remaining to the end of the process. The status and total remaining time are also shown in the main
display. With the function buttons the three main displays STATUS, EXTRACTION and MENU are
accessible.
B STATUS shows a diagram of the lines, valves, solvent reservoirs, extraction cells, and collection vials
of the instrument. The valves open and close according to the stage of the method and the num-

also includes two functions that are required prior to operation: activation of the extraction positions
(OCCUPIED POSITIONS) and preheating of the instrument to the operating temperature (PRE-
HEAT).
