Grace: Guard Cartridge Systems

To support these newly acquired column ranges, Hichrom continues to recommend the use of guard cartridges for column protection and increased column lifetime. The hardware of the Alltech All-Guard Cartridge System has been improved and all guard cartridges and holders are now supplied in this new hardware, leading to more robust and higher efficiency separations. Chromatographic selectivity will be unaffected by this change.

  • Higher pressure rating
  • Low internal swept volume

Please note that the new Hichrom guard cartridges and holders are not compatible with the old design Alltech guard cartridges and holders. Guard cartridges and holders supplied in the new improved hardware are denoted by the addition of an ‘N' at the end of the old part number.
