  2. Analytical quality control - Wikipedia

    en.wikipedia.org/wiki/Analytical_quality_control

    Quality control begins with sample collection and ends with the reporting of data. [4] AQC is achieved through laboratory control of analytical performance. Initial control of the complete system can be achieved through specification of laboratory services, instrumentation, glassware, reagents, solvents, and gases.

    The National Institute of Radiological Sciences hospital established in 1961 is a research hospital with a basic focus on radiation therapy. [2]In 1993, the HIMAC (Heavy Ion Medical Accelerator in Chiba) of NIRS was launched, and in 1997 the Research Center for Charged Particle Therapy was opened as one of the leading medical centers using carbon ions are in operation.

  4. Near-infrared spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Near-infrared_spectroscopy

    Near-infrared spectroscopy is, therefore, not a particularly sensitive technique, but it can be very useful in probing bulk material with little to no sample preparation. The molecular overtone and combination bands seen in the near-IR are typically very broad, leading to complex spectra; it can be difficult to assign specific features to ...

  5. Fourier-transform spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Fourier-transform_spectroscopy

    Fourier-transform spectroscopy (FTS) is a measurement technique whereby spectra are collected based on measurements of the coherence of a radiative source, using time-domain or space-domain measurements of the radiation, electromagnetic or not.

  6. Analytical chemistry - Wikipedia

    If the amount in the sample is below an instrument's range of measurement, the method of addition can be used. In this method, a known quantity of the element or compound under study is added, and the difference between the concentration added and the concentration observed is the amount actually in the sample.

  7. Sample preparation in mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Sample_preparation_in_mass...

    The first and most important step in sample preparation for mass spectrometry is determining what phase the sample needs to be in. Different ionization methods require different sample phases. Solid phase samples can be ionized through methods such as field desorption, plasma-desorption, fast atom bombardment, and secondary-ion ionization.

    The National Center for Agricultural Utilization Research (NCAUR) (sometimes still called the Northern Lab; known locally as the Ag Lab) is a United States Department of Agriculture laboratory center in Peoria, Illinois. The Center researches new industrial and food uses for agricultural commodities, develops new technology to improve ...

  9. Functional near-infrared spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Functional_near-infrared...

    This toolbox is a set of Matlab-based tools for the analysis of functional near-infrared spectroscopy (fNIRS). This toolbox defines the +nirs namespace and includes a series of tools for signal processing, display, and statistics of fNIRS data. This toolbox is built around an object-oriented framework of Matlab classes and namespaces. [18]
