As pointed out by van Es and Bont (1, 2) absorption optics with an electronic scanning system used in connection with the analytical ultracentrifuge have certain advantages for the determination of molecular weights. These authors have already carried out measurements at exactly the meniscus and exa

The mechanism by which sulfonated 2-hydroxybenzophenone ultraviolet (UV) absorbers protect wool fabric against photoyellowing has been studied. The absorption and luminescence properties of two 2-hydroxybenwphenone-5-sulfonates and four 2-hydroxybenzophenone-2'sulfonates are compared. The 2-hydroxy-

A sample solution (1 ml) of D-ghCOSe, a 1% aqueous solution ( 1 ml) of 2-cyanoacetamide, and 0.1 M borate buffer (pH 9.0, 2 ml) are mixed and heated for 10 min in a boiling-water bath. Measurement of the absorbance of the reaction mixture at 276 nm allows the rapid and simple determination of 5 to 7
