I've read this thread from A to Z. Only a few ideas here taken into account:
A) it's anise, not licorice (absinth flavour?)
B) it's not lemon, but maybe citric acid? (PG/VG diluted)
C) what's this polar separating layer in Pluid? Is it part of anise/absinthe flavor? I tried to vape this separate yesterday from my almost empty Pluid bottle and it's harsh...
As it separates well and I have access to NMR (my girlfriend is working on 500MHz) I'll give her 10mg for analysis

Problem is that it might be quite complex mixture of organic compounds to identify and If you don't know what you're looking for...

Standards would help, but it's time consuming puzzle...
I'd rather pay 7GBP for 10ml Pluid than search for hints for composition everywhere and try to make it DIY.
But there's only one EU vendor selling Pluid once a month for 2 minutes, usually at night.
I'm watching threads discussing this juice, waiting for any stock updates. And I was sooo happy when I succeed 2 weeks ago and purchased 100ml (!) from US libertyflights website. But then they cancelled my order. As they said, they can't ship nicotine to Europe

( (It's strange as I'm buying juices from US almost every week without issues).
So,...I vaped my last 2ml of Pluid in Orion yesterday. Pluid was my all day vape for 1 month (I bought 80ml second hand for crazy price from France). Now is the time to forget this awesome juice and try something else as I'll hardly get some more from UK libertyflights without insane waiting for their stock up.
But I tried Magic Fairy, Black Fairy, Shocker, Black Licorice, own Ouzo mixtures....it's not Pluid
