Before gas-liquid chromatographic (GLC) analysis of the purine and pyrimidine bases, nucleosides, or nucleotides can be accomplished, these compounds must be converted to suitable volatile derivatives. The trimethylsilylation of active hydrogens is overwhelmingly preferred for GLC with nucleic acid
Positron annihilation lifetime spectra have been measured on styrenemethyl methacrylate, styrene-acrylonitrile, and styrene-butyl methacrylate copolymers. The results show that the longest lifetime 3 remains constant during extended PALS measurement in all experiment copolymers, and relative intensi
