氮吹儀采用惰性氣體對加熱樣液進行吹掃，使待處理樣品迅速濃縮，達到快速分離純化的效果。該方法操作簡便，尤其可以同時處理多個樣品，大大縮短了檢測時間。被廣泛應用于農(nóng)殘檢測，制藥行業(yè)和通用研究中的樣品批量處理。 Pressured gas blowing concentrators carry on inert gases blowing on the heating samples, concentrate the samples repidly, in order to achieve fast seperation efforts. Especially they can operate muti-samples simultaneously, shorten testing time. They are widely used in detect pesticide residues, pharmacy and muti-samples experiment in general areas.
