At 310° C ion source temperature, the 502 will always be lower than typical. Also - please reduce the quad temperature down to 150° or maybe as high as 165° C... High quad temperature reduces the lifetime of the quad and only very few applications need…
Hi Andreja,
For calculating area % of two different peaks you must set one baseline left and one baseline right from the peaks. Then you have to enable "Information Pane" when clicking "View" in the menu bar and the results are shown as given in the…
Hi,
Yes it is right, please orientate on the last peak before the impurities start.
The exact baseline settings can be seen when enabling the peak information section below the analysis view (highlighted in green):

We were able to configure the plate, we are good for now.
The 1290 Infinity II we have is coupled to Sciex 6500 MS and is controlled by Analyst Software using the Analyst Device Driver.
Hello,
No, you cannot use classic report styles *.frp from Chemstation in the CDS 2.x software. You can use any IR template built in Chemstation in CDS 2.x by copying the .rdl files over to the new project folders.

The software (except for MicroLab Pharma) comes with a 90-day trial period before the software needs to be registered. If you get in contact with our sales team, they should be able to get you a trial copy of the software. Find the appropriate contact…
Hello, Is it possible to get the Intelligent rinse working if the rinses occur after the analysis. Let's say I have 2min analysis time and I changed the Probe rinse of samples and stds to 120s and the Probe rinse 1-3 after the initial rinse. Then the…

A 5% H2 blend should work also. If you're using multiple calibration standards, make sure the range of the standards matches or exceeds the expected range in your samples.
One thing to watch for: I have seen instances where H2 saturates the TCD at high…
