The interest in analytical laboratories is driven primarily by the desire to higher laboratory throughput, better utilization of high-cost equipment and to reduce the time required to get results. As one of answers to these requirements the attention was focused on faster gas chromatographic analyses. In this introductory article the influences of different type of carrier gases and their pressure regulators, parameters of chromatographic columns, temperature programs and detectors are discussed.The interest in analytical laboratories is driven primarily by the desire to higher laboratory throughput, better utilization of high-cost equipment and to...

The set of in the history grown and also later registered genotypes of malting barley was analyzed for the selected technological quality parameters. Weight of 1000 grains and protein and starch contents were evaluated in the vegetation periods in 2004 and 2005. The drier year 2004 influenced reduction in TGW in most new as well as older genotypes. Starch content in the followed set was not affected by the year or genotype. The effect of the year on protein content in the studied set was not statistically. On the contrary, some older genotypes had higher TGW in both years compared to the current varieties and the starch content analysis showed that...
