The functioning of this instrument is relatively straightforward. A beam of light from a visible and/or UV light source (colored red) is separated into its component wavelengths by a prism or diffraction grating. Each monochromatic (single wavelength) beam in

Sodium Dodecyl Sulphate And Triton X-100 Have On Protein Concentration. INTRODUCTION Spectroscopy is used as a collective term for all the analytical techniques based on the interaction of light and matter. Spectrophotometry is one of the branches of spectroscopy where we measure the absorption of light by molecules that are in a gas or vapour state or dissolved molecules/ions (Tombs‚ et.al‚ 1959). Spectroscopy is the use of electromagnetic radiation by a sample in order to identify components of

atoms and molecules are determined. This technique is spectroscopy where it absorbs‚ emits‚ or scatters electromagnetic radiation. Electromagnetic radiation has particle-like properties having photons and quantum and wave-like properties with frequency and wavelength. To make molecules visible through light‚ the wavelength of the molecule should be longer than the wavelength of the light. One spectroscopic

Abstract Pigments extracted from different greens have different polarities and may be different colors. Mixed pigments can be separated using chromatography paper. Chromatography paper is able to separate mixed pigments due to their polarity and solubility. Pigments of chlorophyll a‚ chlorophyll b and beta carotene will be separated on chromatography paper because each has its own polarity and solubility‚ which results in different distance traveled up the paper. Beta carotene is non-polar so it

INTRODUCTION: In atomic spectroscopy the samples are vaporized at 2000-8000k. The process of this involves two steps ‚ one is atomization of sample and the other is absorption of light radiation from light source. The atoms in the vapour are measured by absorption or emission at characteristic wave lengths. The main usage of this was to detect one element from another in the complex sample which has taken ie.‚ it has ability to perform multiple element analyses. Absorbance should obey Beer’s law

Trace Evidence Trace evidence is an important part of a team in solving crimes in forensic investigations. According to Edmond Locard‚ there is specific that no matter wherever people interact with their environment or is physically involved in a crime often leaves something at or something away from the scene. Those in this category of evidence include many diverse types of macroscopic or microscopic materials that certain examples are easily visible to our “naked eye”. The subject is broad and
