Abstract
A simplified flame accessory for Beckman spectrophotometers embodies a miniature one-piece burner-atomizer combination which sprays small samples directly into an oxygen-acetylene or oxygen-hydrogen flame. Glass construction, with palladium capillary, permits several structural simplifications. The instrument provides exceptionally rapid reading without difficulty from drift, contamination, warm-up requirement, or clogging. Precision is better than one-half percent and calibration is held from day to day. Any liquid of viscosity up to several centipoises can be analyzed, and there is no limit on solute concentration. The hotter flame gives improved detection limits for many metals. An outstanding example is the determination of lead in gasoline. A revised and enlarged tabulation of flame spectra is given. Analytical procedures and interferences are discussed.
