What is Alphacat?

AlphaCAT is a Cannabinoid Analytical Tool which combines the simple analytical technique of thin-layer chromatography (TLC) with specific thin-layers and developing fluid.

Cannabis Test Finger Print

Thanks to this new protocol the main active ingredients of the cannabis plant parts can be visualised due to a highly specific colouring reaction which represent the cannabinoids present in the sample of cannabis or cannabis product. AlphaCAT‘s method enables the detection and identification of six (6) of the main cannabinoids present in cannabis:

  • Cannabidiol (CBD)
  • Cannabinol (CBN)
  • Tetrahydrocannabinol (THC)
  • Tetrahydrocannabivarin (THCV)
  • Cannabigerol (CBG)
  • Cannabichromene (CBC)

A minimal amount of material (0.1 gram) is needed per sample to provide a unique and effective way of analysing the cannabinoid profile in complex mixtures such as plant parts of cannabis, trichome resins, oils, tinctures and edibles products (ice-creams, cookies, teas…).

AlphaCAT helps you to assess the effect of any specific strain with:

  • A THC and CBD reference chart for indication of strength and potency
  • Chemotype / cannabinoid profile which categorizes the strain
  • Chemotype-effect chart indicateing the  pharmacological effect to be expected
  • A symptom-cure guide helping to determine which strain best helps to alleviate specific symptoms.

The AlphaCAT Test Kits

MINI kit AlphaCAT

2 plates

Number of tests*:

– THC analysis: 8

– Chemotype prints: 2


10 plates

Number of tests*:

– THC analysis: 40

– Chemotype prints: 10


100 plates

Number of tests*:

– THC analysis: 400

– Chemotype prints: 100

*Each TLC plate allows for testing 4 lanes. A full analysis uses all 4 lanes for 1 strain. To get a chemotype print of your strain, 1 line is sufficient: 4 strains can therefore be analysed on 1 TLC plate.

The following should be supplied by the user

  • Samples of cannabis or cannabis products (e.g. cookies, ice, cake, etc.)
  • Disposable container for spraying dye-solution on a TLC plate, e.g. cardboard box
  • A well ventilated working area (a fume hood connected to a filtering system is recommended)
  • Digital weighing scale

Alphacat Testing Protocol

The AlphaCAT assay solves the issues involved with simultaneously separating  cannabinoids in a simple, cost-effective way, providing a chemical profile for each sample. The AlphaCAT method separates some of the neutral and acidic cannabinoids which are rendered distinct from each other with bright colored spots.

The chemotype profile shows the number of cannabinoids and their relative concentrations. The higher the concentration the bigger and more intensely coloured the spot is. AlphaCAT gives the opportunity to determine the  cannabinoids present in each material sample and reveals the  levels of each individual cannabinoid present in terms of its concentration.

The AlphaCAT method enables anyone regardless of scientific background to define the active cannabinoid profile in medicinal materials (flower, resins, vapor, joints, ‘’brownies’’ and all other derived products).

How to analyse the results

After colouring the TLC plate by dipping it in a dye solution colored spots will appear immediately. The number of different spots depends entirely on the plant used (genetics) and the environmental parameters during cultivation. The bigger the spot is, the higher is the concentration.

The combination of different spots is called the chemotype of this particular plant (strain). Samples derived from it, such as the dried flower blossoms (sinsemilla), edibles, joints, oils and hashish will differ somewhat in composition and won’t show the same cannabinoid profile (or print). Each colored spot on the plate represents a cannabinoid.

The combination of all cannabinoids present in a particular strain will be responsible for the pharmaceutical effects as well as the side-effects commonly reported and will range from an ultimate high feeling/experience (only THC present) to a heavy, “stoney”, “narcotic” sleep provoking strain with low THC when compared to its levels of CBD and CBG or with overall high levels of CBD and CBG. Small differences in cannabinoid levels of THCV, CBG and CBC between strains results in tremendous differences in perceived effect.



Safety Recommandation

  • AlphaCAT® kits are in full compliance with the guidelines of the World Health Organisation concerning safety and quality of medical plant materials (WHO/PHARM/92.559).
  • Our methods meet the guidelines and recommendations of the Food and Agriculture Organisation (FAO) Codex Alimentarius.
  • All of our kits comply fully with Hazard Analysis Critical Control Points (HACCP) guidelines.

AlphaCAT’s kits contains bottles of chlorinated hydrocarbons, labelled as hazardous and the following precautions should be observed at all times:
