X-Ray Fluorescence Spectrometer
XRayFluorescenceSpectrometer
Purpose: X-ray fluorescence (XRF)  is a non-destructive analytical technique used to determine the elemental composition of materials. XRF spectrometers determine the chemistry of a sample by measuring the fluorescent (or secondary) X-ray emitted from a sample when it is excited by a primary X-ray source. Each of the elements present in a sample produces a set of characteristic fluorescent X-rays ("a fingerprint") that is unique for that specific element, which is why XRF spectroscopy is an excellent technology for qualitative and quantitative analysis of material composition.

X-Ray Diffractometer (XRD)
XRayDiffractometer
Purpose: X-ray powder diffraction (XRD) is an analytical technique primarily used for phase identification of a crystalline material and can provide information on unit cell dimensions. The analyzed material is finely ground and homogenized. XRD is more widely used for the identification of unknown crystalline materials (e.g. minerals, inorganic compounds). Determination of unknown solids is critical to studies in geology, environmental science, material science, engineering and biology.

Mossbauer Effect Spectrometry (MES)
MossbauerEffectSpectrometry
Purpose: PNRI has the only MES system in the Philippines. Mossbauerspectroscopyis a versatile technique used to study nuclear structure with the absorption and re-emission of gamma rays. The technique uses a combination of the Mossbauer effect and Doppler shifts to probe the hyperfine transitions between the excited and ground states of the nucleus. Mossbauer spectroscopy requires the use of solids or crystals which have a probability to absorb the photon in a recoilless manner, many isotopes exhibit Mossbauer characteristics but the most commonly studied isotope is57Fe which is what is studied at PNRI.
