“…Since the quantity of sample removed for analyses is very small with respect to the total volume of the sample, the volume changes are neglected. For example, ten 5-µ1 additions would be required to cause a 1% volume change in the 5-ml solutions, while the agreement between injections has been reported to be within 2-10% for HVAA measurements as shown by our own work and others (23,26,39,40).…”

“…This technique is more sensitive than flame techniques for most elements and it can readily be adapted to the direct analysis of metals in many matrices (20)(21)(22)(23)(24)(25). The application of HVAA to the determination of trace metals in petroleum has recently been reviewed (26). Several applications of HVAA to the determination of trace quantities of manganese in fresh water have been reported (27)(28)(29).…”

A method is described for the determination of manganese by heated vaporization atomic absorption which is capable of measuring manganese directly in petroleum matrices in concentrations from 10-300 ng of manganese per gram of sample. The technique of micro standard additions is used to overcome matrix effects. A discussion of heated vaporization atomic absorption as related to the characteristics of a Varían Techtron Model 63 Carbon Rod Atomizer is included. The precision of the method is calculated from data obtained using this method at different laboratories.

“…The lower signals obtained from organic solvents for the same amount of beryllium were not fully investigated; however, it is postulated that the effect is due to spreading of the organic solvent on the surface of the furnace. Acid and solvent effects have been reported in other HVAA analyses (15,34).…”
