The pressure above gravity at the head of the column. Expressed in psig, bar, atm., or MPa.

  1. […] The method uses a short column packed with 2.7μm “fused-core” silica particles that are made by fusing a 0.5μm layer of porous silica onto a solid silica particle[1]. These unique particles enable very rapid chromatographic separation at a relatively low backpressure. […]

  2. […] Such a small particle size provides nano-liquid chromatography systems with higher efficiency, resolution, selectivity, and shorter analysis time; however, it does increase the backpressure. […]
