BeFinder® is an optical fluorescence method of detecting beryllium. Beryllium from the sample is dissolved in aqueous ammonium bifluoride to which a dye solution is added and the fluorescence measured.

The sample preparation and measurement can be done manually or in an automated mode (also called High Throughput System).

BeFinder® is suitable for measuring the most stringent requirements and beryllium can be quantified starting from 0.005 micrograms on the media. This can be used for wipe, air and bulk samples.

BeFinder® is compatible with the following approved test methods:

• NIOSH Analytical Methods
       BERYLLIUM in Air by Field-Portable Fluorometry, Method 7704
       BERYLLIUM in Surface Wipes by Field-Portable Fluorometry, Method 9110
• ASTM D7202 Method
  Standard Test Method for Determination of Beryllium in the Workplace Using Field-Based Extraction and Fluorescence Detection.
  
• ASTM D7458
  Standard Test Method for Determination of Beryllium in Soil, Rock, Sediment, and Fly Ash Using Ammonium Bifluoride Extraction and Fluorescence Detection.
  

BeFinder® meets all current and proposed requirements by:

• DOE
• OSHA
• NIOSH
• ACGIH
