background and objectives: in the production process of foods rich in carbohydrates and some other foods containing precursors of acrylamide formation, there is the possibility of acrylamide creation, which is a mutagen and carcinogen material. this study aims to introduce and optimize a new method for determining acrylamide in potato chips using xanthydrol as a derivative representative with g...

the aim of this study was to investigate the removal of toluene from air through nano-graphene modified by ionic liquid (ng-il). the batch adsorption experiments in glass bottle of gas chromatography equipped with flame ionization detector (gc-fid) were used. graphene ultrahigh-quality synthesized by substrate-free gas-phase method in a single step and graphene sheets were deposited with ionic-...

Diaminopimelic acid was found to be a component of the cell wall of the Legionnaires disease bacterium, thus providing additional evidence that the organism is a bacterium. The presence of this amino acid was determined by gas-liquid chromatography and confirmed by gas chromatography-mass spectrometry.

Blood cultures from 196 patients with suspected bacteraemia or septicaemia were analysed by automated head-space gas chromatography, using a 25 m fused silica capillary column, when turbidity indicated growth. Gas chromatography correctly identified 105 cultures as positive and 71 correctly as negative. No false-positive results were obtained. Of the 20 false-negative chromatographic results, S...

This text, one of a series of handbooks devoted to Techniques in Pure and Applied Microbiology, is an attempt to present in one volume the fundamentals, basic methodology, and specific applications of gas-liquid chromatography in microbiology and medicine. Perhaps an overly extensive introductory review of the history, theory, development, and basic applications of gas chromatography is present...

The high-throughput gas chromatography/mass spectrometry (GC/MS) technology offers a powerful means of analyzing a large number of chemical and biological samples. One of the important analyses of GC/MS data is compound identification. In this work, novel spectral similarity measures based on the discrete wavelet and Fourier transforms were proposed. The proposed methods are composite similarit...
