ACQUITY TUV/PDA "Filter initialization failure" - WKB67475

SYMPTOMS

• Filter initialization failure during wavelength calibration
• Grating initialization failure during start-up

ENVIRONMENT

• Empower
• ACQUITY UPLC PDA Detector
• ACQUITY UPLC Tunable UV Detector
• 2996 PDA Detector
• 2998 Photodiode Array Detector
• 2489 UV/Vis Detector
• 2487 Dual-wavelength Absorbance Detector

CAUSE

Dirty, contaminated, or defective flow cell

FIX or WORKAROUND

1. Flush the flow cell with aqueous solvent (back flushing at low flow rate may be necessary)
2. After aqueous wash, clean flow cell with 25:25:25:25, Water:Methanol:Acetonitrile:Isopropyl alcohol
3. Verify functionality or replace flow cell as a billable consumable
