UN9211/9212/9213/9214/9215/9216/9217/9218/9219/9210/921D/921E/921F/921K/921L/UNR921M/921N/921AJ/921BJ/921CJ Silicon NPN epitaxial planer transistor For digital circuits. Costs can be reduced through downsizing of the equipment and reduction of the number of parts. SS-Mini type package, allowing automatic insertion through tape packing and magazine packing.
本文介绍了一种使用0.18 mm id高效GC列(20 m×0.18 mm id×0.18µm膜厚)和氦载气进行合同实验室程序(CLP)农药分析的方法。DB-17ms固定相用于初步分析,DB-XLB固定相用于确认。使用该方法,在11分钟内即可完成22种CLP农药的初步分析和确认,比使用0.32 mm id列减少了35%的时间。
本报告介绍了使用HP-608毛细管柱分析含氯农药和PCB的方法。氯代农药和PCB在EPA 608、8080、8081和CLP农药方法中均被检测，这些方法用于废水和固体废物的评估。在2.4 ml/min的恒定流量下，使用Agilent 5890 Series II GC+EPC对分流和进样技术进行了比较。
