It is a well-known fact that ordinary white light comprises of a mix of different wavelengths or colours. We are all familiar with the different colours of the rainbow which are in fact different colours comprising white light. White light is seldom used as such in spectroscopic analysis though of visible light source is a
Ideally the absorbance spectrum of a solution containing a single analyte should be a single absorption band at the wavelength of maximum absorbance. However, in real samples the spectrum gets influenced by presence of other interfering species. Such interferences can be easily eliminated by adopting different approaches covered in the article. Interferences in UV- Visible
Colorimetry and spectrophotometry vary in that colorimetry utilizes fixed wavelengths that are only observable in the visible spectrum, but spectrophotometry can use wavelengths from a larger range. We can utilize spectrophotometry and colorimetry to identify compounds based on their absorption and emission characteristics. Furthermore, this is a simple method for determining the concentration of a
Optical spectroscopic methods of analysis are based upon the interaction of electromagnetic radiation with matter. The objective of writing this article is to brief you on the fundamental concepts of commonly used spectroscopic techniques Electromagnetic Spectrum The electromagnetic spectrum provides the spectroscopist a wealth of information. Each region of the electromagnetic spectrum is characterised by
Hi everyone, we are here with some important information that will save you tons of headaches. I have two words: cuvette rack. Get yourself one now! So it’s only fair if I explain why I feel that you need a cuvette rack so strongly. I’ve made a list of the top 10 reasons why you
Cuvette volume is the maximum amount of sample that a cuvette can safely hold. The most common capacity is 3.5 mL for a standard 10 mm cell, but how do we figure it out? How We Calculate Cuvette Volume It is very easy to calculate the volume of any cuvette. We have dimension charts on

Many laboratories are subject to regulatory requirements that e.g. are prescribed by Quality Management Systems. These laboratories are thus obligated to test work equipment and analysis instruments, including (spectro-) photometers, on a regular basis. What if such regulations do not apply to your lab? In this case, testing is not absolutely necessary, as it is

For the purpose of photometric analyses of liquid samples, the solution must be placed into the light path of a photometer in a defined format. Cuvettes, i.e. sample containers featuring optical windows, are the standard choice for this application.
