PAL 系统 Micro-SPE 盒

新型 PAL 系统 μSPE 墨盒

PAL µSPE 滤芯代表了一种小型化、坚固耐用的固相萃取(SPE)技术,可实现可靠的自动化,并在不影响性能的前提下减少使用的样品和溶剂。因此,µSPE 已成为自动化环保分析流程中萃取、纯化、浓缩或过滤的新标准。

新型 PAL System µSPE 滤芯由两部分组成。所使用的聚合物材料具有化学惰性,不含沥滤剂。外部部分(1)为过滤盘(3)和吸附剂材料(4)提供了更大的容量和灵活的容积。底部出口的设计可穿透预缝隔板,直接输送到 LC 注射口。内活塞(2)具有压缩吸附剂/过滤层的关键功能,以及精确的针头导向装置,可确保安全直立输送。其基本特征是能够承受高压,防止注射器针头周围泄漏,从而能够更快地装载更大体积的样品。应用范围从食品农药、水和药物分析到法医和药理学应用。
