SCREEN (see Section C.9.6) displays the number of cycles performed since the
assembly was last replaced.
Two versions of the PEEK sampling needle assembly are available. The version
used depends on the volume of the sample syringe installed:
• If the sample syringe is 1 mL or less, a 1.2 mL sampling needle assembly
(P/N 054271) is installed (see Figure 5-8
).
• If the sample syringe is 5 or 10 mL, an 8.5 mL sampling needle assembly
(P/N 061267) is installed. The 8.5 mL assembly includes the same parts as the
1.2 mL assembly, plus a coupler and an additional length of tubing to increase
the volume (see Figure 5-9
).
NOTE The PEEK sampling needle assemblies use a different
bolt and ferrule than previous sampling needle
assemblies. If you remove the PEEK needle from the
0.8-mm (0.032-in) ID tubing, be sure to use the correct
fitting bolt (P/N 052667) and ferrule (P/N 064553) to
reattach the needle to the tubing.
