*沃特世VanGuard保護(hù)柱 特點：
延長分析柱壽命
VanGuard預(yù)柱和保護(hù)柱經(jīng)過優(yōu)化設(shè)計，能夠在保護(hù)和延長分析柱使用壽命的同時，不犧牲色譜性能。VanGuard保護(hù)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(hù)的理想之選。
*沃特世VanGuard保護(hù)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(hù)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(hù)柱優(yōu)勢
zoom | VanGuard預(yù)柱能維持UPLC色譜柱的柱效
VanGuard預(yù)柱具有一體式設(shè)計，不會對ACQUITY UPLC分離的整體分析方法造成任何影響，您仍可實現(xiàn)更高的分析效率、分離度及更大的分析通量。低擴(kuò)散的2.1 x 5 mm Vanguard預(yù)柱可直接連接至ACQUITY UPLC色譜柱進(jìn)樣口，并且提供各種ACQUITY UPLC色譜柱固定相的規(guī)格。

經(jīng)濟(jì)高效的HPLC和UHPLC色譜柱保護(hù)產(chǎn)品
VanGuard保護(hù)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(hù)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。

VanGuard保護(hù)柱*配置
保持HPLC/UHPLC分離效率
VanGuard保護(hù)柱經(jīng)設(shè)計優(yōu)化，在各種分離條件下對色譜的影響都極低。其低死體積設(shè)計可zui大程度降低峰擴(kuò)散和峰拖尾，從而保持分離度和分析效率。
