The higher the vaporization temperature, the better. B. On the condition that the most difficult-to-separate compounds can be separated effectively, a lower column temperature should be used as much as possible. C. When selecting the carrier gas flow rate in practice, it is generally set slightly below the optimal flow rate. D. The temperature of the detection chamber should be lower than the column temperature. BC
C. When actually selecting the carrier gas flow rate, it is generally slightly lower than the optimal flow rate. D. The temperature of the detection chamber should be lower than the column temperature
