Nitrogen (N2) and helium (He) transmission rate of films and sheeting
Determination of the nitrogen or helium transmission rate of plastic films and sheet-like materials with the manometric method. Testing is performed on three parallel samples.
Measurement conditions (temperature and relative humidity) can be chosen according to the intended use of the material. Please disclose the desired temperature (from 5 °C to 95 °C) and relative humidity (either 0% or from 10% to 90%) upon ordering.
Oxygen (O2) and carbon dioxide (CO2) transmission rates can also be determined with the manometric method upon request, but the following, more cost-efficient measurements are used more often:
- Suitable sample matrices
- Polymeric films and sheets with smooth surfaces. Maximum thickness 3 mm.
- Required sample quantity
- Three sheets sized 12 cm x 12 cm. Preferably a few extra samples in addition to these.
- Typical turnaround time
- 3 weeks after receiving the samples
- Detection limit
- 0.05 - 50 000 cm3/(m2 × 24h x 0.1MPa). Can be extended up to 500 000 cm3/(m2 × 24h x 0.1MPa)
- Available quality systems
- Measurlabs validated method
- Standard
- Method expert
