￭ Pump tubing LFL (orange/yellow), 3 stoppers (6.1826.320)
￭ Pump tubing LFL (yellow/yellow), 3 stoppers (6.1826.390)
￭ PEEK capillary, 0.5 mm ID / 1 m (6.1831.060)
￭ PEEK capillary, 0.5 mm ID / 70 cm (6.1831.160)
￭ Pressure screw PVDF (6.2744.000)
￭ Coupling olive/UNF 10/32 (6.2744.030)
￭ Pressure screw, short (6.2744.070)

1 Preparing the pump tubing for the sample
Use the pump tubing with yellow stoppers (6.1826.390) for convey-
ing the sample.
￭ Attach the coupling olive/UNF 10/32 (6.2744.030) to the inlet.
￭ Attach the pump tubing connection with locking nut
(6.2744.160) to the outlet (see chapter "Installing the peristaltic
pump" in the manual for the ion chromatograph or in the man-
ual for the Sample Processor).
2 Preparing the pump tubing for the filtrate
Use the pump tubing with orange/yellow stoppers (6.1826.320) for
conveying the filtrate.
￭ Attach the coupling olive/UNF 10/32 (6.2744.030) to the inlet.
￭ Attach the pump tubing connection with locking nut
(6.2744.160) to the outlet (see chapter "Installing the peristaltic
pump" in the manual for the ion chromatograph or in the man-
ual for the Sample Processor).
3 Connecting the capillaries to the pump tubing for the sample
￭ Tighten the PEEK capillary (6.1831.160) to the inlet of the pump
tubing with yellow stoppers (6.1826.390) using a pressure screw
(6.2744.070).
￭ Tighten the PTFE capillary (6.1803.060) to the outlet of the pump
tubing with yellow stoppers (6.1826.390) using a pressure screw
(6.2744.070).
