  2. Protein mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Protein_mass_spectrometry

    A mass spectrometer used for high throughput protein analysis. Protein mass spectrometry refers to the application of mass spectrometry to the study of proteins.Mass spectrometry is an important method for the accurate mass determination and characterization of proteins, and a variety of methods and instrumentations have been developed for its many uses.

  3. Mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Mass_spectrometry

    Mass spectrometry. Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions. The results are presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures.

  4. Isotope-ratio mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Isotope-ratio_mass...

    mass spectrometry. Isotope-ratio mass spectrometry (IRMS) is a specialization of mass spectrometry, in which mass spectrometric methods are used to measure the relative abundance of isotopes in a given sample. [1][2] This technique has two different applications in the earth and environmental sciences. The analysis of ' stable isotopes ' is ...

    en.wikipedia.org/wiki/Microsoft_Access

    Microsoft Access. Microsoft Access is a database management system (DBMS) from Microsoft that combines the relational Access Database Engine (ACE) with a graphical user interface and software-development tools. It is a member of the Microsoft 365 suite of applications, included in the Professional and higher editions or sold separately.

  6. Source lines of code - Wikipedia

    en.wikipedia.org/wiki/Source_lines_of_code

    Source lines of code. Source lines of code (SLOC), also known as lines of code (LOC), is a software metric used to measure the size of a computer program by counting the number of lines in the text of the program's source code. SLOC is typically used to predict the amount of effort that will be required to develop a program, as well as to ...

  7. Seismic magnitude scales - Wikipedia

    en.wikipedia.org/wiki/Seismic_magnitude_scales

    A "broad-band" variant (Ms_BB, M s (BB)) measures the largest velocity amplitude in the Rayleigh-wave train for periods up to 60 seconds. [44] The M S7 scale used in China is a variant of M s calibrated for use with the Chinese-made "type 763" long-period seismograph. [45] The MLH scale used in some parts of Russia is actually a surface-wave ...

  8. Tandem mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Tandem_mass_spectrometry

    A quadrupole time-of-flight hybrid tandem mass spectrometer. Tandem mass spectrometry, also known as MS/MS or MS 2, is a technique in instrumental analysis where two or more stages of analysis using one or more mass analyzer are performed with an additional reaction step in between these analyses to increase their abilities to analyse chemical samples. [1]

  9. Air pollution measurement - Wikipedia

    en.wikipedia.org/wiki/Air_pollution_measurement

    Air quality monitoring sensors in Port Pirie, South Australia. Air pollution measurement is the process of collecting and measuring the components of air pollution, notably gases and particulates. The earliest devices used to measure pollution include rain gauges (in studies of acid rain), Ringelmann charts for measuring smoke, and simple soot ...
