| 品牌 | Restek | 型號 | Hydroguard Fused Silica Guard/Retention Gap |
產品特點:
保護柱的作用：•減少了污濁樣品對柱子性能的影響.•減少了故障停機時間和維護.
• 防止嚴酷的“蒸汽清洗”式的水注入導致的柱子惡化，延長柱使用壽命.
• 使用溫度: 430°C.
當吹掃捕集系統、大氣監測設備或其他儀器的通道攜帶有蒸汽冷凝水時，去活的柱管會因為產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化學家已著手解決這一問題，并找到了解決方案-- - Hydroguard ®去活處理。經一種獨特的去活化學反應生成了一個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主機到：
• 吹掃捕集系統.
• 頂空分析器.
• 大氣檢測設備和預濃縮裝置.
• 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.

*因為存在一個大的壓降，沒有用格勒布試劑進行檢測Not .
**30米和60米長度是按5米一節標記好的.
†建議：切割60m保護柱為較短的長度。使用全長的保護柱可能引起峰的變形。
