Carbon Analysis

Contract Carbon Nano- and Microparticles Analysis

After over 15 years of work with carbon nanoparticles, we have elaborated standard methods of materials characterisation on various parameters, making our products of highest quality and reproducibility. Today you can benefit from our experience letting us test your materials in our lab.

Analytical report is generally emailed as a PDF file to speed up transmission to the client and in parallel per post.

1. Ash content

value is obtained after burning a sample at 900°C on air. Typical reporting limit is 0.005 wt.% (for a 10 grams sample).

2. Non-cubic (sp2) carbon

determination is done by a specific oxidation of a non-diamond carbon. Typical reporting limit 0.2 wt.% (for a 1 gram probe)

3. Determination of particles´ size and distribution

in aqueous media is performed using Photon Correlation Spectroscopy (PCS). The sample is disintegrated by ultrasound prior to measurement. Concentration of a colloid may lay between ca. 0.1 and 60 wt.%. Typical reporting limit 1-1000 nm.

4. Potentiometric titration

of particles surface and determination of the probe´s acidic numbers at pH 8.0 and pH 10.0.

5. Complete analysis

consisting of:

• BET measurement
• Ash content determination
• Non-cubic carbon determination
• Particle size and distribution evaluation
• Potentiometric titration

6. Raman spectroscopy

of carbon on non-carbon nanoparticles (without additional evaluation). Measurement data is supplied in ASCII format.
