GemmaCert uses FDA-endorsed technology for easy & accurate cannabis testing.

GemmaCert’s flagship product, the GC-PRO, is a desktop cannabis and hemp testing solution designed for in-house or field testing delivering immediate results with lab-level accuracy.

If a sample tested by a certified lab using high performance liquid performance chromatography (HPLC) results in a THC potency of 10%, then the same exact sample tested by the GC-PRO shall produce a THC potency result between 9% and 11%. Allowing you to identify the potency of your flowers. The correct protocol has to be followed for this comparison.

Near Infrared Spectrometry

Recognized by the FDA and EMA, NIR spectroscopy is used by the pharmaceutical industry for quality control, including product development and testing for regulatory compliance.

Image Analysis / Motion Mechanics

GemmaCert devices extract meaningful information from each sample using digital image processing techniques. The GC contains a camera which provides a precise location of the sample so that the spectrometer is able to scan 24 different spots around the sample. In order to meet the need for heterogeneity.

Machine Learning

Our devices learn and adapt automatically through experience, using algorithms and statistical models to analyze large amounts of data from our comprehensive reference database.

As a professional you must ensure that your products are compliant, consistent, safe, effective, and predictable. In-house testing needs to be an important part of your Standard Operating Procedures.

GemmaCert has developed this innovative solution that analyzes cannabis and provides reliable potency readings, without harming the flowers or altering their efficacy and commercial value.

Growers, dispensaries, labs and home users can use the device to test an unlimited amount of flowers, which spares them the time and costs involved in batch sampling and lab testing.

Our one-of-its-kind device combines 3 technologies: spectrometry, image analysis and data analytics, to provide a real-time, reliable solution for measuring cannabis potency. Results are delivered directly to a proprietary secure app on your smartphone.

GemmaCert Professional makes it easy to perform in-house testing to ensure that your products are effective, consistent, safe, and compliant. We make it easy to consistently deliver a high-quality product.
