LCS Laboratory offers a group of tests for evaluation of adsorbents for air purification. A number of different techniques are employed to extract or remove gasses and volatile solvents from the air. The most common approaches are:
- Physical Adsorption on porous adsorbents. Example: solvent removal cartridges in industrial respirators
- Chemical adsorption. Example: removal of Carbon Dioxide on Soda Lime adsorbent
- Chemical or Catalytic oxidation. Example: Conversion of Carbon Monoxide into Carbon Dioxide
We offer our expertise in analytical, physical chemistry and chemical engineering, to assist you in an independent evaluation of efficiency of your adsorbents.
All tests are performed in packed columns, custom made for your application. Clean air is conditioned to meet your specifications and spiked with a target gas or solvent. As air passes through the adsorbent bed we test air flow for solvent concentration before and after the adsorbent.
Typical process of flow is presented below, where all or only selected tests can be ordered.
- Test setup and validation
- Effect of air velocity or residence time on adsorption efficiency
- Estimation of adsorbent capacity in gram per kilogram
- Measurement of breakthrough air volume in litres per kilogram
- Effect of humidity on adsorption
- Effect of temperature on adsorption
Laboratory tests and chemical analysis of air are performed by our Canadian laboratory. If you’d like to discuss your project or request any other tests, please email us at your earliest convenience. We can also assist you with SDS preparation for your product.
