How to fix a Waters GCT Premier power switch that won't turn on?
If the power switch fails to power on your Waters Laboratory Equipment, first, unplug the instrument from the main power supply. Then, replace both mains power fuses with the correct type and rating. If the fuses continue to fail, disconnect the instrument from the power supply and contact Waters for further assistance.
Why are the peaks unsteady or low intensity (ion beam) in my Waters GCT Premier?
If you are experiencing unsteady or low-intensity peaks (ion beam) with your Waters Laboratory Equipment, consider these potential solutions: * Troubleshoot the autosampler and check for pressure variations during injection. * Clean the source components. * Ensure that the source voltage read-backs vary with the Tune window setting; if any voltages are absent, disassemble and correctly reassemble the source assembly. * Ensure all Tune window settings are correct, the readbacks are sensible, and that all lens parameters affect the beam. * Ensure the MCP voltage is set correctly.
How do I troubleshoot a non-working source heater in Waters GCT Premier?
If your Waters Laboratory Equipment source heater is not working, inspect the Tune window EI tab Source Temp (°C) readback. A readback of 503 indicates that the source heater is disconnected. Check the integrity of the heater connections.
Why is there no Trap, Emission, or Filament current readback on my Waters GCT Premier?
If you observe no Trap, Emission, or Filament current readback on your Waters Laboratory Equipment, remove the inner source and test the continuity of the filament with a digital multimeter (the resistance should be approximately 0.2 ohm). Replace the filament if it is damaged. If the filament is intact, use tweezers to adjust the spring contacts on the outer source to improve contact. Also, in the MassLynx Tune window, Source tab, click Reset Filament. If the solvent trip level has been exceeded, adjust the solvent trip level or correct the vacuum housing.
What causes no Filament current, Trap current maximum, or Emission current zero in Waters GCT Premier?
If you observe no Filament current, Trap current maximum, or Emission current zero on your Waters Laboratory Equipment, remove the inner source and exit plate. Check the cleanliness of the trap and trap ceramic. Blow out any particles using dry nitrogen.
Why does my Waters GCT Premier Laboratory Equipment have high filament current, high emission current, and low trap current?
If you are experiencing high filament current, high emission current, or low trap current with your Waters Laboratory Equipment, clean the inner source. Also, use tweezers to adjust the spring contacts on the outer source to improve contact. Check the source magnet are attracting.
What causes an inactive ion repeller in EI mode in Waters GCT Premier?
If the ion repeller is inactive in EI mode on your Waters Laboratory Equipment, use tweezers to adjust the spring contacts on the outer source to improve contact.
What does it mean when my Waters GCT Premier Laboratory Equipment tunes with repeller more than 5 V?
If your Waters Laboratory Equipment tunes with repeller more than 5 V, clean the inner source.
What to do if the Emission: Trap ratio is greater than 10:1 on Waters Laboratory Equipment?
If the Emission: Trap ratio is greater than 10:1 in your Waters Laboratory Equipment, remove the outer source magnets and reassemble them with opposite poles facing each other.
How to resolve split peaks on the Peak Display or Spectrum in Waters GCT Premier?
If split peaks are seen on the Peak Display or Spectrum of your Waters Laboratory Equipment, change the TDC trigger threshold (mV) value by 100, within the range 200 to 700 until the peaks are no longer split.
