## Abstract This work suggests an HPLC method for qualitative and quantitative determination of __N__^ε^(2‐amino‐2‐carboxyethyl)‐L‐lysine (LAL). LAL was released from total hydrolysates of various proteins of animal origin and derivatized with dansyl chloride. The performance of two different colum

A highly sensitive and specific assay method for cystamine using high-performance liquid chromatography has been developed. The method is based on postcolumn derivatization of cystamine with o-phtalaldehyde in the presence of 2-mercaptoethanol and sodium hypochlorite. The separation of cystamine was

Two series of segmented polyurethanes, one containing 50% soft segments and the other with 70% soft segments were synthesized. Chemical crosslinks were introduced through the hard segment in a controlled way. Chemical polyurethane networks were characterized by swelling. The effect of the degree of
