產品特點:
分析者通常會認為很難做到將保護柱與分析柱連接時不漏氣。為此Restek提供了一種Integra-Guard™一體化保護柱。這種一體化保護柱是將保護柱和分析柱合并成連續(xù)長度的柱管，消除了連接以及與連接相關的問題！這種一體化的保護柱結構保證了完全沒有漏泄。這種一體化的保護柱按尺寸系列供應，保證沒有漏泄。通過熱縮連接方式，保護柱和分析柱是被標記分離的。一體柱裝在不會被擠壓的柱籠架中免遭破損壞。
Restek提供多種一體化毛細保護柱，種類如下表所示。與其他的連接式保護柱（甚至包括自己組裝的）相比，這種保護柱方式價格均比較便宜。如果您正在使用或者考慮使用保護柱，請及時與我們聯(lián)系并咨詢Integra-Guard™柱的相關問題！
無需連接得到保護!

－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
The capillary column you have received has a “built-in” guard column. The built-in guard column is a 5- to 10-meter section of the capillary column that has been deactivated, but not coated with stationary phase. Because it is an integral part of the capillary column it has been tested for bleed and inertness along with the coated section of the column.
The guard column should be installed into the inlet side of your GC system. When first received, you can easily identify the guard column end of the capillary column by the tag labeled “Guard column end”. Once this tag has been removed, you can still identify the guard column end because it is tied separately from the coated portion of the column on the side of the cage that the metal tag has been attached.
Both the guard column and coated column sections are tied into approximately 5-meter bundles. You can determine the exact length of the guard column by counting the number of column loops and multiplying by 0.56 meters.
As sections of the guard column become contaminated, they can be removed. Typically 1 or 2 loops from the inlet side will need to be removed to bring the column back to acceptable performance. Eventually, all of the guard column may be removed. Once this occurs, a new guard column can be installed using a Press-
Tight® connector (cat.# 20400) or a Vu-Union® connector (cat.# 20418). For more information on guard columns and Press-Tight® or Vu-Union® connectors, please refer to Restek’s Chromatography Products Catalog, or call Technical Service.
