    en.wikipedia.org/wiki/Spectrometer

    An XPS spectrometer. A spectrometer (/ s p ɛ k ˈ t r ɒ m ɪ t ər /) is a scientific instrument used to separate and measure spectral components of a physical phenomenon. Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed.

    en.wikipedia.org/wiki/Optical_spectrometer

    An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. [1]

    PMI is a portable method of analysis and can be used in the field on components. [2] X-ray fluorescence (XRF) PMI can not detect small elements such as carbon. This means that when undertaking analysis of stainless steels such as grades 304 and 316 the low carbon 'L' variant can not be determined.

  6. Spectrum analyzer - Wikipedia

    en.wikipedia.org/wiki/Spectrum_analyzer

    Handheld spectrum analyzer. This form factor is useful for any application where the spectrum analyzer needs to be very light and small. Handheld analyzers usually offer a limited capability relative to larger systems. Attributes that contribute to a useful handheld spectrum analyzer include: Very low power consumption.

  7. Spectrophotometry - Wikipedia

    en.wikipedia.org/wiki/Spectrophotometry

    Spectrophotometry is a branch of electromagnetic spectroscopy concerned with the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength. [2] Spectrophotometry uses photometers, known as spectrophotometers, that can measure the intensity of a light beam at different wavelengths.
