Foreign Material Analysis

Foreign material analysis is a technology that specializes in analyzing the composition of tiny embedded foreign bodies or surface contaminants or precipitates on the product. For example, qualitatively analyze abnormal substances such as foreign bodies, spots, oily substances, and frosts embedded on the surface, so as to find sources of pollution or incompatible formulas, is one of the most commonly used analytical methods to improve products. As a professional reliability third-party testing organization, T,C&A Lab can provide Foreign Material Analysis service according to ISO, ASTM standards and industry requirements. Welcome to contact our experts for consultation.

Application fields of foreign material analysis

Foreign matter analysis technology is usually used in the following situations: the newly produced product has some abnormal defects such as black spots or surface contamination such as oil stains, or after a period of storage, transportation, etc., some tiny spots, oils, powders suddenly appear. At this time, foreign matter analysis methods are urgently needed to analyze what these foreign matter belong to, and then find the source of pollution or pollution link, eliminate it, improve the formulation system, and improve the quality of the product.

Methods for foreign material analysis

Analysis the organic structure of foreign body

Method: Infrared microscope-FTIR

Analysis the elemental composition of foreign body or material surface

Methods: Electron probe (EPMA), scanning electron microscope energy dispersive spectrometer (SEM-EDX), multi-function photoelectron spectroscopy (XPS), energy dispersive micro-area X-ray fluorescence spectrometer (μ EDX) and so on.

Surface observation

Methods: Optical microscope (OM) and electron microscope (such as SEM)
