Mass spectrometry of metal chelates-I Detection on the picogram scale.
A method has been developed for the detection and estimation of metals in the form of chelates in amounts down to 10(-12) g. The chelate is evaporated into the source of a mass spectrometer and a continuous record of the ion current at a significant mass number is made. The integrated ion current is directly proportional to the concentration of metal chelate.
