Let me preface this thread by mentioning that I am aware of and have skimmed the many storage threads in PD, including the B&D one. As far as I can tell, though, the question that I am about to raise has not been comprehensively answered anywhere.
I was wondering if there is any benefit to putting AL-LAD l-tartrate powder into a solution for long-term storage, vs. just putting the powder in a small, air-proof glass vial and storing it that way. I do not have argon gas (or any other inert gas) available, so deoxygenating the vial is not an option. I know that exposure to oxygen is a no-no, though I am not sure if the risk is significant given the small and constant amount of oxygen in the vial.
As far as the solution is concerned, I would be using either distilled water or ethanol, or a mix of the two. I don't suppose that something like e.g. 80 proof vodka would be a good choice, but I'll be happy to be corrected on this.
The plan is, obviously, to store the vial in a freezer.
Which method will work better for protecting the substance against degradation?
