Factors Influencing Mass Transfer in FI Gas-diffusion Separation Systems

3 Factors Influencing Mass Transfer in FI Gas-diffusion Separation Systems 

Factors influencing the mass transfer and performance of FI gas-diffusion separation systems were studied in detail, and discussed by Karlberg and Pacey [22] using chlorine dioxide as the gaseous analyte. Some important observations mainly based on their results include  

The mass transfer of the gaseous analytes increases with a decrease in sam-ple/carrier flow-rate, particularly when the gaseous analyte is transformed into another irreversible chemical species in the acceptor solution. 

The highest phase transfer factor is obtained when the flow-rate ratio of donor and acceptor streams is one, and decreases with a deviation from unity to either direction. 

Slightly higher peak signals are obtained with the donor and acceptor streams flowing countercurrently than flowing concurrently. But the enhancement is mainly due to a change in peak form and not to an increase in the mass transfer.
