Routine Maintenance
The 2998 PDA detector requires minimal routine maintenance.
To achieve optimal performance, follow these steps:
1. Replace solvent reservoir filters in your HPLC system regularly.
2. Filter and degas solvents to prolong column life, reduce pressure
fluctuations, and decrease baseline noise.
3. Flush buffered mobile phases out of the detector with HPLC-grade
water followed by a 5 to 10% methanol solution each time the detector is
shut down. This process prevents:
•
Plugging of the solvent lines and flow cell
• Damage to the components
• Microbial growth
Warning:
Avoid electric shock:
• Do not open the detector cover. The detector does not contain
user-serviceable components.
• Power-off and unplug the detector before performing any
maintenance on the instrument.
Caution:
To avoid damaging electrical parts, never disconnect an
electrical assembly while power is applied to the detector. To interrupt
power to the detector, set the power switch to Off, and then unplug the
power cord from the AC outlet. Wait 10 seconds before you disconnect an
assembly.
