Graphitised carbon black offers unique selectivity and very little adsorption for alcohol analyses. Two types of CarboBlack supports are available, CarboBlack B and CarboBlack C. CarboBlack B support, with its higher surface area, can hold up to a 10% loading of a non silicone liquid phase. CarboBlack C support can hold up to a 1% loading of a non silicone liquid phase.
- CarboBlack packings are treated with KOH or picric acid for basic or acidic compounds
