Concentration Determination

 

Precise quantification of substance composition to drive quality assurance and regulatory success.

Concentration is the most fundamental parameter in chemical analysis, defining the purity, efficacy, and safety of a substance. At Weshin Inspection Tech , we offer a comprehensive suite of analytical services to accurately quantify target components in liquid, solid, or gaseous matrices.


The Importance of Concentration Testing

 

Accurate concentration data is the cornerstone of technical dossiers and commercial quality standards:

  • Quality Control (QC): Verifying that active ingredients in chemical products, cosmetics, or industrial agents meet specified labels.

  • Regulatory Compliance: Providing essential data on active ingredients and impurities for REACH, GHS, and agrochemical registrations.

  • Safety & Risk Assessment: Measuring residual levels of hazardous substances (e.g., heavy metals, VOCs) to ensure compliance with environmental and occupational standards.

  • Process Optimization: Monitoring the concentration of reactants and products during manufacturing to enhance yield and consistency.
     

Our Analytical Methodologies

 

Weshin Inspection Tech utilizes a range of advanced techniques tailored to the required detection limits:

  • Instrumental Analysis:

    • Chromatography (HPLC / GC): For the quantitative analysis of organic compounds, additives, and pesticide residues.

    • Spectroscopy (UV-Vis / ICP-OES): Determination of metal elements, ionic concentrations, and specific functional groups.

  • Wet Chemistry (Titrimetry): High-precision measurement of acidity, alkalinity, redox potential, and hardness.

  • Physical Characterization: Rapid estimation of solution concentration via Refractive Index, Density, or Gravimetric methods.
