Lecture on Atomic Mass Spectrometry (Chapter 2) part 1

A set of vocabulary flashcards covering key concepts and terms related to Atomic Mass Spectrometry as discussed in the lecture.

Atomic Mass Spectrometry (AMS)

A technique used to identify elements and their concentrations in a sample based on the mass-to-charge ratio of ions.

Ionization

The process of converting gaseous atoms or molecules into ions, which can be either positively or negatively charged.

Desolvation

The removal of solvent molecules from analytes to obtain a dry sample for analysis.

Atomization

The process of converting a sample from a solid or liquid state into a gaseous state at high temperature.

Isotopic Atomic Ratio

The ratio of isotopes present in a sample, which can be measured using atomic mass spectrometry.

Vacuum

An environment created in mass spectrometry to prevent interaction between analyte ions and residual gas.

Mass-to-Charge Ratio (m/z)

A key parameter in mass spectrometry that represents the mass of an ion divided by its charge.

Transducer

A device in mass spectrometry that converts the current produced by ions into a measurable electronic signal.

Combustion Zone

A region within the mass spectrometer where the sample is combusted for ionization.

Calibration

The process of adjusting the mass spectrometer's measurements to ensure accuracy.

Avoagadro's Number

6.022 imes 10^{23}, the number of atoms or molecules in one mole of a substance.

Dalton (Da)

A unit of mass used to express atomic and molecular weights, defined as 1/12 the mass of a carbon-12 atom.

Signal Processor

The component in mass spectrometry that converts ion currents into data outputs for analysis.

Nebulization

The process of converting liquid samples into a mist of fine droplets for analysis in mass spectrometry.

Quantification

The process of measuring the amount of a substance in a sample, often achieved through mass spectrometry.
