Abstract

The present describes a system and method for determining the concentration of tetrahydrocannabinol (THC) including a tray comprising a first analyte including an infusion of a solvent and cannabis, a light emitting element configured to illuminate the first analyte, a light receiving element configured to receive a first light transmitted through the first analyte, and a control circuit configured to calculate a concentration of tetrahydrocannabinol in the first analyte based at least in part on the first light.

Claims

1. A system, comprising:

a tray comprising a first analyte including an infusion of a solvent and cannabis;

a light emitting element configured to illuminate the first analyte;

a light receiving element configured to receive a first light transmitted through the first analyte; and

a control circuit configured to calculate a concentration of tetrahydrocannabinol in the first analyte based at least in part on the first light.

4. The system of claim 1,

wherein the tray comprises a top portion and a bottom portion;

wherein the bottom portion is configured to lock to the top portion using a locking feature.

5. The system of claim 4, wherein the top portion or the bottom portion comprise:

at least one alignment feature configured to uniformly vertically space the top portion from the bottom portion.

8. The system of claim 1, further comprising a display configured to display the concentration of tetrahydrocannabinol in the first analyte.

9. The system of claim 1, wherein the light emitting element comprises at least one light emitting diode.

10. The system of claim 9, wherein the light receiving element comprises at least one photodiode.

11. The system of claim 10, wherein the at least one light emitting diode is configured to emit ultraviolet light.

2. The system of claim 2,

wherein the tray comprises a first cavity to contain the first analyte and a second cavity to contain a second analyte including the solvent only.

3. The system of claim 2,

wherein the light emitting element is further configured to illuminate the second analyte in the second cavity;

wherein the light receiving element is further configured to receive a second light transmitted through the second analyte; and

wherein the control circuit is further configured to calculate the concentration of tetrahydrocannabinol in the first analyte based at least in part on the first light and the second light.

6. The system of claim 2,

wherein the first cavity or the second cavity comprises an optically clear material.

7. The system of claim 2, wherein the first cavity or the second cavity comprise a substantially convex surface.

12. An apparatus, comprising:

a tray configured to contain a first analyte comprising an infusion of tetrahydrocannabinol and a solvent;

a light emitting device configured to generate a light to illuminate the first analyte contained in the tray with a light;

a light receiving device configured to receive a first portion of the light transmitted through the first analyte; and

a control circuit configured to determine a concentration of tetrahydrocannabinol in the first analyte based at least in part on the first portion of the light transmitted through the first analyte received by the light receiving device.

13. The apparatus of claim 12,

wherein the tray is further configured to contain a second analyte comprising the solvent without tetrahydrocannabinol;

wherein the light emitting device is further configured to illuminate the second analyte contained in the tray with the light;

wherein the light receiving device is further configured to receive a second portion of the light transmitted through the second analyte; and

wherein the control circuit is further configured to determine the concentration of tetrahydrocannabinol in the first analyte based at least in part on a comparison of the first portion of light to the second portion of light received by the light receiving device.

14. The apparatus of claim 12,

wherein the tray comprises a top portion and a bottom portion;

wherein the top portion or the bottom portion comprise at least one locking feature, at least one horizontal alignment feature, or at least one vertical registration feature.

15. The apparatus of claim 14,

wherein the at least one locking feature is configured to lock the top portion to the bottom portion;

wherein the at least one horizontal alignment feature is configured to horizontally align the top portion relative to the bottom portion; and

wherein the at least one vertical registration feature is configured to vertically space the top portion from the bottom portion.

16. The apparatus of claim 12,

wherein the tray further comprises a first cavity to contain the first analyte and a second cavity to contain the second analyte.

17. The apparatus of claim 16, wherein the first cavity or the second cavity comprises an optically clear material having a substantially biconvex outer surface.

18. The apparatus of claim 12, further comprising a display configured to display the concentration of tetrahydrocannabinol in the first analyte.

19. The apparatus of claim 12,

wherein the light emitting device comprises at least one light emitting diode;

and

wherein the light receiving device comprises at least one photodiode.

20. A method, comprising:

illuminating a first analyte with ultraviolet light, the first analyte comprising a solvent and tetrahydrocannabinol;

measuring a first portion of the ultraviolet light transmitted through the first analyte;

illuminating a second analyte with ultraviolet light, the second analyte comprising the solvent;

measuring a second portion of the ultraviolet light transmitted through the second analyte; and

determining a concentration of tetrahydrocannabinol in the first analyte by comparing the first portion of the ultraviolet light transmitted through the first analyte to the second portion of the ultraviolet light transmitted through the second analyte.
