I don't have one sorry, it's an assumption I've made based on the results I observed. I'm only a brewer with relatively limited knowledge when it comes to the chemistry involved. Do you have any possible ideas as to what has caused increased DO levels in the samples?

I probably should have taken control samples with only Brewtan added to water and taken measurements. I should possibly redo this experiment, seeing what impact brewtan alone does to O2 levels in a sample of water.

I am starting to experiment with 30 mg/l SMB + 30 mg/l BB in my water and so far I haven't taken any DO readings, but anecdotally the wort was just as bright and full flavored (maybe the flavor was even a hair better) as the rest of my LoDO batches that used SMB only.
I'd be interested if you or anyone else receives similar results, and to be honest I've done multiple lodo batches utilising Brewtan B and had great results also.

Re: Brewtan
I've not messed with it yet, but did try a beer from a friend's commercial brewery over the weekend that he was playing with brewtan in. In his ipa it turned 2 row and a bit of c60 into straight marris otter. It really turned an ipa into a nice malty pale ale .

Tanal-a on the other hand is a great product to keep wheat beers turbid, I have used it with much success. It pays to have a commercial account and go right though wyeast
What changed?

This was pre-low oxygen( the years ago comment, before it was brewtan b). So once I stopped oxidizing my beer, things can now be noticed.

0.37 g/gal is the supplier recommendation and gives 50 ppm Meta if I remember correctly. You have to watch the Dose with Antioxin because of the Potassium though.
When I came up with the concept and term of the LODO Trifecta, I looked for commercial sources first. Most listed their chemicals on their MSDS sheets, but not their ratios. I have been mixing mine individually from day one. I target the blends to the beer style, water composition, yeast strain, fermentation temperature and desired flavor profile.

Good to hear. A bunch of people from the AHA forum who have started to adopt the methods are having great luck with their custom blends as well. There is quite a bit of freedom there.
