Use of the 0.22 /um Millipore Membrane for Light-Transmission Measurements of Acquatic Particles.
The use of the 0.22 um MILLIPORE cellulose membrane for the measurement of the in-vivo absorption of acquatic particles by the light-transmission method has been explored relative to the performance of the currently used 0.7 um WHATMAN GF/F glass-fiber filter. The standard solvent extraction process for pigment removal has been replaced by a newly developed process based on NaClO bleaching. The tests carried out indicate that the two filters exhibit comparable performances. It has been shown that a double measurement, performed first on the particles retained in the GF/F filter and then on the sample obtained passing the GF/F filtrate through a MILLIPORE membrane, allows for the selective determination of the absorption of the particle fraction with diameter in the 0.22-0.7 um range.
