VanGuard預(yù)柱和保護柱經(jīng)過優(yōu)化設(shè)計，能夠在保護和延長分析柱使用壽命的同時，不犧牲色譜性能。VanGuard保護柱具有多種粒徑和固定相類型供您選擇，是為沃特世的各種分析柱提供物理和化學(xué)保護的理想之選。

*沃特世VanGuard保護柱 概要：

zoom	去除顆粒污染物和化學(xué)污染物 經(jīng)常分析具有復(fù)雜樣品基質(zhì)的藥物、天然產(chǎn)物、環(huán)境和工業(yè)化學(xué)品會縮短分析柱的使用壽命并降低其色譜性能。沃特世VanGuard保護柱能通過去除流動相液體中可能存在的顆粒污染物和化學(xué)污染物來提升分析柱的性能。

VanGuard保護柱優(yōu)勢

經(jīng)濟高效的HPLC和UHPLC色譜柱保護產(chǎn)品 VanGuard保護柱是延長各種HPLC和UHPLC色譜柱壽命的通用解決方案。您不再需要更換昂貴的分析柱，僅通過更換保護柱就能使色譜恢復(fù)原始分離性能。我們專為可重復(fù)使用的卡套設(shè)計了可調(diào)節(jié)的錐箍，因此小柱能連接到任何色譜柱入口。
