In the earlier 2 posts, I have discussed about 1. The merits of automated sampling and 2. Validation of automated dissolution system . Thank you for giving our team warm response for these blogs. We received many queries regarding automated sampling on…
Hi Lisandro,
if your analysis looks fine, go for it. The mentioned increase in off-mass background can affect your signals (not predictable) on other masses, as it is electrical noise.

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…
