The Fentanyl Threat Is Evolving

Illicitly manufactured fentanyl and its analogs — carfentanil, acetylfentanyl, furanylfentanyl — are now the leading driver of overdose deaths in the United States. A lethal dose can be as small as two milligrams, invisible to the naked eye and undetectable by smell.

Traditional colorimetric field tests require officers to open packaging and handle unknown powders, creating direct exposure risk. The Serstech Arx mkII eliminates that risk entirely with non-contact, through-packaging detection.

Purpose-Built for Fentanyl Identification

Through-Packaging Detection

Identify fentanyl and analogs without opening the bag, envelope, or container. Eliminate officer exposure to airborne particles.

Results in Under 60 Seconds

Rapid spectral analysis delivers a confirmed identification in the field — no lab wait times, no chain-of-custody delays for initial screening.

10,000+ Substance Library

The onboard library covers fentanyl, carfentanil, all major analogs, cutting agents, and novel psychoactive substances updated regularly by Serstech.

Court-Admissible Reports

Every scan generates a timestamped, GPS-tagged PDF report exportable via ChemDash — ready for prosecutorial use.

Mixture Detection

Identify multi-component mixtures common in illicit supply chains — fentanyl cut with xylazine, benzodiazepines, or other adulterants.

Most Affordable in Class

The Arx mkII delivers enterprise-grade fentanyl identification at a price point accessible to departments of all sizes — no large agency budget required.

How It Works in the Field

01

Aim at the Suspect Substance

Point the Arx mkII at the packaging or container. No sample preparation, no opening, no contact required.

02

Pull the Trigger

The 785nm laser fires a safe, eye-protected scan through the packaging material and into the substance.

03

Read the Result

The onboard display shows the identified substance, confidence level, and any detected mixture components within seconds.

04

Export the Report

Sync with ChemDash to generate a court-ready PDF report with timestamp, GPS coordinates, and officer ID.
