the new

BECKMAN Flame PHOTOMETER Flame Photometer

with DU Spectrophotometer

attached.

A valuable aid to a wide variety of analytical problems, including water analysis, metal and ore analysis, determination of inorganic traces and impurities in foods, chemicals, biologicals and pharmaceuticals.

The instrument provides high sensitivity for determination of very small traces of elements. High resolving power and photometric accuracy of the Reckman Spectrophotometer eliminates interference from other elements and background illumination from the flame.

QUICKLY ATTACHED TO THE

The present users of the Reckman Model DU Spectrophotometer are familiar with its numer­ ous fine features. In order to use this Flame Photometer with the DU Spectrophotometer, it is only necessary to remove the lamp housing and place the burner near the light entrance. Control valve and gauges are all conveniently mounted on the control panel, the base of which provides a mount for the Spectrophotometer. The special burner is water cooled and is vented through a water-cooled chimney.

MODEL DU QUARTZ SPECTROPHOTOMETER Samples in solutions are atomized in a spe­ cially designed sprayer and introduced into the hot oxygen-gas flame to excite the spectral lines of the chemical elements. The Spectrophotometer isolates these lines and measures their intensities relative to a blank or standard. Results are read directly on an accurately calibrated dial. Sample consumption rate is less than .2 cc. per minute. Complete analysis can be made on samples as small as 5 cc. Samples can be analyzed very rapidly, a rate of four samples per minute being maintained easily.
