    Changes in barometric pressure introduce an additional error to the results obtained with different types of gas analyzers. These errors can be reduced or eliminated by technical steps or by the application of corrections to the results obtained. In this paper, the authors present the results of their determinations of correction coefficients for gases measured by the Poisk chromatograph in the range of barometric pressures from 80 to 120 kPa (from 600 to 900 mm Hg). The authors designed their investigations to simulate increased and reduced barometric pressures with respect to the calibration pressure simultaneously at the outlet from the chromatographic columns (carrier gas discarding tube) and in the dosed volume. A head in the dosing volume and in the carrier gas outlets from the columns, simulating an increase in atmospheric pressure, was created by using compressed gas from a cylinder and a regulating valve; dilution, corresponding to a decrease in atmospheric pressure, was created by a flow rate stimulator and a regulating valve. A storage capacity eliminated fluctuations of the reduced or excess pressure.
