Simplified serum phosphorus analyses by continuous-flow ultraviolet spectrophotometry.
Clinical Chemistry, 1972 Serum phosphorus can be measured by continuous-flow uv spectrophotometry without reduction of the phosphomolybdate complex. The dilute sample is dialyzed into dilute (1 ml/100 ml) sulfuric acid, then mixed with an ammonium molybdate— sulfuric acid—"Tween

Applied ultraviolet spectrophotometry of fats and oils [PDF]
Oil & Soap, 1946 The chemist has in the spectrophotometric method a rapid and simple means of studying changes in the double bond systems of fatty acids. The method is highly sensitive. It has found application in studies of processing of oils, improvement of drying oils, catalytic hydrogenation, routine analytical work, soap and tallow control, as well as in nutrition
