This is a very primitive exact mass calculator. Given the formula of a chemical species, the calculator determines the exact mass of a single isotope of that species and the relative abundance of that isotope. The isotope selected has the property that each atom in the species is the most ab...

Two digital ratio-measuring systems have been designed for use with a double collector isotope ratio mass spectrometer. Both systems are interfaced to a programmable calculator for data acquisition and processing. This provides a dedicated on-line system suitable for both "delta" and "enrichment" ...
