How do you split the sample? Is it two different injection ports? Two different columns into the injection port? Or a two way splitter - purged or unpurged?
Are you injecting split or splitless? Please upload the acqmeth.txt file that is in Windows…
Hello,
Error 1213 typically comes with other errors that truly describe the issue, like the 2150 error you are getting.
First, check the cone orifices. Use a microscope or powerful magnifying glass. If they are clogged or salted over, clean. The opening…
This may be due to several factors. First of all, make sure that all plasma monitor connections and cables are properly connected and not damaged. Also check that there is sufficient gas flow (eg argon) to maintain the plasma. Check the cleanliness and…
Hello all,
I´m facing a Silicium contamination in ICP-MS analysis, I have used a 7800 ICP-MS.
I have digested my samples with HF, HCL and HNO3 and neutralized it with boric acid, after the analysis I have Silicium CPS has increased around 30%.

Hi Layden,
your source has died (normal ratio Amps/Volts should be starting at 1.9/2.7). Each year you will find a decline in Amps until it has reached 1.6, then it will give a red bar. In your case it's 0, so the filament is probably broken - your…
I have almost the same system as shown in the picture for over a year now. The application was supplied by Da Vinci Laboratory Solutions in the Netherlands. It is a Mettler TGA 2, with a Gerstel MPS autosampler on a Agilent GCMS(MS) with a CIS injector…
Thank you. I contacted the support. I just had to login into agilent subscribenet and download the latest version after entering the authorization key.
Hello,
That looks like a standard IS calibration using area percent. The purity of the standard can be entered as the compound multiplier. I would start by searching the help for calibration, internal standard, and mass percent calculations. You can…
