A new equipment for adsorption and desorption measurements, similar to that suggested in a previous work, was assembled. With this apparatus experiments can be carried out at pressure up to 500 bar at water bath temperatures. The equipment consists of three parts: a high pressure pump, a water bath where the sample column is placed and a UV detector.
The apparatus, tested on the basis of literature data, has been used for adsorption and desorption measurements of a drug (nimesulide) in activated carbon.
