Cannabinoid sample assessment: Concentrated or Diluted sample

SAMPLE ASSESSMENT

Whether your sample has a low or high rate of cannabinoids, you can calculate a multiplication factor in order to be able to test a low THC rate from hemp or a high rate from concentrate. Just apply this simple rule based on the weight of your sample:

Concentrated samples (high cannabinoid concentration)

In case of high concentration samples where you expect between 40% and 100% CBD for example you will take 40mg of samples with 1µl extraction fluid with the suitable capillary tube then:
Multiplication factor = (100 mg x 2ul) / 40 (mg) X 1 (µl) = 5
Then after spot calibration of the plate, if your chart shows 13% CBD multiply by 5, you will actually have 65% CBD in your sample.

Diluted samples (low cannabinoid concentration)

In a case of low concentrate samples where you expect between 0.1% and 5% THC for example, you will take 200mg of samples with 8µl extraction fluid with the suitable capillary tube, then :
Multiplication factor = (100 mg x 2ul) / 200 (mg) X 8 (µl) = 0.125
Then after spot calibration of the plate, if your chart shows 5% THC multiply by 0.125, you will actually have 0.6% THC in your sample.

See more examples in the tables below:

Potency testing for cannabinoid samples from 1 to 40% (Flowers, Hash, other, …) Potency testing (4 sample product / plate)

Chemotype testing for main and secondary cannabinoid (CBN, THCV, CBG, CBC) for sample below 40%  THC/CBD testing + Acid form (1 sample product/plate)

How to measure the cannabinoid acid form?

For exemple:  if you obtain 16% THC (LANE 1) and 5% THC (LANE 3), then  16% – 5% = 11% of THCA in your sample.

Chemotype testing for main (THC, CBD) and secondary cannabinoid (CBN, THCV, CBG, CBC) for samples above 40% (Concentrated oil, Ice O lator…) Potency testing + Acid form (1 sample product/plate)

How to measure the cannabinoid acid form?
For exemple:  if you obtain 66% THC (LANE 1) and 15% THC (LANE 3), then  66% – 15% = 51% of THCA in your sample.

Concentrated sample: For accurate results make sure to use a high precision scale to weigh a minimum of 1mg (0.001g).
Without you cannot guarantee the exact percentage of the results.

Chemotype testing for cannabinoid samples below 1% (Hemp) Potency testing + Acid form (1 sample product/plate)

How to measure the cannabinoid acid form?
For example:  if you obtain 1% THC (LANE 1) and 0,5% THC (LANE 3), then  1% – 0,5% = 0,5% of THCA in your sample.

How to conduct cannabinoid testing without sending samples to a laboratory?

You can conduct cannabinoid tests by yourself (without sending samples to a lab) with Alpha-cat Cannabinoid Testing Kits.

Our testing kits are in full compliance with the guidelines of the World Health Organization concerning the safety and quality of medicinal plant materials (WHO/PHARM/92.559) and can be used to detect the presence of 6 cannabinoids (CBD, CBN, THC, THCV, CBG, CBC).

The Alpha-cat Mini Cannabinoid Testing Kit includes 8 test kits and our Regular Cannabinoid Testing Kit has 40 test kits. And if you test cannabinoid levels on a regular basis, the Alpha-cat Portable Cannabinoid Testing Mobile Lab can perform up to 400 tests.

Find out more in our How To Test My Cannabinoids guide or contact us to find out which cannabinoid testing kit will be the best option for you.
