Near real-time fluorescence detection of beryllium

摘要: We report on a fluorescent test for beryllium designed analyzing swipes. The detection is rapid, quantitative and deployable in the field with $5,000 portable fluorimeter. Swipes are placed vial dilution solution added. vials then rotated 30 minutes syringe filtered. An aliquot of 100 pL added to detector fluorescence measured ocean optics unit. can readily detect down 0.02 {micro}g filter paper. Interference studies have been carried out various metals including Al, Fe, Pb, U, Ca, W, Ni, Co Cu. technique has proven be successful under conditions variety surfaces both lab field. It user-friendly, cost effective method.
