What type of electromagnetic radiation is absorbed by the sample in mass spectrometry?

Mass spectrometry doesn't use electromagnetic radiation, hence why it is not called Mass spectroscopy. Instead Mass spectrometry uses high energy electrons to ionize the sample molecules, which helps determine the mass of the molecules and any fragmented ions from the parent ion.

What is atomic absorption spectrophotometry and what are its application in food?
Well, let me try to improve this answer a little... Atomic spectroscopy is, primarily, the science that investigates the interaction of electromagnetic radiation (such as X-rays, ultra-violet and visible light) with atoms, usually by means of absorption or emission. These principles of interaction can be combined in an instrument called "spectrometer" that, finally, can be used to quantify several elements of the periodic table in all kinds of sample that you can imagine, from water to rocks. This is usually done by associating the amount of energy absorbed or emitted by an atom or atom cloud to the quantity of atoms in a given sample (or, indirectly, to the concentration of the element in that sample). The most usual techniques associated to atomic spectroscopy are atomic absorprtion spectrometry, optical (or atomic) emission spectrometry and X-ray fluorescence spectrometry. Hope that helps... Atomic Spectroscopy is the determination of elemental composition by its electromagnetic or mass spectrum. Sorry if this wasn't the exact answer you're looking for, but it was the only thing I could find. It took me FOREVER to find the answer to this question for a school project I was doing. I hope this is what you need!!! >Smile< :-)
In mass spectrometry why do you have to convert the solid sample into vapor state?
Because solid need to be ionized and thespectrometer can not ionize solid state so that why it converts to vapor state.
What is the difference between Chromatography and Spectrometry?
GCMS involves running the sample through a mass spectrometer following the data received from chromatography. MS fragments the analytes to show patterns specific to the analyte (and the ionization technique and sector powers) therefore allowing the analyte to be identified. GC is used to separate all volatile substituents of a sample so they can be identified one by one.
What is absorption spectroscopy?
The colors absorbed when an element gains energy
The color of light given off when a sample is heated corresponds to?
heated of the element heat absorbed by the sample amount of energy added to the sample energy difference between the ground state and exited states of an element.
What are the weaknesses of infrared spectrometry?
Infrared spectrometry cannot be used quantitatively. It also involves complex sample preparation. In addition, infrared spectrometry may be robust as its sample preparation may affect its results.
What advantages does mass spectrometry have over nuclear magnetic resonance spectrometry?
Mass spectrometry can analyze samples quicker, has a higher sensitivity, and can conduct analysis with smaller sample volumes.

Why is it advisable to keep atmospheric moisture from getting into the sample?
It is to prevent contamination since moisture from air could be absorbed by the sample.
Is it possible to acquire a sharp peak for the OH groups of alcohols and phenols in infrared spectrometry?
Yes. se a very dilute solution of the sample and gas phase.
Why is now mass spectroscopy used instead of radiocarbon dating?
Mass spectrometry has not replaced radiocarbon dating, it is used as a better way to measure the amount of carbon-14 in the sample that permits smaller sample sizes and improved accuracy.
What is an Example of where energy transfer by radiation is occurring?
Some examples of energy transfer by radiation are: 1) standing in sunlight and feeling the heat on your face (UV radiation is entering the skin, converting to infrared radiation, and is absorbed by your tissues); 2) sitting near a fire and feeling the heat on your skin (infrared radiation transfer); 3) chemical reactions that occur due to a source of radioactivity (gamma radiation, being high-energy photons, travel from the radioactive source through the air into the target sample, and induce chemical reactions
What is color absorption?
Absorption spectroscopy refers to spectroscopic techniques that measure the absorption of radiation, as a function of frequency or wavelength, due to its interaction with a sample. The sample absorbs energy, i.e., photons, from the radiating field. The intensity of the absorption varies as a function of frequency, and this variation is the absorption spectrum. Absorption spectroscopy is performed across the electromagnetic spectrum.
In mass spectrometry why do you have to convert the solid sample into vapor state?
Because solid need to be ionized and thespectrometer can not ionize solid state so that why it converts to vapor state.
To calculate the amount of heat absorbed as a substance melts what information is not needed?
the density of the sample.
A sample constructed to represent the major characteristics of the universe?
One possible sample constructed to represent the major characteristics of the universe is the cosmic microwave background radiation. This radiation is a remnant of the Big Bang and provides clues about the early universe's temperature and density. By studying this radiation, scientists can gain insights into the universe's origins, evolution, and composition.
How do you test for nickel in meteorites?
A quick test to determine what is in a sample of a meteorite (or anything else, for that matter) is to run that sample through a mass spectrometer. Mass spectrometry (MS) will tell you whether nickel is among the constituent elements in that sample you just put through the machine. Use the links below to learn more.
