2 Connect new feedthrough
• Using a wrench or a spanner, unscrew the nut on the interior
side of feedthrough 27 27 and remove the feedthrough.
• Insert new 6.2756.000 tubing feedthrough in the hole and
retighten the nut.
3 Attach tubing to valve A
• Screw 6.1825.210 PEEK sample loop (20 µ L) to connections
"3" and "6" of valve A 18 18 using the enclosed 6.2744.010 PEEK
compression fittings.
• Screw PEEK capillary 19 19 (6.1831.060; L =1 m) to connection
"2" of valve A 18 18 using a 6.2744.010 PEEK compression fit-
ting. Pull the other end of the tubing to the back through the
rear panel opening 41 41.
• Screw PEEK capillary 20 20 (6.1831.040; L =15 cm) to connec-
tion "1" of valve A 18 18 using a 6.2744.010 PEEK compression
fitting.
4 Attach tubing to valve B
• Screw the PEEK capillary 20 20 (6.1831.040; L =15 cm) at-
tached to connection "1" of valve A 18 18 to connection "3" of
valve B 22 22 using a 6.2744.010 PEEK compression fitting.
• Screw PEEK capillary 21 21 (6.1831.040; L =15 cm) to connec-
tions "1" and "2" of valve B 22 22 using two 6.2744.010 PEEK
compression fittings.
• Screw PEEK capillary 25 25 (6.1831.050; L =40 cm) to connec-
tion "4" of valve B 22 22 using a 6.2744.010 PEEK compression
fitting and pull the other end to the front through feedthrough
27 27.
• Screw PEEK capillary 24 24 (6.1831.050; L =40 cm) to connec-
tion "5" of valve B 22 22 using a 6.2744.010 PEEK compression
fitting and pull the other end to the front through feedthrough
27 27.
• Screw PEEK capillary 23 23 (6.1831.050; L =40 cm) to connec-
tion "6" of valve B 22 22 using a 6.2744.010 PEEK compression
fitting and pull the other end to the front through feedthrough
28 28.
