Method for the $250 identity, purity and quantity test: Chromatographic assay, with detection selected for the compound, against a reference standard, with results in 3 to 5 business days.
The USP monograph covers identity by infrared spectroscopy, specific gravity and a chromatographic check for methanol, strength by specific gravity, organic impurities by chromatography, and nonvolatile residue, UV absorbance, acidity and appearance tests. Full testing to the USP Alcohol monograph is available and quoted.
Chromatographic purity and mg per unit by the method matched to the compound, identity against a reference standard. 1 unit.

Purity and quantity is $250 per sample (1 unit) and raw powder purity is $200 for 50 mg, with results in 3 to 5 business days. Send the material sealed and labeled, with the label claim and the form it contains.
No. The $250 test covers identity, purity and quantity by a chromatographic assay, with detection selected for the compound. Full testing to the USP Alcohol monograph is available and quoted.
Ethanol is volatile and has no useful UV absorbance, so the lab uses a detection method suited to the compound. The test gives the ethanol content and the volatile impurities in one run.
Yes. Methanol is the impurity of most concern in alcohol and is resolved from ethanol in the chromatographic test, along with other volatiles such as acetaldehyde and higher alcohols.
Yes, and the denaturants usually show up as extra peaks. Tell us the stated formula, since denatured grades will not match the monograph.
