The technique of UV / Visible Spectro-Photometry has long been used as a universal laboratory tool covering a wide range of ranging from clinical assays through chemical analysis to water quality monitoring. The technique has enjoyed a molecular biology and the need to quantify DNA and proteins; here, the simplicity of use, the non-destructive nature of the sampling and the cost effectiveness of the measurement has proved very beneficial in the modern laboratory, also, due to new controls on food Standards., Spectrophotometry is the cost effective solution to product quality monitoring in the smaller laboratories.
