Hi,
rinsing with a higher concentration of HNO3 sounds like a plan
you could try to sonicate the T-Piece where the istd is connected. Often this is a source for contamination. Anyway the Pb is not a problem in this low concentration. And your main…
That video is a bit hard to see. There's no visual evidence of overheating nor staining on the rest of the analyzer/quad radiator. The factory gold is not a separate applied foil. That needs further investigation. I would recommend contacting Agilent…
Hello,
I am not entirely clear on what you are doing as well. Below is an example of how I would do a % recovery from an existing standard injection in the result set. The calculation would pull the theoretical value (Compund_CalibrationAmount) from…
Hi JONHY , thanks for your question.
I’ve used an online tool to translate your post. English is the official language of the Agilent Community, and the platform does not support translating a post from local language to English. You can view pages…
Hello,
I think there are other posts where I go over this in more detail. If you want to do a recovery or check calculation for more than one compound and it is not a reinjection of a standard level or the standards are not in the results set, the…
Hello,
Yes, that will not work. You need to test the length of the name as I said in the previous response. See the example below the unknowns have a low value of 1.56.
if(LEN(Compound_Name)>0, getconstant(“Relative response factor”),0.98)

UV-Vis spectroscopy is a well-established technique in many laboratories. For decades, laboratories have adapted to pain points associated with UV-Vis workflows such as daily instrument warm-up, yearly lamp replacement, and slow and cumbersome temperature…
