Abstract

Measurements of characteristic masses for Ag, Cd, Cr, Ga, Ge, and In have been made over a broad temperature range. The experimental results show that the experimental values of <i>m</i>₀ have appeared to be stable to better than 10-15% when the analytes are atomized in the temperature ranges studied. Influences of atomization temperatures on the ratio <i>m</i>₀(calc)/<i>m</i>₀(exp) were studied when the analytes were evaporated from the wall, with the use of the platform and the V-shaped boat techniques. For Ag and Cd the ratio <i>m</i>₀ (calc)/<i>m</i>₀(exp) does not change significantly, and their values appeared to be nearly 100% in the temperature ranges studied when the analytes were evaporated with the use of the platform and the V-shaped boat techniques. However, for the remaining four elements (Cr, Ga, Ge, and In) the ratio <i>m</i>₀(calc)/<i>m</i>₀(exp) increases with the rise of atomization temperatures, and their values appear to be only about 20-50% in the absence of a matrix modifier. However, the ratio <i>m</i>₀(calc)/<i>m</i>₀(exp) is obviously increased in the presence of a matrix modifier.
