Abstract
A low-cost practical method of determining beryllium or a beryllium compound thereof in a sample is disclosed by measuring fluorescence. This method discloses optical filters for use with low cost fluorometers which may be used to quantitatively determine the presence of beryllium. This method may be extended to estimate particle size distribution for particles comprising Beryllium. A method is also disclosed to store solutions for extended period of time so that these materials are stable during transportation and in the labs.
