The 8860 color touchscreen provides: • Access to setpoint and status information with the ability to turn setpoints on/of Early practice of gas chromatography was done with packed columns. Such columns are still used for preparative chromatography as they can handle larger amounts of materials. Chromatography (analytical) is practiced with capillary columns, which are open tubular columns. Example Stationary Phase: Bonded; poly(50% n-octyl/50% methyl siloxane) Temp injector from the pressurized carrier gas tank (He is most common; N2 is cheapest but chromatographically less forgiving). Note that the total gas flow flows 1) through the column (green thing at bottom), 2) out the septum purge, and 3) out the split vent and always add up to the incoming flow (49 mL/min in this example).
