Calibration Curve
A plot of instrument response against known analyte concentration, used to determine unknowns.
Analytical Chemistry & SpectroscopyCarbon-13 NMR
An NMR technique that detects the carbon-13 nucleus to reveal the carbon skeleton of a molecule.
Analytical Chemistry & SpectroscopyChemical Shift
The position of an NMR signal relative to a reference, expressed in parts per million of the operating frequency.
Analytical Chemistry & SpectroscopyChromatography
A family of separation techniques that partition components between a stationary and a mobile phase.
Analytical Chemistry & SpectroscopyChromophore
The part of a molecule responsible for absorbing light at a particular wavelength.
Analytical Chemistry & SpectroscopyColumn Chromatography
A preparative technique in which a mixture is separated by passing it down a vertical column packed with stationary phase.
Analytical Chemistry & SpectroscopyComplexometric Titration
A titration based on the formation of a stable complex between the analyte metal ion and a chelating titrant.
Analytical Chemistry & SpectroscopyConfidence Interval
The range within which the true value of a measured quantity is expected to lie with a stated probability.
