Method translators are extremely helpful tools when modifying/developing a gas chromatographic (GC) method. Changes to GC method parameters such as inlet/outlet pressure; flow/carrier gas type; or even capillary column dimensions will result in different retention times for our analytes and will affect resolution. Method translators calculate new analysis conditions by keeping the analytes elution temperatures the same, thus preserving elution order. Using this tool, the analysis method can be translated to a different column dimension, carrier gas type, and linear velocity, for example, with very little time spent on the method development. Method translation works well for the columns with liquid stationary phases. The purpose of this work is to present the feasibility and accuracy of method translators for the porous layer open tubular (PLOT) columns.
