VWR® PESTINORM®, Gas Chromatography (GC) Certified Reference Material

目录号: (VWRC91009.050)

供应商: VWR Chemicals

描述: Due to its excellent separation capacity and its high sensitivity gas chromatography is a widely used technique for analytical purposes. In order to get proper identification and quantification results of the analysed compounds, reference standards are needed. These PESTINORM® reference substances can be used for the characterisation of GC column properties. In addition they may also be used for the identification of unknown compounds in a gas chromatogram or as standards in quantitative GC analysis.
