the column. During injection and analysis, the valve unit directs the flow
through the autosamplers which ensures that the sample is injected
completely into the column, and that any sample residue is removed from the
metering unit and needle from before the next sampling sequence begins.
Different valves are available for the standard and preparative autosamplers.
Control of the vial temperature in the thermostatted autosampler is achieved
using an additional Agilent 1200 Infinity module; the ALS thermostat. Details
of this module are given in the Agilent 1200 Infinity thermostatted
autosampler Supplemental Manual.
