Hi all - I am brand new to running ICP-OES and have a question about the instrument Calibration function. My instrument is set up to run organic samples and we do not have torches or spray chamber to hand aqueous samples. The only information I can find about preparing the standard needed to run the Instrument Calibration says to prepare the sample as aqueous with Nitric Acid. I don't want to assume I can prep the standards with the same concentrations as listed under ICP-Expert Help function, but in mineral oil/toluene (how our samples are prepped). Any users out there that run their ICP as organics only and preformed this instrument calibration that can help me out?
