Slide-rule for atomic-absorption flame photometry.
A new slide-rule is described for calculations in the field of atomic-absorption flame photometry. Most of the quantities used in analytical applications and in studies on the analytical behaviour of determinants are included in the operations which may be performed with the slide-rule. It can also be used for the most common operations necessary for calculation of concentrations, dilutions, dilution ratios and analytical factors. The rule described quickens calculation and reduces use of conversion tables.
