Outline of Analytical Methods used for Paint Analysis methods for determining the chemical composition of Rolling
The principal methods applied to paintings are chromatographic and spectrometric. Chromatographic analysis of paintings can involve the use of thin-layer chromatography (TLC), gas chromatography (GC) and liquid chromatography (LC).Methods for Determining the Chemical Composition of X-ray fluorescence spectroscopy, or XRF, is a method of PMI that uses low-energy X-rays to scan the chemical composition of alloys. A handheld instrument is used and can determine the composition of the alloy within seconds. The X-rays excite the atoms in the sample, which then fluoresce, producing secondary X-rays that are reflected to the detector. The energy (or wavelength) of these reflected X-rays can be used to precisely determine which elements are contained in the sample.

Rolling of tea shoots initiates oxidation of catechins by polyphenol oxidase (PPO), is responsible for the formation of theaflavins (TFs) and thearubigins (TRs).
How is a material chemical analysis is done?
The analysis is rapid and non- destructive, but is generally impractical for determining elements lighter than fluorine. Samples containing light elements such as lithium and boron for example, are often analyzed by atomic absorption spectroscopy (AAS) or colorimetric methods.See all results for this questionHow are instrumental analytical methods used in rubber making?More complex procedures are used and instrumental analytical methods are applied in chemical analyses of vulcanizates.
