Quantitative determination of diosgenin in Dioscorea zingiberensis cell cultures by microplate- spectrophotometry and high-performance liquid chromatography

, 2012
Quantitative determination of diosgenin was carried out by multi-well microplate-spectrophotometry and high-performance liquid chromatography (HPLC) in this study. Diosgenin detection by microplatespectrophotometry depended on the formed yellow substance

Atomic Absorption Spectrophotometry

Medicine, Science and the Law, 1973
Historically flame emission spectroscopy was developed first. Routine analysis showed the advantage of measuring absorption over emission for many metals. Instrumentation requirements are:— 1. Pressure regulators and flowmeters with the sources of gases; 2. Atomizer; 3. Burner; 4. Optical system; 5. Detector. In addition, an energy source, e.g.,

Spectrophotometry and Fluorometry

1981
Before going into detail, it may be advisable to provide an overview of the principles that underlie the techniques to be discussed in this chapter. The most important physical principles involve the relationships between the wave and particle properties of both light and matter and the interaction of light with matter.

Notes on Spectrophotometry

Mathematical Proceedings of the Cambridge Philosophical Society, 1927
The source of light used as a background is an important factor in determining the convenience and accuracy of ultra-violet absorption work, etc. If a source of light of constant intensity is available, a direct comparison method can be used and it is only necessary to calibrate the plates.
