What is the difference between flame photometer and atomic absorption spectrometer?
A spectrometer is a general term for an optical instrument. Spectrometric methods convey a large group of analytical methods based on molecular or atomic spectroscopy. Spectroscopic instruments will typically contain a stable source of radiant energy, a transparent veil for the sample or blank, a component to separate different wavelengths of light, a detector, and a readout/processor.
Photometers are simpler in design compared to spectrophotometers. They are less expensive, more convenient, easier to maintain, and good for field work. Some photometers include: visible photometers, probe-type photometers, and general purpose photometers using adjustable filters.
Spectrophotometers may have a few more mirrors, slits, a grating, and maybe a filter to top if off. Some examples include the popular Spectronic 20, Varian Cary 100, or even miniature fiber-optic spectrometers.

What is the difference between a colorimeter and flame photometer?
A colorimeter is a scientific instrument that measures the intensity of light passing through a pure sample. In biology, colorimeters are used to monitor the growth of cultures. As the culture grows, the growing medium becomes more cloudy and absorbs more light.
What is the difference between an electroscope and a spectroscope?
A spectrophotometer consists of two instruments, namely a spectrometer for producing light of any selected color (wavelength), and a photometer for measuring the intensity of light. For solutions where intensity of light is proportional to the concentration, we use spectrophotometer.
Is there any relationship between sound frequency and sound absorption?
Yes - the amount of absorption can depend on the frequency.
One difference between algae and plants is that?
Algae lack specialized tissues like roots, stems, and leaves that are present in plants. Instead, algae have simple structures for attachment and nutrient absorption.
What is resonance line of atomic absorption spectroscopy?
Atomic absorption spectrometry is the measurement of the absorption of optical radiation by atoms in the gaseous state. Usually only absorptions involving the ground state, known as resonance lines, are observed.
What is the difference between photometer and spectrometer?
The difference between the photometer and the spectrometer is a matter of complexity. Both are used to measure color absorbency quantitatively, but photometers are much simpler in design, having fewer parts, and as such are less expensive and easier to obtain. They're usually not quite as detailed in results as a spectrometer, however.
What is the difference between a spectrometer and a spectrophotometer?
A spectrometer measures the intensity of light at different wavelengths, while a spectrophotometer measures the amount of light absorbed or transmitted by a sample at specific wavelengths.
What are the differences between a photo spectrometer and a spectrophotometer, and how do these differences impact their respective applications in analytical chemistry?
A photometer measures the intensity of light, while a spectrophotometer measures the intensity of light at different wavelengths. This allows a spectrophotometer to provide more detailed information about the composition of a sample. In analytical chemistry, a spectrophotometer is often preferred for its ability to analyze complex mixtures and identify specific compounds based on their unique light absorption patterns.

What is the difference between Aston's mass spectrograph and Dempster's mass spectrometer?
Aston's mass spectrograph is a magnetic sector mass spectrometer that separates ions based on their mass-to-charge ratio using magnetic and electric fields. Dempster's mass spectrometer is an early design of a mass spectrometer that used electric and magnetic fields to separate ions based on their mass-to-charge ratio. Aston's design was an improvement over Dempster's, offering higher resolution and precision in analyzing isotopic composition.
What are the differences between a spectrometer and a spectrophotometer, and how do these differences impact their respective applications in analytical chemistry?
A spectrometer measures the intensity of light at different wavelengths, while a spectrophotometer measures the amount of light absorbed or transmitted by a sample at specific wavelengths. The main difference is in the type of data they provide - spectrometers give information on the intensity of light, while spectrophotometers give information on the absorption or transmission of light by a sample. This impacts their applications in analytical chemistry as spectrometers are used for qualitative analysis, such as identifying substances based on their unique light absorption patterns, while spectrophotometers are used for quantitative analysis, such as measuring the concentration of a substance in a sample based on its light absorption.
What is the difference between absorption costing and active base costing?
there is have some differeance . 1.
What are the differences between a colorimeter and a spectrometer in terms of their functionality and applications?
A colorimeter measures the intensity of a specific color in a sample, while a spectrometer measures the entire spectrum of light. Colorimeters are used for simple color analysis, while spectrometers are used for more detailed analysis of substances based on their light absorption or emission properties.
Difference between absorption costing AND target costing?
Target costing is when you have a goal for the project and its costs. Absorption costing is when you need to fix the excess spending.
What is the difference between a colorimeter and flame photometer?
A colorimeter is a scientific instrument that measures the intensity of light passing through a pure sample. In biology, colorimeters are used to monitor the growth of cultures. As the culture grows, the growing medium becomes more cloudy and absorbs more light.
What is the difference between assimilation and absorption?
Absorption is where nutrients are moved from the lumen in to the bloodstream or the lymph. here they are transported to tissues where they are assimilated :used for energy, growth etc
What is the difference between spectrophotometer and fluorimeter?
A spectrometer shoots light through a sample and detects absorbance while a fluorimeter detects the intensity of fluorescence of a given sample.
