WebGeneral description. Method: photometric 0.05 - 2.00 mg/l MBAS Spectroquant ®. The method is analogous to EPA 425.1, APHA 5540 C, ASTM 2330-02, ISO 7875-1, and DIN EN 903. This Spectroquant ® Surfactants (anionic) Cell Test allows the determination anionic surfactants (hydrophilic end carries a negative charge) in water samples. Webphotometer (Sigma ZFP 22). We used the OD at 334 nm minus the OD at 405 nm and an extinc- tion coefficient of 6190 OD L tool -1. Methods ... (1989). Five /zL of extract was added to a spectro- photometer cuvette containing 745 ~L assay buf- fer at 25°C. Except where stated otherwise in the text, the assay buffer was 50 mM Bicine pH 8.0, WebRadiometers (c) ideally respond to radiant energy of all wavelengths (energy is greater per photon at shorter wavelengths; Eq. 4.2) and typically are calibrated in W m −2 (J m −2 s … hierarchy power bi
