Application Notes

The 17th revision of Japanese Pharmacopoeia stipulates a method using gas chromatography as a method for measuring the alcohol content in products. This time, we will report the results of pretreatment and analysis with reference to "Alcohol number measurement method" test for Pharmacopoeia.

InertCap ProGuard is a capillary column with an integrated guard column, which protects the column from impurities that may be present in the sample.? With InertCap ProGuard, the life of the capillary column can be extended, even when analyzing samples containing large quantities of contamination.

Assuming a fire site where fuels such as gasoline, kerosene, and light oil were used, we used HandyTD TD265 to perform a concentration analysis of the components that volatilize from the recovered material after combustion. In the recovered material, components derived from the fuel used for combustion were detected.

Based on this, the acceptable changeable range of conditions is widened, enabling easier requirement study.\r\nIn this report, an analysis was implemented by changing the column size within the range specified in [2.00 General theory of chromatography] for JP18 Purity Test ...
