Component testing primarily involves the detection of known ingredients in products, performing qualitative and quantitative analysis on these known ingredients, which is a process of verifying known ingredients. Component testing (including component testing items) is a technical method of analyzing unknown ingredients through spectral charts, commonly utilizing methods such as spectroscopy, chromatography, energy spectrum, thermal spectrum, and mass spectrometry.
Scope of Component Testing:
Metallic Material Composition Analysis: Various iron-based alloys (including stainless steel, structural steel, carbon steel, alloy steel, cast iron, etc.), copper alloys, aluminum alloys, tin alloys, magnesium alloys, nickel alloys, zinc alloys, etc.
High polymer materials: plastics, rubber, inks, paints, adhesives, plastics, etc.
Method of Component Testing:
Weighting Method, Titration Method, Potentiometric Electrolysis, Infrared Carbon/Sulfur Analysis, Spark-Discharge Atomic Emission Spectrometry, Atomic Absorption Spectrometry, Thermogravimetric Analysis (TGA), High-Performance Liquid Chromatography (HPLC), Ultraviolet-Visible Spectrophotometer (UV-Vis), Fourier Transform Infrared Spectroscopy (FTIR), Pyrolysis/Gas Chromatography/Mass Spectrometry (PY-GC-MS), Scanning Electron Microscopy/Energy Dispersive X-ray Spectroscopy (SEM/EDS), Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-OES).
