I think I will be going the Na2CO3 route next time in the hope of cutting out the filtering step. This may make the Tek more appealing to some. But for now I don't think it needs too much fine tuning unless one is trying to experiment with pulling other harmala alkaloids or getting a purer product etc.

(I definitely need to try a mini EA A/B at the end to see if it can be cleaned up a bit more.)

Everyone experiments and finds Tek's that work form them, now I may be bias but for now I personally favor this approach. There's always room to fine tune later down the track as well.

I would think there are likely impurities in there but one can't be sure the ratios or amount without a lab test. There may even be very few impurities, who knows. Since there's no manske and depending on citric acids binding ability, there is also the slim possibility that other harmala alkaloids may also be present. So there could be a trade off there.

In any case there's likely a good ratio of harmaline and harmine. But what this experimenting has reinforced is that EA is a good method for pulling harmala. And other's may want to adapt this to their own Tek going forward.

There's a chance someone may even work out how to crash out harmalol from the EA or get a pure product by changing acids or bases etc. Who knows.
