time, of absolute concentrations of trace gases, including volatile organic compounds and water vapour, from selected ion flow tube mass spectrometry, SIFT...

Combined use of gas chromatography and selected ion flow tube mass spectrometry for absolute trace gas quantification
The value of the gas chromatography (GC) and selected ion flow tube mass spectrometry (SIFT-MS) combination for the analysis of trace gases is demonstrated by the quantification of acetone in air samples using the three precursor ions available to SI...

The Role of Secondary Electrons in Low Pressure rf Glow Discharge
We concerned on the role of secondary electrons in low pressure rf glow discharge. The Particle in Cell/Monte Carlo computer simulations (PIC/MC) was applied to simulate the discharge. The influence of secondary electron emission yield (SEY) on the p...

Selected ion flow tube mass spectrometry (sift-MS) for on-line trace gas analysis
Selected ion flow tube mass spectrometry (SIFT-MS) is a new analytical technique for the real-time quantification of several trace gases simultaneously in air and breath. It relies on chemical ionization of the trace gas molecules in air/breath sampl...

Influence of convection on the diffusive transport and sieving of water and small solutes across the peritoneal membrane
The three-pore model of peritoneal membrane physiology predicts sieving of small solutes as a result of the presence of a water-exclusive pathway. The purpose of this study was to measure the diffusive and convective components of small solute transp...
