Dear Luisa,

I am also interested in the replies to your question.

My current understanding is that since oxidation and reduction are done in the same reactor, less reagents can be used so the number of samples which may be run before replacing the chemicals is reduced, especially if large samples are used. For me this is not such a problem because I don't need to do commercial work. My understanding is that nothing else is compromised.
 
On the other hand the fact that there is only one reactor tends to produce narrower (& taller) peaks.
 
Hope this helps.

Andrew
