Detectors are required to quantitatively detect various substances (analytes) in gas chromatography (GC). The detector signal caused by the substance to be detected after a separation column has to be timely integrated in order to draw conclusions ab

Introduction Gas chromatography (GC) is an important tool for the analysis of trace gases. In a chromatography column, the components of the sample are completely separated from a mixture of substances. Individual gas pulses occur at the retention ti

For many decades Dragerwerk AG measurement systems have been part of the most reliable measuring methods for the quantitative measurement of pollutants in air. Based on these proven technologies the gas measuring system ”CMS“was developed [1]. Th

Two distinct proton exchange reactions occur in metastable gaseous benzylbenzenium ions, generated by isobutane chemical ionization of diphenylmethane and four deuterium-labelled analogues. Whereas the proton ring-walk at the benzenium moiety is fast

Metastable (3-phenyl-2-propynyl)benzenium ions, generated by electron impact induced fragmentation from the appropriately substituted 1,4-dihydrobenzoic acid, react by loss of ·CH3 and C6H6. The study of deuterated derivatives reveals that hydrogen/

β-Arylethyl arenium ions substituted by methyl and methoxy groups, respectively, have been generated by electron impact-induced dissociation from the correspondingly substituted 1-(β-arylethyl)-1,4-dihydrobenzoic acids. The mechanism of the arene e

Gaseous (2-phenylethy1)benzenium and (3-pheny1propyl)benzenium ions 1 and 2 are generated easily by mass spec- trometric loss of CO2H from the positive molecular ions of the corresponding 1 -(a-phenylalkyl)- 1,4-dihydrobenzoic acids 4 and 5. The majo

The interannular proton exchange in (ω-phenylalkyl)-benzenium ions, 1, (2 ⩽ n ⩽ 20) is an extremely fast process. It gives rise to the statistical distribution of the eleven protons at the two rings within the microsecond time scale even if twen
