Resistivity/Conductivity Analysis and Testing Services

Resistivity/Conductivity Analytical Service is suitable for measuring conductivity-related properties of materials, including resistivity, sheet resistance, surface resistance, resistance, and contact resistance. Applicable material forms include solids, thin films, coatings, powders, and liquid slurries.

Testing Range:

• Low-Resistance Meters: Typically used for testing conductive materials such as metals, graphene, and graphite with resistance <100 kΩ.
• High-Resistance Meters: Used for less conductive materials such as plastics and fabrics, with a resistance range of 100 kΩ to $10^{14}$ Ω.

Application Fields:

Semiconductors, lithium batteries, solar cells, fuel cells, new energy technologies, graphite and carbon materials, graphene, ITO films, conductive glass, rubber and plastic materials, insulation, and antistatic industries.

Sample Requirements:

• Powder Samples: Particles should be as uniform as possible. A mesh size of ≤40 is recommended (finer particles are acceptable), and the maximum size should not exceed 10 mesh. At least 1 mL of sample by volume is required.
• Bulk/Solid/Thin Film Samples:
  • For conventional low-resistance samples, the length should exceed 1 cm.
  • For high-resistance samples (e.g., antistatic/epoxy materials), vertical bulk resistance requires a diameter >50 mm, and surface resistance requires >80 mm.
• Liquid Samples: A minimum of 10 mL is required.
• Gel Samples: If the sample is difficult to remove, the container’s opening should have a diameter >2.5 cm, or the sample should be level with the container opening.
• Fiber Samples: The recommended length is >3 cm, and the fibers should not be too brittle. Diameter information must be provided.
• Volume Resistance Testing: The sample surface must be flat and smooth; otherwise, poor contact may result in inaccurate testing results.
• Battery Bipolar Plates/Carbon Paper: Refer to the instrument details for specific requirements.
