A Sensitive Method Approach for Chromatographic Analysis of Gas Streams in Separation Processes Based on Columns Packed with an Adsorbent Material
Table 2
Illustrative data results obtained for the single-point calibration procedure of the sampling gas mixtures used experimentally. Run 1 reports the single point calibration experiment, while runs 2 and 3 denote the respective tuning runs.
