As some know I am trying Gas Burst development.

I am not a chemist and wonder about degradation of developer and fixer from Gas Burst operations. Advice, thoughts?
I observe most call the process Gas Burst, not N2 Gas Burst and all systems I have researched have 2 pressure systems, one N2 and one compressed air.


Specifically, I am using compressed air with one shot Rodinal @1/100 10 minutes. 55-10 second off, 1 second on cycles. It seems to me that one shot developer does not need N2 gas as the developer will last the cycle.

I am more concerned about TF5 Fixer as I reuse it from a 4 gallon tank and test with film for clear speed before each use. Plenty of scrap X-Ray around here.

Will my rather complete aeration of TF5 with compressed air degrade it quickly? Am I contaminating or weakening my storage fixer tank reserve? I use 1 gallon out of 4 and dump it back in.

I suppose I will find out empirically.

Will I get longer usage from TF5 or any fixer by using N2 for Gas Burst?

In the future I may go to a developer replenishment system. Will I really need N2 for Gas Burst. Or not?

Theorists and user input highly desired.

Thanks in advance.
