Rate dependence of statistical moments of chromatographic profile on solute-solvent interactions

Abstract

adsorber is being heated, GC No. 1 door is open and the chromatograph at 25 °C for the next run, V2 is in mode 1 (closed), GC No. 2 is cooling to 25 °C. It is apparent that samples are being simultaneously collected and analyzed in a consecutive repetitive automatic pattern. It is important to note that the adsorber is purged with helium for 3 min prior to being thermally eluted to drive off any oxygen before heat is applied.Performance Experience. The monitor has been in continuous operation since July 1972. Between installation and the end of 1974, 35 000 data points have been generated. This monitor has played a major role in ensuring safe operating conditions in our plant.The automatic monitor described in this report could be readily adapted to selectively monitor almost any gaseous pollutant at the ppb level.
