Abstract
In a chromatographic analysis, errors in the chromatographic analysis caused by barometric pressure variations are corrected by dividing the actual measured analysis (C.sub.m) by a correction factor which is calculated based on the actual atmospheric pressure at the time the measurement is made (P.sub.a), the atmospheric pressure at which the chromatographic analyzer system was calibrated, and the slope of a plot of C.sub.m /C.sub.a as a function of P.sub.a /P.sub.c where C.sub.a is the magnitude that C.sub.m would have if errors were not introduced by changes in barometric pressure.
