What are the steps involved in cleaning the ATR crystal after each sample?

Adding acid to water (not water to acid) is the safer practice when preparing nitric acid solutions.

MP-AES is a technique comparable to traditional [AA] and [AES] but with several potential advantages including lower cost of operation and elimination of the requirement for flammable gasses.

Which solvent has a C=O stretch at a slightly higher frequency than ketones?

For CaCO3 neutralization capacity calculations, which pieces of information are required? (Select ALL that apply)

Isopropanol (IPA) may be used as a cleaning solvent for the ATR crystal between samples.

Your MP-AES result for the diluted run solution is [X] mg/L Ca. The dilution factor from digest to run solution is 250.0. The digest volume is 0.2500 L. Calculate Ca concentration in digest (mg/L) and report mg Ca per tablet represented by the digest. (Report answer to a whole number)
