Hello bofzgi84 ,
As an update to this, a colleague of mine has pointed out that for LC data the Compound ion count threshold settings are not present. I took the above screenshot with no data file loaded, so all possible options were enabled. I can…
Was the air/water check before you changed the septum and liner acceptable? 60% Oxygen...what is the Nitrogen percentage? 60% Oxygen would either be a gigantic leak and the Nitrogen percentage will be off the charts, or there is oxygen in the carrier…
Hi ,
I have try the method (Isocratic) on the different lines (A,B,C,D) and compare the results . It appear that there was a difference (shift in retention time about 2 mins) in the result were line (A) is used in the method . Thus the problem might…
Dissolution testing is labor intensive as well as a technique and time dependent analytical procedure. A typical dissolution workflow consists of several steps including dissolution media preparation, media filling, introducing the dosage form into the…
Hello all, What is the difference between the IntelliQuant / no IntelliQuant mode in SemiQuant (QuickScan) ? When I activate this option, the LOQ are modified.
In IntelliQuant mode, the LOQ is calculated according to TDS in sample ? Thanks in advance…
