  2. Analytical chemistry - Wikipedia

    en.wikipedia.org/wiki/Analytical_chemistry

    Analytical chemistry has been important since the early days of chemistry, providing methods for determining which elements and chemicals are present in the object in question. During this period, significant contributions to analytical chemistry included the development of systematic elemental analysis by Justus von Liebig and systematized ...

  3. Standard solution - Wikipedia

    en.wikipedia.org/wiki/Standard_solution

    In analytical chemistry, a standard solution (titrant or titrator) is a solution containing an accurately known concentration.Standard solutions are generally prepared by dissolving a solute of known mass into a solvent to a precise volume, or by diluting a solution of known concentration with more solvent. [1]

  4. Electroanalytical methods - Wikipedia

    en.wikipedia.org/wiki/Electroanalytical_methods

    Potentiometry passively measures the potential of a solution between two electrodes, affecting the solution very little in the process. One electrode is called the reference electrode and has a constant potential, while the other one is an indicator electrode whose potential changes with the sample's composition.

  5. Calibration curve - Wikipedia

    en.wikipedia.org/wiki/Calibration_curve

    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. [1]

  6. Atomic absorption spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Atomic_absorption_spectroscopy

    In analytical chemistry the technique is used for determining the concentration of a particular element (the analyte) in a sample to be analyzed. AAS can be used to determine over 70 different elements in solution, or directly in solid samples via electrothermal vaporization, [ 1 ] and is used in pharmacology , biophysics , archaeology and ...

  7. List of important publications in chemistry - Wikipedia

    en.wikipedia.org/wiki/List_of_important...

    Traité Élémentaire de Chimie, 1789, available in English as Elementary Treatise of Chemistry; Description: This book was intended as an introduction to new theories in chemistry and as such, was one of the first Chemistry textbooks. [9] Importance: Introduction, Influence.

  8. Quantitative analysis (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Quantitative_analysis...

    In analytical chemistry, quantitative analysis is the determination of the absolute or relative abundance (often expressed as a concentration) of one, several or all particular substance(s) present in a sample. [1] It relates to the determination of percentage of constituents in any given sample. [2]

  9. Spectral line shape - Wikipedia

    en.wikipedia.org/wiki/Spectral_line_shape

    This process is used in analytical chemistry to determine the composition of a mixture of the components of known molar absorptivity spectra. For example, if the heights of two lines are found to be h 1 and h 2, c 1 = h 1 / ε 1 and c 2 = h 2 / ε 2. [13] Parameters of the line shape are unknown.
