USE OF JELLY-LIKE EMITTERS IN THE X-RAY-FLUORESCENCE ANALYSIS OF SOLUTIONS

A simple, rapid, and economical method has been proposed for preparing aqueous solutions for X-ray fluorescence analysis. The method consist s in adding dry gelatin or agar to the test solution and forming an el astic jellylike emitter of a specified shape. This method is applicabl e to various calibration procedures (external standard, internal stand ard, and standard-background). The following advantages of jellylike e mitters are demonstrated: uniformity; high quality of the working surf ace; possibilities of analyzing thin or unsaturated layers, suspension s, aqueous solutions of different acidity, and single-phase water-orga nic systems.
