Quantitation fluorescence

X-ray fluorescence—Quantitative analysis for elements in a wide variety of materials. 

When the absorptivity for a protein is known, the A28o and 4205 measurements require <30 min depending on the number of samples. When standards are used for quantitation with these assays or for intrinsic fluorescence quantitation, 1 hr is required.

Direct (in situ) fluorescence quantitation of the spots is not feasible. Durko et al. [174] recommend the extraction of the chromatoraphically separated Dis derivatives with acetone, evaporation of the extract and addition of 5 ml of sodium ethylate solution 25 min before fluorescence measurement. For the pyridoxamine derivative, excitation was 410 nm and the emission was measured at 480 nm.

Principles and Characteristics Fluorescence spectroscopy can also be used for quantitation as it provides greater selectivity and sensitivity than UV spectrophotometry. Fluorescence quantitation can be described by eq. (6.6) ... 

The Ba -h O2 reaction gives approximately symmetric forward-backward reactive scattering for Et = 2.2 kcal mole" and must proceed via a long-lived complex (also see references mentioned in ref. 28b). Rough vibrational and rotational BaO distributions were obtained by laser fluorescence. Quantitative assignments of populations were thwarted by formation of high J levels, rotational perturbations in the upper state, and lack of detailed...
