Sample Preparation Checklist
Sample preparation is the most important component in measuring accurate results with your Cann-ID system. When preparing your sample, please make sure to follow each of these steps carefully:
- Calibrate your balance daily before using it.
- Ensure that the balance is stable and the doors are closed before taring the balance and before recording the sample weight.
- Vortex the sample in the sample extraction vial until thoroughly mixed.
- Sonicate flower samples for 10 minutes at room temperature and oil samples for 15 minutes at room temperature.
- Vortex the sample regularly after sonicating.
- When transferring the sample from the green vial to yellow, and yellow vial to blue, make sure of the following:
- A new tip is used for each transfer
- The tip is primed three times with the solution being transferred before performing the transfer
- When drawing up the first solution, the plunger is depressed only to the first stop
- When dispensing from the micropipette depress the plunger to the second stop (as far as the plunger can be pressed down)
- Once transferred, wash the tip in the second solution three times
- If you are using a manual injector: Ensure that the sample loop has been washed 8 times with 50 uL of methanol wash solution before injecting the sample solution
