YMC offers an optimum connector to avoid connection problems in HPLC, such as dead columns: Sure-Fit™-connectors.
To use YMC’s guard cartridges YMC provides two guard cartridge holder systems to guarantee the optimum protection for every YMC analytical column. For semi-preparative columns guard cartridge holders are also available.

While different column hardware manufacturers have introduced a variety of connecting port geometries throughout the years, the Sure-Fit™ Connector represents an ideal tool to avoid dead volumes, irrespective of the column brand, when connecting different columns to a given HPLC system.
YMC highly recommends the use of the Sure-Fit™ connector due to its internal spring tensioned mechanism that automatically self-adjusts to any port depth while maintaining constant pressure on the capillary tubing to guarantee a connection free from any dead volume. This makes column changeovers easy, especially as there are no tools required. Sure-Fit™ connectors are fingertight to 6,000 psi (420 bar) and are available in a range of capillary tubing i.d.’s and lengths.
YMC offers two different analytical guard cartridge holder concepts. The universal finger tight system is for all column internal diameters from 1.0 to 4.6 mm id (XPGCH-Q1 for 10 mm cartridges and XPGCH-Q2 for 20 mm cartridges).
This system guarantees a low dead volume connection between the guard cartridge and the main column irrespective of the type of column fitting used. The guard cartridge holder gives leak-proof connection to the analytical column up to 6,000 psi (420 bar).
In addition YMC offers a specific integral guard cartridge holder (XPGCS-Q1 for 10 mm and XPGCS-Q2 for 20 mm length cartridges with 1.0; 2.1; 3.0 or 4.0 mm inner diameters).
This holder is screwed directly on the YMC cartridge column system in place of the removable end fitting (part numbers ending in QT). The guard cartridges are inserted in the holder cavity without the need to use any tools. These integral guard cartridge holders will not attach to columns with part numbers ending in WT or PT.
For semi-prep columns cartridges and holders of 20 mm length and 30 mm inner diameter are available (more dimensions on request).
For semi-prep columns cartridges and holders of 10 mm length by 20 mm inner diameter and 30 mm inner diameter are available.
As the holder for these cartridges feature Parker-compatible fittings (port depth 0.09 inch). It is essential that slip-free fittings (such as Sure-Fit™ connectors) are used or specially made stainless steel fittings with stainless steel capillaries are made up so that differences between Valco-compatible (port depth 0.08 inch), Parker-compatible (port depth 0.09 inch) and/or Waters-compatible (port depth 0.13 inch) column endfittings can be accommodated.
Due to the higher flowrates involved in semi-prep and prep chromatography the use of PEEK capillaries should be avoided if possible.
The part number of semiprep guard cartridges ends -CC (e.g. AA12S05-0120CC for 20 mm i.d. and AA12S05-0130CC for 30 mm i.d.). The part numbers for the guard cartridge holders are XPCHSPW2 (20 mm i.d.) or XPCHSPW3 (30 mm i.d.).
