那些HPLC常用的术语词典（英文版)

Bandwidth (tw): The width of the chromatographic
band during elution from the column. It is usually
measured at the baseline by drawing tangents to
the inflection points on the sides of the Gaussian
curve that represents the peak. Small bandwidths
usually represent efficient separations; also called
peak width (wb). See Figure 2.
Bar: A unit of pressure measurement in HPLC equal to
1 atm, 15 lb/in.2 or 0.1 MPa.
BET method: Developed by Bruner, Emmett and Teller
(BET), a method for measuring surface area that
uses nitrogen adsorption– condensation in pores at
liquid nitrogen temperature. Pore volume and pore
size distribution can also be obtained from BET
method calculations.
