IC equipment: Inline-Ultrafiltration

￭ 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)

￭ Pump tubing connection with locking nut (6.2744.160)

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).

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).

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).
