InnovativeIntegra-Guard®Columns

分析者通常会认为很难做到将保护柱与分析柱连接时不漏气。为此Restek提供了一种Integra-Guard™一体化保护柱。这种一体化保护柱是将保护柱和分析柱合并成连续长度的柱管，消除了连接以及与连接相关的问题！这种一体化的保护柱结构保证了完全没有漏泄。这种一体化的保护柱按尺寸系列供应，保证没有漏泄。通过热缩连接方式，保护柱和分析柱是被标记分离的。一体柱装在不会被挤压的柱笼架中免遭破损坏。

Restek提供多种一体化毛细保护柱，种类如下表所示。与其他的连接式保护柱（甚至包括自己组装的）相比，这种保护柱方式价格均比较便宜。如果您正在使用或者考虑使用保护柱，请及时与我们联系并咨询Integra-Guard™柱的相关问题！
无需连接得到保护!

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.
