perhaps it makes sense to bring the ph up gradually, allowing time for migration beefore the release of some of the nasty stuff that seems to get released at the high end of ph.
true, 14 won't hurt it, but if you get a blob of soap-like emulsion, it may impede the flow of free base molecules into the np.
This may seem like a good Idea biz but when you consider what comes over first(the emulsion) in slower basing techniques, Ibee finds that sometimes it's better to base the hell out of it with a concentrated solution and act quick on getting that first pull. Now this assumes that gaaks are present!
If they are, a certain percentage will get locked up now matter how the work-up is carried out.
which makes me curious about bottom layer np
wouldn't gravity work in your favor if the np was below?
Not in all cases. When considering that some of the contaminants form the heavier emulsion by weight. The trash will fall down into the NP because of that gravity. This is what makes washing Bottom feeders NP's a necessity! Ask Geez!
Biz....this is why Ibee stresses the importants to remove all gaaks from the picture before rxn, because contaminated work-ups are a bitch even for the seasoned chef and expert reclamation specialists alike.
This is also why more time gets spent on refining extraction methods in Ibees circle than gets spent on rxns.
btw, biz has dreamt of taking a pull of np at 9 or 10, and getting some virgin results. yeah, most of the goods won't bee in that pull, but almost none of the crap will bee either.
i thought this was how anybee managed to stay awake long enough to finnish and clean up an lwr, poky-ass rxn.
Again....if a concentrated lye solution is used, one can get a larger pull on that first one before the majority of gaak has a chance to form. That has been Ibees experience with working with gaaked work-ups! If the gaaks aren't present and cause for concern in the end, the amounts and order of lye addition are no concern as long as the amine gets released when basing
btw, wareami,
should bees fear that sticking a tube thru an upper solution of god only knows what and np, could give bad readings on the ph of the lower layer?
Not really if the emulsion is scooted out of the way when dipping. If that middle emulsion layer is that thick the solution should be filtered before proceeding! Besides, if the solution is gaaked, the emulsion will be in the polar layer and the pH reading won't flucuate by much.
Any NP on the side of the pipette won't hurt because it won't register on the strip! But one could always wipe sides off with a tissue or papertowel before unloading contents onto the strip.
Just dip pipette down to the very bottom to take the few drop testsample, pullout and wipe, then squirt. ;)
swimmy thought so, when forced to talk to himself about all the things that could go wrong.
but it does seem, to swim, that more of the funky crap comes over at the high end of the a/b ph
This is correct with certain gaaks....remove them first before rxn and there is no problem!
If bees need a refresher from Ibee on how to gaurantee removal of OII Gaak then say the word and it will be posted again! Ibee's almost ready to throw down a full write-up from extraction of Everything down to the LWR rxn and finally the getting down to Biz part!
In the meantime, if those gaaks are being dealt with post-rxn, Ibee suggests not prolonging the inevitable. Do this by getting in there and getting what you can on the first pull, brute force basing style, then let the gaaks settle out or experiment getting the rest while you have the added energy from the first lot pulled!
swimmy's titrated pulls were polymer free at the low end of the free basing ph demands.
This opens UP a whole new nest of worms, And after all this, everybody wishes I'd just shut UP....right Os??? ;D
Hope this helps Biz and Bees!
