  2. Metallurgical assay - Wikipedia

    en.wikipedia.org/wiki/Metallurgical_assay

    A 19th-century assay laboratory in Tombstone Courthouse State Historic Park, Arizona. A model of a late 19th-century Canadian ( Yukon ) seal used to certify the quality of assayed gold . A metallurgical assay is a compositional analysis of an ore , metal , or alloy , usually performed in order to test for purity or quality.

  3. Loop-mediated isothermal amplification - Wikipedia

    en.wikipedia.org/wiki/Loop-mediated_isothermal...

    Loop-mediated isothermal amplification (LAMP) primers [1] Loop-mediated isothermal amplification (LAMP) product [1]. In LAMP, the target sequence is amplified at a constant temperature of 60–65 °C (140–149 °F) using either two or three sets of primers and a polymerase like Bst Klenow fragment with high strand displacement activity in addition to a replication activity.

  4. Assay - Wikipedia

    en.wikipedia.org/wiki/Assay

    A high throughput assay can be either an endpoint or a kinetic assay usually done on an automated platform in 96-, 384- or 1536-well microplate formats (High Throughput Screening). Such assays are able to test large number of compounds or analytes or make functional biological readouts in response to a stimuli and/or compounds being tested. [6]

  5. Grignard reagent - Wikipedia

    en.wikipedia.org/wiki/Grignard_reagent

    Specially activated magnesium, such as Rieke magnesium, circumvents this problem. [5] The oxide layer can also be broken up using ultrasound, using a stirring rod to scratch the oxidized layer off, [6] or by adding a few drops of iodine or 1,2-Diiodoethane. Another option is to use sublimed magnesium or magnesium anthracene. [7]

  6. Blood test - Wikipedia

    en.wikipedia.org/wiki/Blood_test

    A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test , are often grouped together into one test panel called a blood panel or blood work .

  7. Loss on ignition - Wikipedia

    en.wikipedia.org/wiki/Loss_on_ignition

    Loss on ignition (LOI) is a test used in inorganic analytical chemistry and soil science, particularly in the analysis of minerals and the chemical makeup of soil. It consists of strongly heating ( "igniting" ) a sample of the material at a specified temperature, allowing volatile substances to escape, until its mass ceases to change.

  8. Flame test - Wikipedia

    en.wikipedia.org/wiki/Flame_test

    A flame test involves introducing a sample of the element or compound to a hot, non-luminous flame and observing the color of the flame that results. [4] The compound can be made into a paste with concentrated hydrochloric acid, as metal halides , being volatile, give better results. [ 5 ]

  9. Titration - Wikipedia

    en.wikipedia.org/wiki/Titration

    An assay is a type of biological titration used to determine the concentration of a virus or bacterium. Serial dilutions are performed on a sample in a fixed ratio (such as 1:1, 1:2, 1:4, 1:8, etc.) until the last dilution does not give a positive test for the presence of the virus.
