It is very important to have tools that help industry to have quick answers. GC is unique in the cannabinoids field as it doesn’t need any special technical requirements to operate it or any type of sample preparation before analysis (beyond drying and grind).Ana Matias, Lead Scientist – Clever Leaves
I wanted a reliable tool to test the correct levels of THC and CBD in our cannabis flowers. I love the App – easy to use and very helpful.Youri Florijn, Manager – Prix d'Ami
We test all of our hemp genetics with GemmaCert starting 30 days before expected harvest date. This helps us for THC risk mitigation and optimize CBD levels. Also turns out that the soils and actual weather has a big influence on hemp biomass and cannabinoid production.Alan Boyce, Executive Chaiman at Materra Hemp Farming Company (California, USA)
Our team uses GemmaCert devices in all of our facilities for various purposes. For example quick pheno-hunting testing, tracking how grow conditions effects cannabinoid development, and determining optimal harvest times. We have compared results to our in-house HPLC and GemmaCert is very accurate.Michael Waisman, Head Agronomist at Tikun Olam (Israel)
We have racked up well over a thousand analysis with the GemmaCert in just a few months. Very accurate and reliable. Should be in every LP!Daniel Gagne, IPM Supervisor at Verdelite (Canada)
This is a great instrument. For pheno-hunting, ROI on this unit is about 3 days. Great support as well!Stewart Maxwell, Crop Consultant at Xylem Horticulture (Canada)
We have used GemmaCert to generate our development documentation. Fast, easy and reliable measurements of individual flowers -secures maximum knowledge.Medican, Linda Bech Pihl, QA Specialist, M.Sc Chemical Engineering and six sigma black belt
The GC-PRO is simple, easy-to-use, fast, and accurate.
No special skill-set is needed to test cannabis with the GC-PRO.
After an easy and quick onboarding, you can use your GC-PRO to test your cannabis and get accurate results on the spot, including for THC and CBD potency levels.
The GC-PRO is used worldwide to test cannabis and hemp.
Satisfied and loyal customers across the supply chain in 50 countries include:
GemmaCert uses FDA-endorsed technology for easy and 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%.
The GC-PRO THC potency test kit is used for flower potency testing, ground material (biomass/trim), and crude extract. All that is needed for operation is a smartphone with Internet connection.
Every new GC-PRO customer is invited to a short onboarding session with a member of the GemmaCert Team to ensure successful adoption and implementation of best practices.
Once up and running, GemmaCert customers benefit from over-the-air updates which improve performance and introduce new testing features. As time passes, the GC-PRO performs better and delivers more.
The GemmaCert device enables real-time potency, composition and quality analysis of the cannabis plant by non-destructive means, including the identification and quantification of primary active compounds, such as ∆9-Tetrahydrocannabinol (THC), Cannabidiol (CBD), and Cannabigerol (CBG). The GemmaCert device is perfect for in-house and field testing because it is fast, low-cost, easy-to-use, no sample preparation is required, portable, non-destrutive, eco-friendly, and you can also print a Certificate of Analysis (CoA) after each test.
The GemmaCert device uses a Near-Infrared Spectrometer (NIRS). NIRS is an FDA-endorsed diagnostic technology for evaluating the identity, strength, quality, purity, and 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. NIR spectroscopic analysis is fast, requires no sample preparation, and can analyze multiple parameters with a single measurement. The technology addresses the major requirements for a suitable analytical method that is rapid, suitable for high-throughput analysis, on-site capability, chemical specificity, and minimal sample preparation.
Test the same exact sample for THC potency on the GemmaCert device and then on an HPLC: if the HPLC result is 10% THC potency, then the GemmaCert device’s result will be between 9% and 11%. The minimum THC detection limit is 0.2%. The GemmaCert device 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.
The GemmaCert device tests for THC, CBD, CBG, and Water Activity (Aw). From time to time, software updates are released with new measurement capabilities.
The GemmaCert device is a great tool for measuring breeding progress, determining the optimal harvest time, mitigating the risk your crop is harvested above the legal potency thresholds, pre-checking samples before mandatory testing for regulatory compliance, confirming incoming cannabis raw materials matches the purchased specification, measuring extraction efficiency, determining if your cannabis product is safe for storage or transport, and more.
Yes, the GC app is compatible with Android only. We reccomend a dedicated smartphone/tablet for testing so you aren’t interupted with calls during analysis. Any basic/inexpensive Android with Wifi & Bluetooth cappabilities is suitable Additionally, in the future, an iOS app shall be released as well.
Both an HPLC and NIRS are considered secondary techniques. They need prediction models needs to be created before they can be used to analyse a sample. To identify or quantify a substance with an HPLC, the laboratory needs to prepare standard solutions of the substance and measure them to create a calibration curve. With NIRS, the prediction model is created processing spectra with known concentrations or known parameter values with the aid of chemometric software tools.
No, flowers must be dried to below 12% moisture content before analysis on GemmaCert. That said, we do have a reccomended protocol for wet flower analysis in which buds can be rapid dried in under 24 hours and tested (link to protocol)
We have collected over 15,000 cannabis & hemp samples from a wide range of potencies (sourced from North America, Europe & Israel) which have been measured first in a GemmaCert device and then immediately thereafter in our ISO 17025 certified HPLC lab. This makes up our validated cross-referenced database (calibration standard). We are constantly adding additional data which helps us improve performance and expand features over time.
That said, the term “calibration” can be confusing as it is often applied to different processes. In summation, we perform a final calibration before shipping the device out. Aside from that there is a 20 second auto-calibration before each analysis. There is no need for periodic\manual calibrations or anything of the sort.
The GemmaCert device is our “all inclusive” package which includes the GC device, all accessories (flower pin, ground holder, extract holder) and the protective pelican case. You enjoy all future feature/software updates with no recurring or consumable fees whatsoever. The GC-Lite can only test whole flowers (no option for ground or extract) and only tests down to a minimum threshold of 1% THC. Additionally, it does not come with the Pelican case
