适用范围：This part of ISO 9167 specifies a rapid method for thedetermination of the total glucosinolate content ofrapeseed using X-ray fluorescence spectrometry(XRF).lt is applicable to seeds with a normal Protein contentfrom 19 % to 23 %. For seeds with a Protein contentoutside this range, account should be taken of thetotal Protein content in the calculation of the totalglucosinolate content (see reference [4]).NOTES1 ISO 9167-1 specifies a method using high-performanceliquid chromatography (HPLC) which enables the contentof different glucosinolates to be determined individually.2 When applied to immature seed or to seed that hasbeen badly stored, for example under damp and warmconditions, the results obtained by the XRF method and bythe HPLC method (ISO 9167-1) may not agree as closely aswhen applied to normal rapeseed. The HPLC method shouldbe taken as the reference method.
