一种称为脱吸电子喷雾离子化(DESI)的方法据称可以加快进行食物样品的分析,这样可以加速食品的释放。不然化验的时间将影响食品上市的时间。该方法系用质谱方法分析细菌和其他的致病菌,通常的方法需要数小时,样品的制备和特殊处理也花费时间和财力及精力, One known method called Desorption Electron Spray Ionization (DESI) is said to speed up the analysis of food samples, which can speed up the release of foodstuffs. Otherwise, the timing of the test will affect the time to market food. The method uses mass spectrometry to analyze bacteria and other pathogenic bacteria. The usual method takes several hours. The preparation of samples and the special treatment also take time and financial resources and effort,
