Update on Guard Cartridges for Trident Holders






You may have seen my last blog post about guard holders and cartridges that we have available for our various LC product lines, “Which guard cartridges and holders go with which LC analytical columns?”

Along those lines of discussion, the following note is available to also show what specific products are currently offered for this: http://www.restek.com/Technical-Resources/Technical-Library/General-Interest/general_GNAR2492B-UNV

Reflected in the above note are some changes in what we are offering for the cartridges that are used with the Trident LC Holders.  Starting January 1, 2017, we are discontinuing the 20 mm length cartridges for the Ultra, Pinnacle, Allure and Viva columns.  This is a result of declining popularity and lower demand. We will, however, continue to sell the 10 mm length guard cartridges for the Ultra, Pinnacle, Allure and Viva columns.

In conjunction with this change, corresponding Trident guard holders for the 20 mm cartridges will be discontinued as well. This includes some of our older catalog numbers, such as 25085, 25086, 25060, and 25062 (XG-XF fitting for 20 mm).





While we feel confident that, in most cases, the 10 mm cartridge length is sufficient for analytical columns, we apologize for any inconvenience this may cause.

Thank you for your continued interest in using our LC products.
