What is the name of the point at which wavelength independent pH and absorbance?
isosbestic point
When Isosbestic point observed?
If the spectra of two compounds with a constant total concentration cross at any wavelength, all mixtures with the same total concentration will go through that same point. The appearance of isobestic points in a chemical reaction is good evidence that we are observing one main species being converted to one other major species.
Who uses atomic absorption spectroscopy?
Atomic absorption spectrophotometry is a method in analytical chemistry.
How do you analyze thorium?
1. Emission optical spectrography 2. ICP mass spectrometry 3. Atomic absorption spectrophotometry 4. Gravimetry 5. Volumetry/Potentiometry 6. ICP atomic spectrometry 7. Spectrophotometry with arsenazo III etc.
Difference between spectrophotometry and differential spectrophotometry?
Differential spectrophotometry is a spectrophotometric analytical technique in which a solution of the sample's major component is placed in the reference cell and the recorded spectrum represents the difference between the sample cell and the reference cell...basically it uses major component of system as reference and NOT solvent ..for example if a enzyme ligand system is to be assayed ..enzyme + solvent is reference and enzyme + ligand + solvent is test sample..its for quantitative detection.
What is the name of the point at which wavelength independent pH and absorbance?
isosbestic point
What does it mean if there is no isosbestic point on an asborbance spectra?
Nothing! -- Not at all!The Absence of an Isosbestic Point on a couple of Spectra on the same Plot doesn't mean anything at all!Without any other very relevant Information absolutely no Statement of any kind is possible!
What are types of spectrophotometry?

What is difference between photospectrometry and spectrophotometry?
There is no such thing as photospectrometry. It's sometimes used when actually meaning spectrophotometry. This usage is incorrect.
What is atomic spectrophotometry?
spectrophotometry is a branch of spectroscopy dealing with measurement of radiant energy transmitted or reflected by a body as function of wave lenght %
How do you determine heavy metal in water?
By chemical analysis: Uv-vis absorption spectrophotometry, atomic absorption spectrophotometry, inductively coupled plasma mass spectrometry, inductively coupled plasma emmission spectrometry, polarograhy, phosphorescence fluorometry, flame spectrophotometry, etc.
What is the definition of Spectrophotometry?
The term "Spectrophotometry" refers to an instrument that is often used to determine the intensity of the various wavelengths in a spectrum of light. This tool is a part of analytical chemistry.
When Isosbestic point observed?
If the spectra of two compounds with a constant total concentration cross at any wavelength, all mixtures with the same total concentration will go through that same point. The appearance of isobestic points in a chemical reaction is good evidence that we are observing one main species being converted to one other major species.
What dyes spectroscopic study?
Spectrophotometry can be applied to the study of a large number of substances.
What is the importance of automobile?
To take a person or groups of people from Point A to Point B.
Spectrophotometric methods using light?
For example UV-VIS absorption spectrophotometry.
How do you determine if the nitrate content of groundwater is over epa limits?
by the use of optical spectrophotometry.
