Unfortunately this.It has nothing to do with the sample you sent, it's just a warning to say that their method is not precise. anyway it does not test the purity of the powder
Like I spoke elsewhere a while ago, if FTIR was a reliable tool for testing like this, I'd use a 5000$ FTIR with zero running costs instead of a 50k$ HPLC which eats through 1k$ of solvents a month...
