Perfect for In-House or Field Testing and On-the-Spot Results

The GC-PRO uses a Near Infrared Spectrometer (NIRS).

NIRS is an FDA-endorsed diagnostic technology for evaluating the identity, strength, quality, purity, and potency of pharmaceutical substances and products.

NIRS is used in many industries for Quality Control.
This includes food and beverage, agriculture, pharmaceutical, dietary supplements, polymers, oil, and gas.

GC-PRO testing marijuana and hemp samples for TCH, CBD potency




The GC-PRO has tested thousands of marijuana and hemp samples for THC, CBD, and CBG potency

These samples were collected from around the world.

Each was cross-checked by testing again using high performance liquid chromatography (HPLC) at GemmaCert’s in-house ISO 17025 certified lab.

The GC-PRO accuracy is boosted by its proprietary 24-point analysis method.

Other solutions on the market apply a single point analysis. This one-and-done method may be quicker, but it is not accurate.

Test the same exact sample for THC potency on a GC-PRO and then on an HPLC
HPLC Result: 10%
GC PRO 24-Point Analysis Result: 9 – 11%
