The corrected retention time of pyridine at a carrier gas speed of 60 ml / min is 14.8 s. On the same column, the distance from the moment of injection of the sample to the maximum peak of thiophene is 11 mm (the retention distance of the non-absorbable component is 2 mm) at the speed of the graph tape 1.5 cm / min The carrier gas rate was 20 ml / min. Determine which substance will be held stronger.
