Non-Destructive Fingerprinting of Compounds


Drug Formulations & Precursors:

Simple, Low-Cost
Compact XRD-XRF
Minimal Sample Prep

All drug formulations have a unique fingerprint of both active and inactive ingredients that identifies the efficacy and brand of each drug. Incorrect formulations containing foreign or substitute ingredients can jeopardize a patient's well-being. Additionally, when incorrect or counterfeit formulations are distributed under a brand name, the reputation of the manufacturer is at risk. Drug manufacturers must protect their business interests by ensuring that the correct formulations of their products are being distributed. This will ensure that patients are receiving the correct formulation, that their branding isn't compromised by counterfeiters, and that they have documented fingerprint records of all their drug and formulation steps. A non-destructive fingerprinting method for drug formulations is essential for pharmaceutical manufacturers. It offers factual support for patent and other legal records as well as retention of the original powder material if needed.

BTX testing a sample

A drug formulation, at any stage, can be quickly scanned for its fingerprint by measuring its crystalline structure. Pharmaceutical fingerprinting is commonly done using XRD. The BTX combines both XRD fingerprinting and XRF elemental ID to perform rapid, thorough identification with its unique sample handling system that leaves the formulation intact for further or future testing.

Operation of the BTX is as EASY as 1, 2, 3

BTX sample chamber

1. Place powdered drug into holder

2. Insert sample holder into BTX

3. Press "Start" to record fingerprint

Popular Male Enhancement Drug Formulation Fingerprints from Two Different Distribution Channels

comparison data of drug components
The red fingerprint is the manufacturer's correct formulation of the male enhancement drug. The blue fingerprint is marketed as the same male enhancement drug and distributed on the internet. It is actually gypsum and contains no active ingredient for the male enhancement drug at all.

Phase Analysis data
Available phase identification pattern matching software provides a complete analysis using either publicly available diffraction pattern databases or common commercially available databases, such as PDF2/PDF4.
