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…

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…
