摘要:

Emission spectra of water samples stored in polyethylene botles show the pressence of impurities whose concentration roughly parallels the length of storage. With excitation at 280 nm, water stored for 3 months in polyethylene gave a blank signal equivalent to the emission of 10−7Mbovine serum albumin. Caution should be exercised in using plastic bottles for fluorometric reagents.
