• Convenient and economical leak-free guard cartridge system, extremely easy to
install.
• Versatile configuration protects against all levels of contamination.
• Integral design eliminates troublesome tubing connections.
The system’s foundation consists of the analytical column configured with our exclu
sive Trident end fitting and XF fitting. This configuration contains the standard inter
nal frit as well as a replaceable cap frit, which easily can be changed without disturbin
the packed bed. Changing the external frit can reverse the effects of accumulated parti
cles, such as high backpressure or peak distortion. To obtain this basic configuration
simply order any Restek HPLC column, and add the suffix -700 to the catalog numbe
for the column. (Nominal additional charge.)
For maximum protection against contaminants and particulate matter, the system ca
be configured with an integral guard cartridge holder (XG-XF), a guard cartridge, an
a replaceable external frit. To obtain this configuration, simply order any Restek HPL
column, add the suffix -700 to the catalog number for the column, and order th
appropriate XG-XF male fitting (cat.# 25026 or 25062) and Trident guard cartridges
