Hi,
I noticed that undeveloped Pt/Pd solution tends to get brown and practically useless with time, even if kept in darkness.
I just coated some test strips with high contrast Na2 Pd solution, pretty expensive stuff, but I cannot use them for a week - so I thought, would refrigerating/freezing help?

Thanks

Combine the solutions and coat "right before exposure" for best results and consistency...

my experience is that once these papers are coated they should be used within 24 hours.

Freezing would help -- but do not expect the exact same responce after thawing.
