大連依利特高效液相色譜柱 保護柱
隨著色譜柱使用時間的增加，色譜柱分離效能下降、柱壓增高，原因主要是由色譜柱柱頭被污染引起的，而色譜柱整個柱床并未被嚴重破壞。如果能在色譜柱的前端加一短柱，讓所有的污染或破壞均在此發(fā)生，就可以達到保護相對較昂貴的色譜柱作用，這就是保護柱的設計初衷，也是保護柱的作用所在。通常情況下，保護柱所裝的填料與色譜柱的填料相同或相似，考慮到價格和使用過程中的其它因素，填料的粒度可以稍大；大連依利特設計生產(chǎn)的“jia杰"保護柱采用全新設計的10mm可換柱芯式結構，經(jīng)大量實驗證明，既能夠保證較強的保護作用，具有較高的使用壽命，又降低了對色譜柱的影響。為了保證保護柱的質量，每個柱芯在出廠前均進行嚴格質量評價。
