Hydrogen cyanide is readily detected in the headspace above Pseudomonas aeruginosa cultures and in the breath of cystic fibrosis (CF) patients with chronic (P. aeruginosa) infection. We investigated if exhaled breath HCN is an early marker of P. aeru

Hydride atomization and the fate of free analyte atoms in an externally heated quartz tube atomizer (QTA) were investigated employing selected ion flow tube mass spectrometry (SIFT-MS). SIFT-MS proved to be ideally suited to study water concentration

A study was performed of the reactions of protonated acetic acid hydrates, CH3COOHH+(H2O)n, with acetone molecules, CH3COCH3, using a selected ion flow-drift tube (SIFDT). The rationale for this study is that hydrated protonated organic molecules are

An 14N nuclear quadrupole resonance (NQR) spectroscopy method has been developed using the singular spectrum analysis (SSA) based on the principal components concept. For the first time, it was demonstrated that this method can be used as a low cost
