I tried running the Debugging script with the newest version of Visual Studio (2022) and IronPhython (3.4). It does not work.
It doesn't seem like newer versions of Microsoft Visual Studio (2022) work with older versions of IronPython (eg., 2.7.5).…
Using Windows Explorer, underneath your run method's subdirectory is a file called ACQMETH.TXT. Please copy and paste the contents of that file here and we can go over the run parameters.
Do you have a very stable standard to run to ensure your system…
Hello,
That looks like Chemstation in the integrator preview window can you relay the version and confirm the table captured. If that is the case these are preliminary results from the integrator preview for final values, I would look at the reports…

GC Septum
Inlet septa are used to maintain a leak-free seal at the GC inlet, even after repeated injections.
If the septum has a dimple, the dimple…
Modern labs are constantly looking for opportunities to improve their efficiency and reduce the workload of their staff. Automating repetitive tasks can help to maximize instrument usage and free up operators to perform other tasks, improving overall…
Unless you are strictly matrix matching your calibration standards to your samples, it is best to use an internal standard to account for matrix effects. This is standard practice in ICP-OES. Most people use Yttrium or Scandium, an element that is not…
