2 To Detector
• Use another piece of 6.1831.010 PEEK Capillary (i.d. =
0.25 mm, o.d. = 1/16"), further 6.2744.010 Pressure
screws and a 6.2744.040 Coupling (all included in
standard equipment) to connect the outlet of the 828 IC Dual
Suppressor "To Detector" 7 with the inlet of the conductivity
detector in the 761 Compact IC.
3 Detector outlet
• Mount the 6.1803.090 PTFE Capillary (i.d. = 1/16", o.d. =
0.25 mm, 15 m) as a backpressure capillary between the
detector outlet and the waste container. Use a 6.2744.010
Pressure screw and a 6.2744.040 Coupling (all included in
standard equipment) for this.
The backpressure capillary is required to ensure the correct ratio
between the flow rates at the outlets of the suppressor cell, see
Section 3.5.
Check this ratio the
first time that a system in which the 828 IC Dual
Suppressor has been newly installed is started up; a detailed
description is given in Section 3.5.1.
4 To Waste
• Connect outlet "Waste" 12 of the 828 IC Dual Suppressor to a
waste container. Use the 6.1803.020 PTFE Tubing (i.d. =
0.97 mm, o.d. = 1.57 mm) and a 6.2744.010 Pressure
screw (both included in standard equipment) for this.
PEEK capillaries that are to be provided with new connections must
have a perfect and plane cutting surface. This is best obtained by
using the optionally available 6.2621.080 Capillary cutter .
2.5.3 Settings for control by the 761 PC Software 1.1
On the 828 IC Dual Suppressor switch remote switch 15 to "ON" and
also switch mains switch 16 to "ON". The Dual Suppressor can now
be controlled by an external instrument.
In the 761 PC Software 1.1 you must make the following settings:
• Start the 761 PC Software 1.1 and select your system.
