Thank you very much.
We actually monitor mass 56 (among with others) at the beginning of each session because mass 56 counts start at around 30-70 K (skipping warm up, just when the plasma lights up) and go down till ~500 counts in around 20-40 minutes…
For WinUV 5.1.3.1042 SCM has an E-sign option, which says to go to the profile screen which does not have 'Authorize Worksheet' and 'Review Worksheet' Privileges to select….Kind of a wild goosechase.
Click 'Configuration > Electronic Signature' to access…
Here are the services I suspect are not running after your last reboot. Another reason is that the graphing options are available and graphics and annotation are not from the SDA.
Hello,
Thanks for your reply.
I tried the Area Sum option, it works indeed as areas for all transitions are summed, but the chromatograms are still separated for every transition, and thus my S/N is not better. Same thing for the group function, I…
In Agilent GPC/SEC software it is the Coefficient of Determination that can be interpreted as correlation coefficient (r) and this is the parameter that we use to measure the "goodness " of fit.
We have 6546 QTOF in house, however the ion counts of the samples are very low. It is a new instrument and I am expecting E7-E8 signal intensity. Any thoughts here?.
Thanks for the feedback. We were looking at the glass wool with unpacked liner tubes as the cost is greatly different. However when observing how well a prepacked liner compares to one of our techs liners, they look not as secured or dense opposed to…
The mass calibration/check for the quadrupole is failing across all isolation widths. Mass delta on 322m/z exceeds limits.
We system tuned a few weeks ago. Can someone please outline the troubleshooting workflow for this type of issue (where to start…
