    A list of chemical analysis methods with acronyms. A. Atomic absorption spectroscopy (AAS) Atomic ... Analytical chemistry; List of materials analysis methods

  3. Analytical chemistry - Wikipedia

    en.wikipedia.org/wiki/Analytical_chemistry

    Analytical chemistry studies and uses instruments and methods to separate, identify, and quantify matter. [1] In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes.

  4. Quantitative analysis (chemistry) - Wikipedia

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

    The general expression Qualitative Analysis [...] refers to analyses in which substances are identified or classified on the basis of their chemical or physical properties, such as chemical reactivity, solubility, molecular weight, melting point, radioactivity properties (emission, absorption), mass spectra, nuclear half-life, etc. Quantitative Analysis refers to analyses in which the amount ...

  5. Gravimetric analysis - Wikipedia

    en.wikipedia.org/wiki/Gravimetric_analysis

    Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the relative ...

  6. Elemental analysis - Wikipedia

    en.wikipedia.org/wiki/Elemental_analysis

    Elemental analysis is a process where a sample of some material (e.g., soil, waste or drinking water, bodily fluids, minerals, chemical compounds) is analyzed for its elemental and sometimes isotopic composition.

  7. Sample preparation - Wikipedia

    en.wikipedia.org/wiki/Sample_preparation

    In analytical chemistry, sample preparation (working-up) refers to the ways in which a sample is treated prior to its analyses. Preparation is a very important step in most analytical techniques, because the techniques are often not responsive to the analyte in its in-situ form, or the results are distorted by interfering species.

  8. Analysis of water chemistry - Wikipedia

    en.wikipedia.org/wiki/Analysis_of_water_chemistry

    Water chemistry analysis is often the groundwork of studies of water quality, pollution, hydrology and geothermal waters. Analytical methods routinely used can detect and measure all the natural elements and their inorganic compounds and a very wide range of organic chemical species using methods such as gas chromatography and mass spectrometry .

  9. Chemical reaction - Wikipedia

    en.wikipedia.org/wiki/Chemical_reaction

    Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes can occur. The substance (or substances) initially involved in a chemical reaction are called reactants or reagents.
