ES Industries guard column cartridges offer excellent protection for your column. Adding a guard column to your HPLC system extends the life of your column (up to 400%). When placed between the injector and the column, the guard column traps components that would otherwise irreversibly contaminate the stationary phase of the column, buffer against the effects of aggressive mobile phases and add capacity to your system to ensure no adverse chemical influence on sensitive separations.
The guard column cartridge packing should exactly match the column, using a guard column packed with a stationary phase different from that in the column will provide selective elimination of specific compounds. ES Industries guard column cartridges are packed by a high performance slurry technique and will not reduce system performance and are easy to use and can be changed in seconds. The complete range comprises of analytical (2.0mm I.D. and 3.2mm I.D.), semi-preparative (10mm I.D.) and preparative (30mm I.D.) sizes.
2.0mm I.D. guard cartridges are used for columns with 2.1mm I.D. to 3.0mm I.D. (HPLC, SFC & Chiral)
3.2mm I.D. guard cartridges are used for columns with 3.2mm I.D. to 4.6mm I.D. (HPLC, SFC & Chiral)
10mm I.D. guard cartridges are used for columns with 7.8mm I.D. to 20mm I.D. (HPLC use ONLY)
30mm I.D. guard cartridges are used for columns with 30mm I.D. (HPLC use ONLY)
Please Note: All guard cartridges require the use of appropriate guard cartridge holder
