Testing Samples
Advanced Materials Samples
Materials science projects funded through NSFC programs frequently require characterization of metals and alloys, ceramics, polymers, composites, semiconductors, and functional nanomaterials. Sample forms include powders, thin films, coatings, bulk specimens, fibers, foams, and nanostructures such as nanoparticles, nanowires, nanotubes, and two-dimensional materials. Proper sample preparation, including sectioning, polishing, ion milling, and cryo-fracturing, ensures that analytical results accurately represent the intrinsic properties of the investigated materials.
Chemical and Environmental Samples
Chemistry and environmental science research programs generate samples including catalysts, reaction intermediates, organic synthesis products, water and wastewater specimens, soil and sediment cores, atmospheric particulate matter, and biological extracts. These samples often require trace-level analysis with detection limits in the parts-per-billion or parts-per-trillion range, demanding advanced instrumental techniques and rigorous contamination control throughout the analytical workflow.
Biological and Pharmaceutical Samples
Life science research supported by NSFC funding involves cell cultures, tissue specimens, proteins, nucleic acids, metabolites, pharmaceutical compounds, and drug delivery systems. Testing of these samples requires specialized handling protocols, cold-chain logistics, and analytical methods capable of characterizing molecular weight distribution, purity, secondary structure, and bioactivity.
Energy and Electronic Samples
Research programs in energy storage and conversion involve battery electrode materials, electrolytes, catalysts, photovoltaic materials, and dielectric ceramics. Electronic materials research encompasses printed circuit board substrates, packaging materials, thin-film devices, and microelectromechanical systems requiring dimensional, electrical, and reliability characterization.

Testing Methods
Accredited third-party laboratories deploy a comprehensive suite of instrumental techniques, each selected based on the material class, information depth required, and detection sensitivity specified in the research protocol.
Spectroscopic and Spectrometric Techniques
Elemental composition is commonly determined using inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS) for trace-level quantification, complemented by atomic absorption spectroscopy (AAS) and X-ray fluorescence (XRF) for rapid screening. Molecular structure characterization employs Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, ultraviolet-visible spectroscopy (UV-Vis), and nuclear magnetic resonance spectroscopy (NMR). Surface chemical states are analyzed through X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES).
Chromatographic and Mass Spectrometric Techniques
Organic compound separation and identification utilize high-performance liquid chromatography (HPLC), gas chromatography (GC), and comprehensive two-dimensional chromatographic systems. Coupling these separation platforms with mass spectrometry (LC-MS, GC-MS) enables molecular weight determination, structural elucidation, and quantitative analysis at trace concentrations. Gel permeation chromatography (GPC) provides molecular weight distribution data for polymers and macromolecules.
Microscopy and Structural Characterization
Scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS) delivers surface morphology imaging and elemental mapping. Transmission electron microscopy (TEM) and its variants, including high-resolution TEM (HRTEM) and scanning TEM (STEM), resolve lattice fringes and nanostructures at atomic resolution. Atomic force microscopy (AFM) provides three-dimensional topographical data and local mechanical property mapping. X-ray diffraction (XRD) identifies crystalline phases, determines lattice parameters, and quantifies crystallite size, while small-angle X-ray scattering (SAXS) characterizes nanoscale periodic structures.
Thermal and Mechanical Analysis
Thermal properties are evaluated using thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), and thermomechanical analysis (TMA) following ASTM and ISO protocols. Mechanical testing includes tensile, compressive, flexural, shear, and hardness measurements conducted in accordance with ASTM E8, ASTM D638, ISO 527, and related standards, with additional capability for fatigue, creep, fracture toughness, and impact resistance evaluation.
Surface and Pore Structure Analysis
Gas adsorption analysis based on the Brunauer-Emmett-Teller (BET) method determines specific surface area, while Barrett-Joyner-Halenda (BJH) analysis characterizes mesopore size distribution. Mercury intrusion porosimetry measures macro-porosity, and contact angle goniometry quantifies wettability and surface energy.

FAQ
What information should researchers provide when requesting testing services?
Researchers should submit a detailed testing request including sample description, research background, target analytical information, applicable standards, sample quantity, and any special handling requirements. Providing the relevant NSFC project number and research objectives helps the technical team recommend the most appropriate methods and data presentation formats.
How long does typical testing take?
Standard testing turnaround ranges from three to ten working days depending on the complexity of the technique, sample preparation requirements, and instrument scheduling. Advanced techniques such as TEM with site-specific sample preparation or multi-element ICP-MS workflows may require additional time. Expedited processing is available for time-sensitive project milestones and submission deadlines.
How is research data confidentiality protected?
Accredited third-party laboratories operate under strict confidentiality agreements governing sample handling, data storage, and report distribution. All analytical results are released exclusively to the authorized project contacts, and raw data retention policies comply with data management requirements applicable to publicly funded research.
Can testing reports be used for NSFC project acceptance and publication?
Yes. Reports issued by ISO/IEC 17025-accredited laboratories include method references, instrument parameters, calibration traceability, and measurement uncertainty statements, satisfying the documentation standards required for NSFC mid-term and final acceptance reviews as well as supplementary information requirements of international journals.
What sample quantities are required for each technique?
Sample requirements vary by technique. XRD and BET analyses typically require tens to hundreds of milligrams of powder, SEM may need only a few square millimeters of solid material, while ICP-MS trace analysis can be performed on milligram-scale specimens after digestion. Technical consultants can provide specific quantity guidelines during project consultation to prevent insufficient or excessive sample submission.
Do laboratories assist with data interpretation?
Professional testing laboratories employ application specialists with doctoral-level expertise across materials science, chemistry, and physics who assist clients in interpreting spectra, diffraction patterns, and property data, helping researchers connect analytical results to their scientific hypotheses and publication narratives.
