Why is the retention time shortening in my Jasco Water Pump?
Shortening retention time in your Jasco Water Pump can be attributed to column deterioration; consider replacing the column. Variation in ambient temperature can also affect retention time; protect the column using thermal insulation. Another cause can be variation in eluent composition; prepare the eluent again.
Why is the retention time lengthening in my Jasco Water Pump?
Lengthening retention time in your Jasco Water Pump can occur due to a decrease in the actual flow rate; see Section 2.1.2 for details. Insufficient column re-equilibration can also cause this; increase the column re-equilibration time. Variations in ambient temperature can affect retention time; protect the column using thermal insulation. Changes in eluent composition can also contribute; prepare the eluent again.
Why does Jasco Water Pump have spike-shaped baseline noise?
If you observe spike-shaped baseline noise in your Jasco Water Pump, it could be due to bubbles in the cell, which causes noise toward increasing absorption; refer to the maintenance manual for the UV detector. Another cause could be electrical noise; in this case, ground the instrument.
Why is the bottom panel drain port of my Jasco PU-1580 leaking?
If the bottom panel drain port of your Jasco Water Pump is leaking, it could be due to deterioration of the diaphragm on the plunger washing mechanism; in this case, replace the diaphragm. Alternatively, it may be due to leakage from the plunger seal. If the head mount flange hole is clogged, solvent will leak from the drain hole.
Why does my Jasco PU-1580 Water Pump have high baseline noise?
High baseline noise in your Jasco Water Pump can stem from several causes. Variations in pump pressure can contribute to baseline noise; see Section 2.1.3 for related information. Mixing noise, especially when running a gradient program or using a post-column derivatization system, can also cause this issue; consider adding an extra mixer or damper to the pump. Detector cell problems like bubbles, contamination, or leakage can also lead to high baseline noise; refer to the maintenance manual of the UV detector. A decrease in the light intensity of the detector, due to light source or mirror deterioration, can also cause this issue; refer to the maintenance manual of the UV detector.
What to do if Jasco PU-1580 Water Pump shows TROUBLE UNDER PRESS errors?
If the Jasco Water Pump experiences 'TROUBLE UNDER PRESS' errors, it might be due to air bubbles in the pump head. To resolve this, open the purge valve to remove the air bubbles. Another cause could be a clogged inlet filter, especially if using buffer solutions; in this case, replace the inlet filter. Also, check for a leaking plunger seal and tighten the pump head securing screws. If leaking continues, replace the plunger seal. A leaking inlet tube fitting can also cause this issue; tighten the fitting. In some cases, the pump head might be deteriorating, requiring thorough cleaning with an acid or alkaline solution. If the leak occurs at the downstream side of the pump, refer to the appropriate manual.
