When attempting to submit a sequence in EZChrom, it fails to submit and returns this error message:
This happens each time a sequence is submitted. Any help would be appreciated!
It seems that analysts have access to all method versions saved. Is there a way to Analysts them only have access to method versions that are approved?
Hello,
I'm about to replace the nitrogen tank that feeds the collision cell on our 6545 QTOF. I just have a simple question, can I change the nitrogen tank while the MS is in stand-by mode or does it need to be vented ?
This brings me to a second…
Hello Marty,
Thank you very much for your prompt and informative responce. I've viewed the video and immedeatly have made coressponding changes in my report template. This is exaclty what I was looking for. Now, I can use one template for different…
Hi LD,
You are very welcome! Our protocol recommends using 95% ethanol (do not use 100 % ethanol as it contains traces of benzene, which is detrimental to mitochondrial function) rather than DMSO. Also be sure not to add ethanol to the injection ports…
Hello strader.kh ,
If you are using Excel report templates you must generate the report.results.xml file to get a report.
If you are not using Excel templates you can disable the generation of this file in the Results tab of the Report Method Editor…
Hello,
What software and version are you using? I would assume it is OpenLab CDS 2.x, either workstation plus or a client server system. If you have one of these systems, it is possible to get orphaned IDs in the database, which can stop the system…
