2. Spectrum analyzer - Wikipedia

   en.wikipedia.org/wiki/Spectrum_analyzer

   A spectrum analyzer is also used to determine, by direct observation, the bandwidth of a digital or analog signal. A spectrum analyzer interface is a device that connects to a wireless receiver or a personal computer to allow visual detection and analysis of electromagnetic signals over a defined band of frequencies.

3. Spectrochemistry - Wikipedia

   en.wikipedia.org/wiki/Spectrochemistry

   Spectrochemistry is the application of spectroscopy in several fields of chemistry. It includes analysis of spectra in chemical terms, and use of spectra to derive the structure of chemical compounds, and also to qualitatively and quantitively analyze their presence in the sample.

4. Optical spectrometer - Wikipedia

   en.wikipedia.org/wiki/Optical_spectrometer

   In general, any particular instrument will operate over a small portion of this total range because of the different techniques used to measure different portions of the spectrum. Below optical frequencies (that is, at microwave and radio frequencies), the spectrum analyzer is a closely related electronic device. Spectrometers are used in many ...

5. Spectrometer - Wikipedia

   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.

6. Inductively coupled plasma atomic emission spectroscopy

   en.wikipedia.org/wiki/Inductively_coupled_plasma...

   ICP Plasma "torch". The ICP-AES is composed of two parts: the ICP and the optical spectrometer.The ICP torch consists of 3 concentric quartz glass tubes. [2] The output or "work" coil of the radio frequency (RF) generator surrounds part of this quartz torch.

7. Spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Spectroscopy

   Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of astronomy, chemistry, materials science, and physics, allowing the composition, physical structure and electronic structure of matter to be investigated at the atomic, molecular and macro scale, and over astronomical distances.

8. Atomic absorption spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Atomic_absorption_spectroscopy

   Atomic Absorption Spectroscopy (AAS) measures the concentration of specific elements in a sample by analyzing their unique "fingerprint" in the form of an atomic absorption spectrum. Here's how it works: Step 1: Sample Preparation:** The sample is typically dissolved in a suitable solvent (acids, water) to create a liquid solution.

9. 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.
