microanalysis
Sign in to saveMicroanalysis is the chemical identification and quantitative analysis of very small amounts of chemical substances (generally less than 10 mg or 1 ml) or very small surfaces of material (generally less than 1 cm2). One of the pioneers in the microanalysis of chemical elements was the Slovenian-Austrian Nobel Prize winner Fritz Pregl.

Microanalysis is the chemical identification and quantitative analysis of very small amounts of chemical substances (generally less than 10 mg or 1 ml) or very small surfaces of material (generally less than 1 cm2).

== Methods == The most known methods used in microanalysis include: Most of the spectroscopy methods: ultraviolet–visible spectroscopy, infrared spectroscopy, nuclear magnetic resonance, X-ray fluorescence, Energy-dispersive X-ray spectroscopy, Wavelength-dispersive X-ray spectroscopy, and mass spectrometry Most of the chromatography methods : high-performance liquid chromatography, Gel permeation chromatography; Some thermal analysis methods: differential scanning calorimetry, thermogravimetric analysis; Electrophoresis; Field flow fractionation; X-ray diffraction; Combustion analysis.
