This Application Note describes the use of the Agilent 1290 Infinity II LC for the automated operation of seven different applications using different methods in food analysis. The exchange of columns is controlled by the method used. All columns are located in a single Agilent 1290 Infinity II Multicolumn Thermostat. Accordingly, the Agilent 1290 Infinity II Flexible Pump is attached to two external solvent-selection valves for automated solvent switching.
