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 Dehydrated Alcohol monograph is available and quoted.
Dehydrated alcohol is nearly water-free ethanol, while USP Alcohol contains about 5 percent water. Water content and specific gravity tell the two apart.
The chromatographic test measures volatile impurities such as methanol, acetaldehyde, acetal and benzene, which can come from production or denaturants.
Ethanol is a small volatile liquid with no UV chromophore, so the lab uses a detection method suited to the compound.
