Primary and secondary amines react reproducibly with fluorescamine to form pyrrolinones or aminoenone type chromophores with long wavelength absorption maxima in the 375410 and 310320 nm regions, respectively. A simple procedure has been worked out for the simultaneous colorimetric determination of primary...
