Perceptol and Microdol-X are based on D-23, purportedly with slightly less Metol, and the addition of Sodium Chloride. Microdol-X included an anti-silvering/plating agent.
RLS is a MQ developer, which is not the same thing. Further, there is nothing inherently abnormal about the keeping properties of D-23 type developers once mixed, not are they prone to any kind of inherent "sudden death".
RLS is a different formula and is packaged as a liquid. A one-part liquid developer requires careful formulation and packaging if it is to have a long shelf life.
If your developer smells like ammonia, then something is probably wrong. Test it by using a small piece of film that's been exposed to light before developing something important.
I hope you find a solution to your problem.
hi , i have the same problem just few seconds ago !
rollei 80s 50 iso in rls 1+4 24°c 12.5 min . I believe that is a failure in the composition of the developer in the factory... the rollei film is the agfa aerial film aviphot pan 80 .... and is a wonderful film (in rodinal) .
So film-fix-stop from agfa gavaert (belgium) and developer from rollei (cg 512 formula) ..... it's the developer !
I wonder if the original OP, fatso, ever contacted Rollei? If he didn't then not telling Rollei of his issue hasn't done Rollei or other customers such as Aldo any favours.
Frustrating when an OP doesn't bother to gives us closure to an issue on which collectively APUGers devoted their time
Thanks Pentaxuser , i live near (30KM) the italian dealer .. so i'll make some inquiry !
i believe that is an old problems with some Lot ( in italian i mean lotto ... in english is better stock ? )
i love the infinity life of rodinal .. for that !
