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)
