4.9 Inspecting the Line Filter
Necessary tools
Part Name Quantity Part No.
Wrench (8 mm and 10 mm) 2 086-03002
1
Fix the line filter (A) with a 10 mm
wrench (B) and loosen the male nut (C)
of the pump outlet tube with an 8 mm
wrench (D) to remove it.
2
Pour water into a reservoir bottle and set the flow rate to 1 mL/min.
3
In a no load state, pump water at a rate of 1 mL/min.
• If the pressure is 0.3 MPa or less, it is considered normal.
• If the pressure is more than 0.3 MPa, replace the line filter.
When
a mobile phase additive such as trifluoroacetic acid is used, a ghost peak
may be generated from the line filter. In this case, perform the following
procedure to rinse the line filter.
• Deliver a 17% phosphoric acid solution at a flow rate of 1 mL/min for about
30 minutes. (Pumping pressure: 1 MPa to 5 MPa)
For example, attach a stainless tube with ID0.1 x 2000mm (Part No.:
228-57908-41).
•
Deliver purified water at a flow rate of 10 mL/min for about 30 minutes.
(Pumping pressure: 1 MPa to 5 MPa)
For example, attach a stainless tube with ID0.3 x 2000mm*

*1: Stainless tubing ID0.3 x 1000mm (Part No.: 228-53184-96) 2pc and Coupling
(Part No.: 228-16004-13) 1pc can be substituted.
