4 Settings at the 766 IC Sample Processor

• For operation with the 790 Personal IC it is recommended

that the following program "790" is used with the 766 IC

Sample Processor:

(entire sample rack)


− Initialize remote interface


− Waiting until 790 Personal IC sends

signal on remote line 3

− Move needle to sample position

− Place lift with needle to working

position

− Waiting until 790 Personal IC sends

signal on remote line 3

− Fill sample loop with sample during

120 s


− Settings for changer functions




− Reaction to manual stop

5 Settings in the «790 Personal IC» program

• A time program must be drawn up for the selected system

which first produces an impulse at remote lead 3 to start

sample changing on the 766 IC Sample Processor and then

switches the injection valve to the "Fill" position. A further im-

pulse is then produced to start filling the sample loop within

120 s. At the end, the injection valve is switched to the "Inject"

position, which also starts data acquisition.
