The back stress with the system gets minimized with a rise in column temperature. This happens since the viscosity of the cellular period decreases, causing a minimize in flow resistance in the column.Using a column heater or Column chamber using a thermostat aids enhance performance and lessen the analysis time. The elevated temperature on the HPL
