What to do if autotune fails after running for a while on Thermo Scientific Laboratory Equipment?
- A
  adamsmichaelJul 25, 2025
  If the Thermo Scientific Laboratory Equipment system fails autotune with a message indicating a spray stability check failure, examine the liquid connections for any leaks. Also, ensure that the electrospray needle is correctly adjusted. Unstable flow rates from the liquid pump can also cause this; AXP pumps need high back pressures for stable flow, so install backpressure coils between the pump and the instrument.

Why does autotune fail at the beginning on Thermo Scientific Laboratory Equipment?
- L
  Lance RogersJul 31, 2025
  Autotune may fail at the beginning if the chromatograph is not set to 50 µL/min. Without sufficient liquid flow from the chromatograph, the calibrant won't be pushed into the ion source, causing the autotune to fail.

What to do if the reference solution does not stop flowing after fill time in Thermo Scientific Laboratory Equipment?
- D
  Daniel RussellAug 4, 2025
  If the reference solution continues to flow after the fill time in your Thermo Scientific Laboratory Equipment, it might be due to the bottle not depressurizing because the frit on the valve of the calibrant delivery system is clogged. This valve is located on the gas control module under the main power supply inside the instrument. Alternatively, the waste line may be inserted too far down the drain tube, causing a siphoning effect.

What to do if reference solution is not flowing down the drain during fill time in Thermo Scientific Laboratory Equipment?

  Krista ReidAug 9, 2025
  If the reference solution isn't flowing down the drain or is flowing too slowly during fill time on your Thermo Scientific Laboratory Equipment, check the clear plastic pressurization line, green PEEK, or calibrant loop for kinks. Also, verify that the ferrules on the green PEEK tubing are not overtightened.

  If the reference solution isn't flowing down the drain during fill time for your Thermo Scientific Laboratory Equipment, try replacing the calibrant bottle. Ensure the tubing's position is near the bottom of the bottle, but not touching it, to avoid picking up particulates that could cause clogging. Also, confirm that there is nitrogen supply to the instrument.
