  2. Certified reference materials - Wikipedia

    en.wikipedia.org/wiki/Certified_reference_materials

    A certified reference material is a particular form of measurement standard. Reference materials are particularly important for analytical chemistry and clinical analysis. [2] Since most analytical instrumentation is comparative, it requires a sample of known composition (reference material) for accurate calibration.

  3. LCR meter - Wikipedia

    en.wikipedia.org/wiki/LCR_meter

    An LCR meter is a type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component. [1] In the simpler versions of this instrument the impedance was measured internally and converted for display to the corresponding capacitance or inductance value.

  4. Laboratory quality control - Wikipedia

    en.wikipedia.org/wiki/Laboratory_quality_control

    Laboratory quality control is designed to detect, reduce, and correct deficiencies in a laboratory's internal analytical process prior to the release of patient results, in order to improve the quality of the results reported by the laboratory.

  5. Characterization (materials science) - Wikipedia

    en.wikipedia.org/wiki/Characterization...

    Characterization, when used in materials science, refers to the broad and general process by which a material's structure and properties are probed and measured. It is a fundamental process in the field of materials science, without which no scientific understanding of engineering materials could be ascertained.

  6. Quantitative analysis (chemistry) - Wikipedia

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

    Once the presence of certain substances in a sample is known, the study of their absolute or relative abundance could help in determining specific properties. Knowing the composition of a sample is very important, and several ways have been developed to make it possible, like gravimetric [3] and volumetric analysis. Gravimetric analysis yields ...

  7. List of materials properties - Wikipedia

    en.wikipedia.org/wiki/List_of_materials_properties

    A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.

  8. Good laboratory practice - Wikipedia

    en.wikipedia.org/wiki/Good_Laboratory_Practice

    The Agency utilizes data obtained from laboratory inspections and audits to oversee the use of pesticides and industrial chemicals. [33] 40 CFR Part 160, Good Laboratory Practice Standards pertains specifically to the Good Laboratory Practice (GLP) standards for pesticide chemicals. It establishes the requirements for conducting studies and ...

  9. Safety data sheet - Wikipedia

    en.wikipedia.org/wiki/Safety_data_sheet

    An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
