Instrumental analysis is a field of analytical chemistry that investigates analytes using scientific instruments. Block diagram of an analytical instrument showing ...
The first instrumental analysis was flame emissive spectrometry developed by Robert Bunsen and Gustav Kirchhoff who discovered rubidium (Rb) and caesium (Cs) in 1860. [4] Most of the major developments in analytical chemistry took place after 1900. During this period, instrumental analysis became progressively dominant in the field.
The journal publishes the complete scientific documentation of the CERN Large Hadron Collider machine and detectors.These papers are published as open access. [6] It also publishes the technical reports concerning the Planck Low Frequency Instrument on board the European Space Agency's Planck satellite, which was launched in May 2009, and the three-volume technical report of the Deep ...
A calibration curve plot showing limit of detection (LOD), limit of quantification (LOQ), dynamic range, and limit of linearity (LOL).. In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.

In NMR spectroscopy, e.g. of the nuclei 1 H, 13 C and 29 Si, frequencies depend on the magnetic field, which is not the same across all experiments. Therefore, frequencies are reported as relative differences to tetramethylsilane (TMS), an internal standard that George Tiers proposed in 1958 and that the International Union of Pure and Applied Chemistry has since endorsed.
In linear analysis, there is no test to falsify the assumption the is instrumental relative to the pair (,). This is not the case when X {\displaystyle X} is discrete. Pearl (2000) has shown that, for all f {\displaystyle f} and g {\displaystyle g} , the following constraint, called "Instrumental Inequality" must hold whenever Z {\displaystyle ...
Position-specific isotope analysis, also called site-specific isotope analysis, is a branch of isotope analysis aimed at determining the isotopic composition of a particular atom position in a molecule. Isotopes are elemental variants with different numbers of neutrons in their nuclei, thereby having different atomic masses. Isotopes are found ...
