  2. Detection limit - Wikipedia

    en.wikipedia.org/wiki/Detection_limit

    Most analytical instruments produce a signal even when a blank (matrix without analyte) is analyzed.This signal is referred to as the noise level. The instrument detection limit (IDL) is the analyte concentration that is required to produce a signal greater than three times the standard deviation of the noise level.

  3. Laboratory information management system - Wikipedia

    en.wikipedia.org/wiki/Laboratory_information...

    Lab orders in the LIMS module of the GNU Health project. A laboratory information management system (LIMS), sometimes referred to as a laboratory information system (LIS) or laboratory management system (LMS), is a software-based solution with features that support a modern laboratory's operations.

  4. Laboratory quality control - Wikipedia

    en.wikipedia.org/wiki/Laboratory_quality_control

    An example of a Levey–Jennings chart with upper and lower limits of one and two times the standard deviation. A Levey–Jennings chart is a graph that quality control data is plotted on to give a visual indication whether a laboratory test is working well.

  5. Lab notebook - Wikipedia

    en.wikipedia.org/wiki/Lab_notebook

    However following March 2013, lab notebooks are of limited legal use in the United States, due to a change in the law that grants patents to the first person to file, rather than the first person to invent. [7] The lab notebook is still useful for proving that work was not stolen, but can no longer be used to dispute the patent of an unrelated ...

  6. Field experiment - Wikipedia

    en.wikipedia.org/wiki/Field_experiment

    There are limitations of and arguments against using field experiments in place of other research designs (e.g. lab experiments, survey experiments, observational studies, etc.). Given that field experiments necessarily take place in a specific geographic and political setting, there is a concern about extrapolating outcomes to formulate a ...

  7. Limits of computation - Wikipedia

    en.wikipedia.org/wiki/Limits_of_computation

    The Bekenstein bound limits the amount of information that can be stored within a spherical volume to the entropy of a black hole with the same surface area.; Thermodynamics limit the data storage of a system based on its energy, number of particles and particle modes.

  8. Bradford protein assay - Wikipedia

    en.wikipedia.org/wiki/Bradford_protein_assay

    The Bradford protein assay (also known as the Coomassie protein assay) was developed by Marion M. Bradford in 1976. [1] It is a quick and accurate [2] spectroscopic analytical procedure used to measure the concentration of protein in a solution.

  9. Bioassay - Wikipedia

    en.wikipedia.org/wiki/Bioassay

    A bioassay is an analytical method to determine the potency or effect of a substance by its effect on living animals or plants (in vivo), or on living cells or tissues (in vitro).
