Abstract:

Calcium is reported to be the element most frequently determined by atomic absorption, and the nitrous oxide–acetylene flame is recommended for this determination. We wish to point out a condition in which the strong calcium atomic emission from this high temperature flame markedly reduces the sensitivity of the atomic absorption determination and causes bending of the absorption analytical curve.
