Common Testing Procedures

Below, we delve into the essential testing procedures and the requisite equipment for a comprehensive cannabis analysis:

• Sample Preparation: Preparing cannabis samples for testing depends on their initial state and intended application. Labs may examine cannabis products in various forms, such as dried flowers, cannabis extracts, concentrates, and edibles, each necessitating a slightly distinct sample preparation regimen.
  
  
• Cannabinoid Analysis: To quantify key cannabinoids like THC, CBD, and CBN, standard methods of analysis include High-Performance Liquid Chromatography (HPLC) and Gas Chromatography (GC).
  
  
• Terpene Analysis: Terpenes, renowned for their aromatic properties and medicinal attributes, play a pivotal role in cannabis. Common analysis methods encompass Gas Chromatography/Mass Spectrometry (GC/MS), Gas Chromatography with Flame Ionization Detection (GC/FID), and HPLC.
  
  
• Heavy Metal Detection: Cannabis products can potentially contain heavy metals such as cadmium, mercury, lead, copper, tungsten, and arsenic. Essential tools for heavy metal testing include Mass Spectrometry, as well as techniques like Inductively Coupled Plasma Mass Spectrometry (ICP/MS), Inductively Coupled Plasma Optical Emission Spectrometry (ICP/OES), and Atomic Absorption Spectroscopy (AAS). Liquid chromatography, although less common, is effective for testing arsenic.
  
  
• Pesticide Testing: Pesticides employed by growers can pose health risks if residues linger in the final product. Commonly used techniques for pesticide analysis encompass HPLC, GC/MS, and LC/MS. The QuEChERS method is often utilized for sample preparation before LC/MS/MS.
  
  
• Residual Solvents: Solvents used in cannabis extraction, including acetone, ethanol, butane, benzene, and propane, can persist in the final product. A prevalent approach for testing residual solvents involves headspace analysis combined with GC. Other methods include GC with Flame Ionization Detection (GC/FID) and Gas Chromatography/Mass Spectrometry (GC/MS).

Key Considerations for Cannabis Testing and Analysis

• The establishment of a cannabis testing laboratory is primarily influenced by the types of tests to be performed and the testing volume. Adherence to regional regulations is imperative, as these guidelines can vary significantly, especially in the United States where state-specific regulations prevail.
  
  
• Whether you're initiating a new laboratory or expanding operations, Qualitest serves as your all-in-one solution for testing instruments and support. These technologies have been integral in ensuring the delivery of top-quality products to consumers, including compliance with third-party testing regulations, which are mandatory in many regions, although the turnaround time may differ.
  
  
• Testing products before they reach the market is a cornerstone of ensuring quality and customer satisfaction. Varied national laws underscore the importance of testing to meet diverse customer demands. Qualitest products are designed for use in strict compliance with all applicable laws, promoting public safety and facilitating lawful scientific or medical research activities.
