What to do if gas flow is lower than the set point in Buchi Security Sensors?
If the gas flow is lower than the set point, the gas supply valve might be closed. Open the gas supply valve. The gas supply could be low or empty, so check it and replace if necessary. There may also be a blockage or leaks in the gas line before the detector; check the gas line for blockage and leaks, and remedy or replace as necessary.
What causes no gas flow in Buchi Security Sensors?
If there is no gas flow, the gas source valve may be closed. Open the gas valve. The source gas pressure might be too low; adjust the source pressure to 65-80psig. The gas source may also be low or empty; replace the gas source.
What to do if gas pressure is too low in Buchi Alltech 3300 ELSD?
If the gas pressure is too low, the gas source may be low or empty; check the gas source and replace if necessary. The regulator pressure may be too low; adjust the regulator pressure to 65-80psig. Gas leaks may be present before the nebulizer; check gas connections for leaks and tighten fittings if necessary.
How to fix unstable gas flow in Buchi Alltech 3300 ELSD?
To fix unstable gas flow, check the stability of the gas source and remedy if necessary. The nebulizer may be blocked, so clean or replace it.
Why is the gas pressure too high in my Buchi Alltech 3300 ELSD?
If the gas pressure is too high, the nebulizer may be blocked. Clean the nebulizer.
Why is inlet gas pressure low in Buchi Security Sensors?
If the inlet gas pressure is low, the regulator pressure setting may be too low; adjust regulator pressure to 65-80psig. The gas source may be low or empty; replace gas source if necessary.
What causes spiking in Buchi Security Sensors?
Spiking can be caused by several factors: 1. Drift tube temperature and/or gas flow rate set too low. Re-optimize the drift tube temperature and gas flow rate following the optimization procedure. 2. Gas source contaminated or low purity. Use clean, dry, inert gas, usually 99.9% pure nitrogen. 3. Mobile phase contaminated or made of low quality material. Replace with fresh, filtered, higher-quality mobile phase. 4. Nebulizer, drift tube, and/or optical cell dirty. 5. Improper nebulization. The nebulizer may be partially obstructed.
What causes gas flow error in Buchi Alltech 3300 ELSD?
A gas flow error can be caused by several issues. The gas source may be low or empty, so check it and replace if necessary. The regulator pressure setting might be too low; adjust regulator pressure to 65-80psig. The nebulizer may be blocked, so clean it.
What does baseline drift mean in Buchi Alltech 3300 ELSD?
Baseline drift means that the detector has not fully equilibrated. Wait for detector to fully equilibrate.
What to do if Buchi Alltech 3300 ELSD Security Sensors fail?
If the detector fails, it might be in Standby mode. Put the detector in Run mode, allow it to equilibrate, and then repeat the test. The detector might also still be equilibrating, so wait for it to equilibrate and then repeat the test.
