產(chǎn)品特點(diǎn):

保護(hù)柱的作用：•減少了污濁樣品對(duì)柱子性能的影響.•減少了故障停機(jī)時(shí)間和維護(hù).

• 防止嚴(yán)酷的“蒸汽清洗”式的水注入導(dǎo)致的柱子惡化，延長(zhǎng)柱使用壽命.
• 使用溫度: 430°C.
當(dāng)吹掃捕集系統(tǒng)、大氣監(jiān)測(cè)設(shè)備或其他儀器的通道攜帶有蒸汽冷凝水時(shí)，去活的柱管會(huì)因?yàn)楫a(chǎn)生自由硅羥基而變得活潑。這些硅羥基吸附像乙醇和二醇這樣活潑的含氧化合物。Restek化學(xué)家已著手解決這一問(wèn)題，并找到了解決方案-- - Hydroguard ®去活處理。經(jīng)一種獨(dú)特的去活化學(xué)反應(yīng)生成了一個(gè)不易起水解作用的高致密的表面。 這種高致密的表面覆蓋了Hydroguard®去活涂層能夠有效的阻止水蒸氣滲透到熔融石英表面以下 。使用Hydroguard®柱管可連接GC主機(jī)到：
• 吹掃捕集系統(tǒng).
• 頂空分析器.
• 大氣檢測(cè)設(shè)備和預(yù)濃縮裝置.
• 其它能夠捕集/熱脫附水蒸氣的儀器.
• 任何要求樣品有惰性、疏水性的分析儀器.
