| Permissible Value(s) | Value | Value Meaning |
| | Attenuated Total Reflectance | Attenuated total reflectance (ATR) is a sampling technique used in conjunction with infrared spectroscopy which enables samples to be examined directly in the solid or liquid state without further preparation. |
| | Emission | The Emission value indicates emission spectroscpy, which examines the wavelengths emitted by atoms or molecules during their transition from an excited state to a lower energy state. |
| | LIBS | LIBS (Laser-Induced Breakdown Spectroscopy) uses a highly energetic laser pulse as its excitation source to produce emission spectra. |
| | Raman | The Raman value indicates Raman spectroscopy, which determines information about a material by studying the Raman scattering of monochromatic light off the material. |
| | Reflectance | The Reflectance value indicates reflectance spectroscopy, the study of light as a function of wavelength that has been reflected or scattered from a material. |
| | Transmission | The Transmission value indicates transmission spectroscopy, the study of light as a function of wavelength that has been transmitted through a material. |
| | X-Ray Absorption Near-Edge Structure | The X-ray Absorption Near-Edge Structure value indicates XANES spectroscopy, which determines information about a material by studying the X-ray absorption spectra of electronic transitions within an atomic core. |
| | X-Ray Diffraction | The X-Ray Diffraction value indicates x-ray diffraction spectroscopy, which studies the diffraction patterns of x-rays scattered off a material. |
| | X-Ray Fluorescence | The X-Ray Fluorescence value indicates x-ray flourescence spectroscopy, which examines the emission of x-rays from a material previously bombarded with high energy x-rays or gamma rays. |
