Wavelength Range. Visible Often abbreviated to Vis. A visible spectrophotometer or colorimeter typically measures in the visible region of the electromagnetic spectrum (340 - 750 nm), although Biochrom spectrophotometers can measure up to 1100 nm (the near infrared region).. Spectrophotometry is widely used for quantitative analysis in various areas (e.g., chemistry, physics, biology, biochemistry, material and chemical engineering, clinical applications, industrial applications, etc). Any application that deals with chemical substances or materials can use this technique. In biochemistry, for example, it is used to determine enzyme-catalyzed reactions. In).

UV-Visible/NIR Spectrophotometer UH4150 Hitachi High. The instrument used in ultraviolet–visible spectroscopy is called a UV/Vis spectrophotometer. It measures the intensity of light passing through a sample (), and compares it to the intensity of light before it passes through the sample (). The ratio / is called the transmittance, and is usually expressed as a percentage (%T).. instrumentation in the mid 1930s and early 1940s. He founded Cary instruments just after leaving his position as vice-president in charge of development with Beckman Instruments, where he had been for 11 years. In April 1947 Applied Physics Corporation delivered the first commercial recording UV-Vis spectrophotometer, a Cary 11, to Mellon Institute in Pittsburgh, USA. At that time Applied.

Introduction to Spectrophotometery Protocol. The instrument used in ultraviolet–visible spectroscopy is called a UV/Vis spectrophotometer. It measures the intensity of light passing through a sample (), and compares it to the intensity of light before it passes through the sample (). The ratio / is called the transmittance, and is usually expressed as a percentage (%T).. The review covers the brief overview of basic principle and instrumentation of Raman spectroscopy along with selected and recent applications for characterization of drugs of abuse using this technique. These applications show the potential value of Raman spectroscopy in the qualitative and quantitative analysis of trace amounts of drugs of abuse and other illicit substances on different.
