TROUBLESHOOTING
7. The instrument has a clog. Flush the sample input (Settings Flush System
Clear Sample Input) and then re-start the analysis. For persistent clogs, flush the
instrument forward (Settings Flush System Flush Forward), or backward
(Settings Flush System Flush Backward). Check whether solvent is moving
through the tubing and into the waste bottle. Contact Support if clog persists.
8. The flowmeter calibration has become faulty. In rare cases, the flowmeter
calibration may become degraded. If persistent flow errors are occurring on
multiple samples, contact support.
HIGH ABSORBANCE SAMPLE
Descripon
In rare cases, high concentration samples will cause the instrument to read results
outside of the linear range. If this occurs, the confidence in the results will be degraded.
The likelihood of this happening is highest with samples that contain high CBDA since it
has the strongest signal of the cannabinoids measured.
Causes and Fixes
1. Check to ensure that the extraction was done correctly. Note for concentrates
greater than 35% Three syringe-fulls (30ml) of solvent are required. If
extraction was done incorrectly, re-extract the sample.
2. If extraction was correct, the sample must be re-run after it has been diluted:
a. Shake extracted sample to ensure it is homogenous.
b. Remove 5ml of extracted sample and add to a new extraction vial.
c. Add 5ml of extraction solvent to vial
d. Shake vial for 10 seconds to ensure it is mixed.
