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…
1 uL is injected for PAH.
We do change the liner often and are using the one from all the app notes (with glass wool). We haven't tried a dimpled but do use a dimpled with the PBDE method.
After doing a bunch of troubleshooting over the last few…
I'd like to bump this thread up to the top because in our lab we have had the same problem, and our amazing IT guy was able to solve it!
It turned out that on the PC where the Data Analysis (same version as olabanalyst ) was faulty, it had been installed…
Hi everyone. There are some doubts that I would like to clarify because we're experiencing some drift and sensitivity problems and it may help.
We've already cleaned the cones, lenses and sample introduction system, including the torch.
1) There is…
The peak to the left in the Lithium window is Li6. This is from internal standard solution. Li6 abundance is typically very low and should not be larger than the Li7 peak. When you run start the plasma, is the internal standard (ISTD) line in a nitric…
