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…

Hello jeremy_lai ,
In your latest expression you have removed the first check to see if there is a qualifier peak present. You need to change your first if statement to read as you had it in your previous post.
if BoundItems[“QualifierPeak”] is None…
Hello Yasar ,
To switch from an MRM method to dMRM in acquisition you must have acquired an MRM data file that can be successfully processed in Quant. If for whatever reason the data file cannot be processed in Quant, then you will receive the error…
