surprise B&W sheets in E6 development, dev contaminated?

Hello all, I've tried searching for this and haven't managed to find anything significant, maybe something I'm doing wrong with how I'm phrasing this or just google that doesn't find anything anymore, so -> new post, apologies upfront.

 

Tonight I've developed 4 sheets in Cinestill CS6 (E6 stuff) believing that the four of them were all Ektrachrome E100, but two actually turned out to be Rollei Retro 80S, loaded at least 11 years ago but shot recently (believing they were E100).

"After all that darkness the couple saw some light, only to fall forever wasted."

 

I'm left with another run for the working solution of the developer to exhaust fully, but is it now contaminated?

What about the rest of the chemistry? Colour reversal and Blix?

Do I risk losing or messing up the next four slides, should I just throw the mix away and mix a new working solution?

 

I could just try a Fuji control strip, but that would skew the exhaustion of the developer, and would end up mixing anew just to be sure.

 

Thanks all

How did the B&W sheets turn out, got an image on them?

The faintest, the bleach obliterated whatever developed during the first dev.

 

The other two E100 in the same tank are ok, if a bit dark, but that's likely a result of exposure and Cinestill E6 development, on a light pad they're quite ok.

 

Photo chemicals are not contaminated! OK to use unless oxidized or exhausted. B&W film won't harm.

For E6, you adjust the development times based on the number of rolls (or sheets) processed previously.

 

As well as I know, the adjustments will be the same for your 80S, but maybe a little different.

 

Bleach and fix might be used at a different rate, but should be close enough.

 

The way I always used E6 was two 135-36 rolls per 8 oz.

 

I don't know the numbers for sheet film.
