Hi everyone,
we would like to buy some standards of synthetic cannabinoids and NSOs, but Cayman is quite expensive for us (at least for now).
Do anyone have experience with LGC Chemicals distributor and brands like TRC or LoGiCal (sold by LGC)?
Any comments will be appreciated, thank you!
Have a nice day!
I’ve got a solution with an unknown amount of Cu- and Fe-Ions which I need to determine the total mass of. I’ve tried masking the Fe with tartrate to do an iodometry which didn’t work. I’ve also tried to Analyse the amount of iron by doing a KMnO4-titration (Reinhardt-Zimmermann), which also didn’t really work. I’ve been struggling for 3 days on this now, so if anyone knows a good way to do this quantitative analysis, please let me know. Thanks a lot in advance!
