Effect of temperature on the B/F ratio using 4.5 kV separation voltage.

	Temperature (°C)*	B/F	RSD (%)**
No Cooling	28	1.43	3.50
Air Cooling	26	3.53	1.13
Active Cooling	25.0	4.49	1.33
	23.0	5.31	1.50
	21.0	5.76	1.38
	19.0	4.80	0.62
	17.0	2.39	1.25

^*The precision of the temperature at 28 °C was ± 1 °C, at 26 °C was ± 0.4 °C, and for others were ± 0.1°C

^**The standard deviations reported were determined from 5 consecutive separations
