The particle size helps determine the maximum pressure rating.
Under normal HPLC conditions, a stainless steel Cogent HPLC column will have the following maximum operating pressure:
- 1.8um particle size – 10,000 psi (690 bar)
- 2.2um particle size – 9,000 psi (620 bar)
- 3um particle size – 7,200 psi (500 bar)
- 4 and 5um particle size – 6,000 psi (400 bar)
- 10um particle size – 8,700 psi (600 bar)
