Fundamentals of the instrument dialog
Main menu Each key of the 732 IC Detector opens a main menu
whose thematically arranged submenus can be se-
lected by repeated pressing of this key. The name of the
key always appears in the top line of the display.
Submenu Each submenu has a title which is marked by " > " and
appears in the bottom line of the display. <ENTER> is
used to move from the title to the individual inquiries
where the most important settings of the instrument can
be changed. <QUIT> effects a return to the standby
mode of the instrument.
Inquiries With inquiries without " : " the valves must be entered
using the numeric keys. The inputted value is accepted
with <ENTER> and the next inquiry appears.
In the case of inquiries with
" : " the admissible values
must be selected using the <SELECT> key. The set
value is accepted with <ENTER> and the next inquiry
appears.
Depending on the parameter, <CLEAR> is used to
reset the displayed value to the smallest possible value
or the default value. The <CLEAR> key is also used to
abort wrong entries.
<QUIT> is used to quit the inquiries and return to the
title of the submenu.
7 Enter parameters for the conductivity detector
PARAM
⇒ Press the <PARAM> key to open the main menu for the
parameter settings.
PARAM
>PARAM/detector
The title of the submenu "d etector " appears that contains
various inquires for the conductivity detector.
ENTER
⇒ Press the <ENTER> key to move to the inquiries.
>PARAM/detector
range: 1.00 mS/cm
The first inquiry shows the measuring range for which 7
stages from 0 … 100 µ S/cm to 0 … 10 mS/cm are available.
Select the measuring range to ensure that the conductivity
value of the eluent used easily lies within the selected
range.
SELECT
⇒ Press the <SELECT> key until the desired measuring
range appears in the display.
>PARAM/detector
range: 200
µµS/cm
The eluent used for the PRP-X100 Anion Column has a
conductivity of ca. 150 µ S/cm. A range of 200 µ S/cm is thus
selected as the measuring range.
