Sample Preparation
Sample Preparation of Cannabis Products
With changing cannabis regulations, it is important to implement analyses with proper sample preparation considerations. LCTech is an expert in sample preparation for this field. They have a number of applications
posted on their site, including:
• Sample clean-up for the determination of pesticides in cannabis using a non-dispersive QuEChERS method.
• Determination of mycotoxins in hemp using IAC based clean-up columns.
• Determination of THC metabolites in human urine.
