  2. Hydrodemolition - Wikipedia

    en.wikipedia.org/wiki/Hydrodemolition

    Hydrodemolition (also known as hydro demolition, hydroblasting, hydro blasting, hydromilling, waterblasting, and waterjetting) is a concrete removal technique which utilizes high-pressure water, often containing an abrasive material, to remove deteriorated and sound concrete as well as asphalt and grout. This process provides an excellent ...

  3. Post-excavation analysis - Wikipedia

    en.wikipedia.org/wiki/Post-excavation_analysis

    The examination of surfaces give clues as to how tools were made. Typical design techniques include: fracturing, pecking or polishing. Sometimes, stone tools are continually modified and keen attention to surfaces is necessary to recognize each stage of the manufacture process. [16] An example of a lab station set up for electrolysis

  4. Two-dimensional gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Two-dimensional_gel...

    The two dimensions that proteins are separated into using this technique can be isoelectric point, protein complex mass in the native state, or protein mass. [citation needed] The separation by isoelectric point is called isoelectric focusing. Thereby, a pH gradient is applied to a gel and an electric potential is applied across the gel, making ...

  5. 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.

  6. Elemental analysis - Wikipedia

    Modern simultaneous CHNS combustion analyzer. 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. Core sample - Wikipedia

    en.wikipedia.org/wiki/Core_sample

    Rock core samples, the product of a diamond rig.A pied butcherbird perches nearby.. A core sample is a cylindrical section of (usually) a naturally-occurring substance. Most core samples are obtained by drilling with special drills into the substance, such as sediment or rock, with a hollow steel tube, called a core drill.

  8. Gel permeation chromatography - Wikipedia

    en.wikipedia.org/wiki/Gel_permeation_chromatography

    The technique is often used for the analysis of polymers. As a technique, SEC was first developed in 1955 by Lathe and Ruthven. [ 2 ] The term gel permeation chromatography can be traced back to J.C. Moore of the Dow Chemical Company who investigated the technique in 1964. [ 3 ]
