I have Hydroxylamine HCl, can it be used instead of HAS?

I improved my process, details are in other replies, I wonder if this is effective?

With the current formulation being what it is, can I still add HAS to the solution? If so, which solution should I add it to?

Because sodium sulfite is easily oxidized, I added 1.5g disodium EDTA, 1.5g phenolphthalein and 7g sodium bicarbonate to liquid A. Studies have shown that these ingredients can effectively inhibit the oxidation of sodium sulfite. I wonder if this can extend the shelf life?

Thank you very much. I divided the concentrated developer into three parts (liquid A + liquid B + CD3 powder). Liquid A contains sodium sulfite and sodium bromide, and the rest of the ingredients are in liquid B. Mix them with CD3 before use, which should be effective in extending the shelf life...

我按照柯达的说明书配制了ECN-2溶液（漂白液的配方是C-41），里面含有柯达抗钙剂NO.4和AF2000，如果我把ECN-2原液按照5倍浓度配成浓缩液，它的保质期是多久？
