Where to enter sample weights MassHunter V10.1?

Hello, SW: MassHunter Workstation, Quantitative Analysis, Drug Analysis for GC, Version 10.1 Build 10.1.733.0 I am trying to batch process data acquired by GC-FID but I unable to generate the correct sample result since I don't know where to enter the sample weight/concentration. I assume I select type as specimen, enter sample… (Show more Show less)

Hi Rahma05 Do you need to do this on an automated basis. I use the Chemstation version of Open Lab and if you select any two or more results in data analysis and the appropriate report layout you can get this information displayed. Not sure if this helps Kevin

"injectors not detected" and "no injectors" under my loading method

Hi guys, when I tried to run my sequence in GC-FID, the workstation showed "front injectors not detected", and under my method, the configuration showed no injectors. However, the parameters I entered for injection could be found in the GC (7890A) operation panel. I am wondering how to fix it. Please give me some hints under such a circumstance.… (Show more Show less)

The chromatogram above looks like the built-in Test Plot. Open GC Parameters and select the Signals section. Make sure that the selected signal is "Front Signal (FID)" or "Back Signal (FID)" on the Signal Source dropdown. Also, data rate for FID is typically 10-20 Hz.

Retention time problem

Good morning, we have a GC-MS with a DB-HeavyWax Column. Yesterday we changed the column for a new one (the same). The retention times of our samples shifted 8-11 min. Now, the peaks appear 8-11 min later. We are using a flow of 1.8 mL/min, if we try to do a retention lock, the pressure would be so high. The new column is the same model as the… (Show more Show less)

Hi, As I already mentioned before, I'm not a wiz at GC. I just try to read a lot. I do have retention times shift during my injections but this is due to a slow degradation of the column because of the type of compounds injected. When I change column, the retention times are completely off. It is not worrying because the relative retention…

Problems with reprocessing

Hello, I use OpenLab CDS C 01.08, I have problems when reprocessing the sequence, it accepts the changes I make, but when generating the report the previous values of the sequence appear. This problem only happens to me in some sequences.

What are the best practice to run Mercury on ICPMS

Hello It has been observed sometime that while working on ICPMS, not getting good linearity of mercury. SO, what are the best practice follow to prepare the mercury standards (calibration points) and rinsing solution. Is gold mandatory to add into the rinsing solution , if we are plotting linearity from 0.1 ppb to 5 ppb Regards Vinay
