Yes, In nic from vendors such as ecx, heartlandvapes, vice's etc. and i'm guessing mfs...
It is very high quality nic just as clean as e.g. nude-nicotine and vapers-tek nic, but whereas those mentioned nics often are "invisible" i.e. no real smell/taste, then nicselect nic ussually has a slight wodden/nutty/damp-tobacco'y smell/taste, which is pleasant for unflavored or tobacco mixes, but which some don't like in e.g. fruit/dessert mixes. However, It can easilly be masked and many high-quality
eliquid-makers are using nicselect e.g. nicoticket etc.
Here's one of there latest coa, btw:
Nicotine USP Batch 469102604040
All coas i've seen from them(~20) has an anhydrous assay purity of 100.0% to 100.5%. Of course you cannot get any purity over 100%, but that's just to account for the unprecision of the meassuring tool, so the spec dictates up to 101% to account for that. Also anhydrous assay takes other alkaloids into the same result, but those are really really small anyway with this nic...
Alchem is a real "giant/leader" in the nic-business, with batch-sizes of 250.000 liters of 99.97+ pure nic a a time, and I believe nicotine river is an authorized nicselect reseller in the states, so that's why it's so cheap, compared to many other smaller ventures, i'm guessing...
Btw, some time ago, there where some issues with nicselect smelling/tasting "rubbery", but that hasen't been reported in a long time. They(alchem), state that they had some issues previously with maintaning a "uniform" product with all the different crops of tobacco's and different aging of them and which part of the leaf used and what the used tobacco had drawn up from the soil, which imparted the smell/taste of some batches, but that they had sorted out the kinks since long...
I'm vaping unflavored nicselect right now making this post
