Effect of flow rates and sample volume on Stop and Flow measurements. The ethylene concentration curves were obtained from using the Stop and Flow method at different flow rates to measure the same concentration of ethylene gas in a large volume (196 nL L−1 in 520 mL; a) or a small (92.31 nL L−1 in 10 mL; b). The coloured diamond are the measured concentrations using the respective flow rates, while the black diamond is the actual concentration
