Laser-induced fluorescence detector for liquid chromatography: applications to protein analysis.
A laser-induced fluorescence detector for liquid chromatography was developed. This detector was assessed by utilizing it in conjunction with gel filtration chromatography. Using the 488 nm line of an argon ion laser for excitation and monitoring the emitted fluorescence centering at 535 nm, the limit of detection of fluorescein was 580 fM. Bovine serum albumin labeled with fluorescein was detected at a concentration of 500 fM.
