Precision Composition Analysis Services

Precision Composition Analysis Services | Third-Party Laboratory Expertise

In modern manufacturing and product development, knowing the exact chemical and material composition of your samples is critical for quality assurance, regulatory compliance, reverse engineering, and failure analysis. As an ISO/IEC 17025 accredited third-party testing organization, we provide unbiased, high-accuracy composition analysis tailored to industries including polymers, pharmaceuticals, metals, specialty chemicals, cosmetics, and environmental monitoring. Our expert team combines classical wet chemistry techniques with advanced instrumentation (FTIR, GC-MS, ICP-OES, HPLC, TGA, DSC) to deliver quantitative and qualitative profiles you can trust.

Whether you need raw material verification, contamination identification, competitor product de-formulation, or full elemental fingerprinting, our independent laboratory follows validated international methods (ASTM, USP, EP, ISO). Every report is reviewed by Ph.D.-level chemists and includes detailed methodology, uncertainty statements, and actionable conclusions. Below you will find our complete testing portfolio and the wide range of sample types we routinely handle.

Comprehensive Composition Testing Items

• Full Quantitative Chemical Profiling – Determination of major, minor, and trace components (wt%, ppm, or ppb levels) using gravimetry, titrimetry, and spectroscopy.
• Elemental Analysis (Metals & Non-metals) – ICP-MS, ICP-OES, XRF, and combustion analysis for over 70 elements, including heavy metals (Pb, Hg, Cd, CrVI) and nutrient elements.
• Polymer & Plastic Composition – Identification of resin type (PE, PP, PVC, PET, PA, etc.), copolymer ratios, filler content (CaCO₃, talc, glass fiber), plasticizers, antioxidants, and flame retardants.
• Organic Compound Identification – GC-MS, HPLC-DAD, LC-MS/MS for complex organic mixtures, additives, residual solvents, and degradation products.
• Impurity & Contaminant Analysis – Root cause investigation of foreign particles, spots, gels, discoloration, or residues via FTIR microspectroscopy and SEM-EDS (when permitted).
• Moisture & Volatile Content Determination – Karl Fischer titration, loss on drying (LOD), thermogravimetric analysis (TGA) for hygroscopicity and process control.
• Metal & Alloy Composition Verification – Percentage of alloying elements (C, S, Mn, Si, Cr, Ni, Mo, etc.) and grade conformity per ASTM E415, E1086.
• Pharmaceutical & Nutraceutical Assay – API purity, excipient composition, dissolution profiling, and forced degradation studies following USP/EP monographs.
• Particle Size & Distribution (affects compositional homogeneity) – Laser diffraction, dynamic image analysis, or sieve analysis for powders, granules, and suspensions.
• Unknown Substance Identification (Deformulation) – Systematic breakdown of multi-component products (coatings, inks, adhesives, detergents) using spectral libraries and wet chemistry.

Acceptable Sample Types for Composition Analysis

Our laboratory accepts a diverse range of sample matrices. Minimum sample quantity depends on the required tests and number of analytes; standard guidelines are listed below. For special materials, please contact our technical team for feasibility and sampling advice.

• Solid Materials (Bulk & Shaped) – Plastics, rubber, metal pieces, ceramics, tablets, films, laminates, composites, and electronic components. Minimum 5 g or 1 cm³ recommended.
• Liquids & Solutions – Aqueous solutions, solvents, oils, emulsions, suspensions, chemical intermediates, and biological fluids. Typical volume: 10–20 mL.
• Powders & Granules – Pharmaceutical powders, pigments, metal powders, detergents, cement, and food ingredients. Minimum 10 g for representative sampling.
• Gels, Pastes & Semi-solids – Cosmetics (creams, lotions), ointments, adhesives, sealants, greases, and thick slurries. Provide 5–10 g in sealed containers.
• Fibers & Textiles – Natural/synthetic fibers, yarns, nonwovens, fabric swatches, and technical textiles. Minimum 0.5 g or one square inch.
• Coatings, Paints & Films – Paint chips, varnish layers, plated surfaces, thin polymer films, and powder coatings. Scrape or delamination methods accepted.
• Biological & Botanical Samples – Dried plant material, herbal extracts, fermentation broths, algae, and animal tissues (with proper preservation and SDS).
• Finished Products & Complex Assemblies – Toys, automotive parts, packaging materials, medical devices, and multi-layer structures. Destructive testing may apply.

Sample submission note: To ensure accurate results, please include a completed submission form with matrix description, suspected components, and any safety data sheets (SDS). We provide custom sampling kits for liquids, powders, and sensitive materials. All samples are stored in secured, temperature-controlled zones and are discarded only upon written authorization.

Our Analytical Workflow for Reliable Composition Data

Every composition analysis project follows a rigorous, traceable process designed to eliminate cross-contamination and bias. Our workflow includes: 1) Sample registration & chain-of-custody → 2) Preliminary visual and FTIR screening → 3) Method selection (classical or instrumental) → 4) Sample preparation (digestion, extraction, dilution, ashing) → 5) Instrumental measurement (calibrated with certified reference materials) → 6) Data processing & statistical validation → 7) Expert technical review and final report generation. Typical turnaround is 3 to 7 business days, with expedited options for urgent projects.

Why Choose Our Independent Third-Party Composition Analysis?
