Why does a TempGuard message appear during a run on my CEM MARSXpress Plus?
If a TempGuard message appears during a run with your CEM Laboratory Equipment, it could be because some vessels are hotter than others. Also, avoid mixing old and new liners; run them in separate turntables.
Why is my CEM MARSXpress Plus Laboratory Equipment experiencing excessive venting?
If your CEM Laboratory Equipment experiences excessive venting, it could be due to several reasons. First, check that the "Sample Type” selected in the method is correct; “Organic” is recommended for most samples. Also, ensure the vessel plug is correctly placed on top of the liner before securing it with the cap. Finally, verify that the vessels are properly torqued using the provided torque tool.
What to do if I see uneven bar graphs during a run with my CEM Laboratory Equipment?
Uneven bar graphs during a run with your CEM Laboratory Equipment can be caused by several factors. Ensure that the samples have similar properties and weights, or use the same sample in all vessels with similar amounts. Also, make sure you're using the same acid(s) and acid volume in each vessel. Finally, consider that some vessels might be hotter than others. Also, consider that some vessels may contain acid blanks.
How to address sleeve appearance changes in CEM MARSXpress Plus Laboratory Equipment?
If the sleeve of your CEM Laboratory Equipment has turned white or is stained on the ends, replace it. To prevent sleeve damage, avoid high temperatures for extended periods. If the sleeve comes into contact with acid, wipe it with a damp cloth and allow it to dry.
