Answer

• Procedure to follow for Analyst® software:

1) Enable "MS only" hardware profile.
2) Use Tune and Calibrate mode.
3) Create a generic MRM method following a random transition. Allow enough time (10 min) to give the heaters time to heat up.
4) Put a source temperature (TEM) of 700°C. Below 700°C the heaters do not redden.
5) Put a 70 psi GS2 to protect the heaters when using high temperatures.
6) Click on Start.
7) Check if the heaters are reddening. If they don't turn in red, there is an issue with it and you should contact SciexNow.


 

• Procedure to follow for SCIEX OS software:

1) Enable "MS only" hardware profile.
2) In the SCIEX OS menu select MS method.
3) Click new and create a generic MRM or MRMHR method following a random transition. Allow enough time (10 min) to give the heaters time to heat up.
4) Put a source temperature (TEM) of 700°C. Below 700°C the heaters do not redden.
5) Put a 70 psi GS2 to protect the heaters when using high temperatures.
6) Click on Start
7) Check if the heaters are reddening. If they don't turn in red, there is an issue with it and you should contact SciexNow.

• Example of heaters that turn red:

If you have any doubt, send a photo of the heaters in these conditions (TEM = 700°C and GS2 = 70 psi) to sciexnow@sciex.com
