Fluorimetric Techniques
Fluorimetric techniques provide specific and rapid analytical solutions which is a great boon to medical diagnosis as future course of action often depends on availability of reliable and accurate results in the shortest possible time.
Fluorescence techniques for environmental monitoring
Fluorescence spectroscopy provides a fast and precise means of monitoring of environmental pollutants in atmosphere and water.
Absorbance and Luminiscence spectroscopic measurements
The basic Absorbance and Luminiscence spectroscopic measurements system components are same for both the techniques.
A Review of Factors Contributing to Fluorescence Quenching
Analysis based on fluorescence characteristics of materials by fluroimetric analysis is a highly sensitive technique. At lower concentrations (ng levels or lower) the technique shows higher sensitivity in comparison to UV – Vis spectroscopy.
How are Fluorescence,Phosphorescence,Bioluminiscence and Chemiluminiscence different from each other?
Theoretically speaking all the terms mean the same and describe emission of light by substances not involving high temperatures.
Fluorescence of Molecules
Several compounds show fluorescence characteristics due to their molecular structural features.
What features contribute to fluorescence of molecules?
Fluorescence in natural species must have left you bewildered in earlier days. Bioluminescence refers to luminiscence arising from some living organisms or from some compounds extracted from such organisms.
What Factors contribute to Spectroscopic Techniques?
A wealth of information is provided by spectroscopic techniques as the expanse of electromagnetic spectrum is immensely vast and it offers a multitude of different wavelengths for such interactions to the chemical spectroscopist.
Validation of UV-Visible Spectrophotometer | Lab Training
A UV – Visible spectrophotometer can be seen in almost any laboratory be it a college lab, research lab or an industrial laboratory.
Benefits of Photodiode Array Detection over conventional Scanning detection
A Photodiode Array Detector is a microprocessor controlled multi-channel detector that permits simultaneous access to spectral data for several wavelengths simultaneously.
Chemical mapping of surfaces by FT-IR microscopy
FT-IR microscopy proved to be a very versatile tool for compositional characterization of materials.
Electromagnetic Spectrum
Electromagnetic radiation is radiant energy that is transmitted through space at the speed of light. Humans can experience it in the form of light and heat over a very small fraction of the almost infinite range of its wavelength range.
Beer–Lambert’s Absorbance law
Beer–Lambert’s Absorbance law is a universally accepted relationship which helps calculation of concentration of an absorbing species from measured absorbance values.
Scope of Applications of Raman Spectroscopy
Raman spectroscopy continues to expand its range of applications to diverse areas. In this article, scope of applications in other areas are briefly explored.
Approaches for the Enhancement of Raman Spectral Lines in Raman Spectroscopy
The present article explores some of the approaches adopted to enhance Raman spectral lines in Raman Spectroscopy.
What are the basics of Raman Spectroscopic transitions?
In Raman spectroscopy such scattered light is of no significance. It is only the 0.001% of incident light undergoing inelastic collisions that results in Stokes and anti-Stokes lines that are Raman active.
What Are the Differences between Raman and IR Spectroscopy?
Raman and IR spectroscopy are complementary techniques used for fingerprinting of molecules. Find out the difference between Raman and IR Spectroscopy in the article.
Raman Spectroscopy – A Powerful Tool for the Pharmaceutical Analyst
Raman spectroscopy offers several distinct benefits and can be used to study all types of samples ranging from solids, liquids, powders, gels, & slurries.
Photoacoustic Spectroscopy
Photoacoustic spectroscopy makes your analysis a lot simpler than other conventional spectroscopic techniques and offers potential saving of your valuable laboratory time.
UV-VIS Spectrophotometric detectors
A detector converts light into a proportional electrical signal which in turn provides the response of the spectrophotometer.
Universal Spectroscopic Solvent
Though it finds use in either pure form or in combination with acids, bases or specific reagents in spectroscopic studies it cannot be termed as a universal spectroscopic solvent as it shows absorption bands in NIR region.
How are Colorimeter, Photometer, Spectrometer and Spectrophotometer different from each other?
As its name suggests a spectrophotometer is a combination of a spectrometer and a photometer as its name suggests. It makes use of a sophisticated wavelength isolation device called a monochromator.
Useful tips to ensure top performance of your UV – VIS Spectrophotometer
Your UV-VIS Spectrophotometer is a highly sophisticated optical device designed to give accurate and reproducible data over a long period of time.
