If you’re producing or processing hemp in Georgia, you already know that lab testing isn’t optional it’s the foundation of compliance, safety, and quality assurance. Two of the most critical tests required by state regulations are for residual solvents and pesticides.
These tests aren’t just about passing inspection they protect consumers and your business. So how exactly are residual solvents and pesticides tested in hemp products? And what do you need to know to avoid failed results?
Let’s take a closer look at how certified labs in Georgia handle this important part of hemp testing.
Why Are These Tests Required?
The Georgia Department of Agriculture requires that consumable hemp products meet specific safety standards. That includes showing they are:
- Free from harmful pesticide residues
- Free from unsafe levels of residual solvents (leftover from the extraction process)
Products that fail either test may be rejected for sale, flagged for remediation, or even destroyed.

Part 1: Testing for Residual Solvents
Residual solvents are chemicals used during extraction, particularly when producing oils, concentrates, tinctures, or vape cartridges. Common solvents include ethanol, butane, propane, and hexane.
What Labs Look For
- Presence of solvents that shouldn’t be there
- Amount remaining in the final product (measured in parts per million or PPM)
- Whether levels are within safe limits set by the U.S. Pharmacopeia or Georgia state law
How It’s Tested
Most certified cannabis testing labs in Georgia use Gas Chromatography with Mass Spectrometry (GC-MS) to identify and quantify residual solvents.
Step-by-step overview
- Sample Preparation: A small amount of the hemp extract is dissolved in a solvent.
- Injection: The solution is introduced into the gas chromatograph.
- Separation & Identification: The system separates the compounds and flags any residual solvents.
- Quantification: The system measures how much of each solvent is present.
Why This Matters
Even trace amounts of some solvents can be harmful if inhaled or ingested. This test ensures products are safe and legally compliant before going to market.
Part 2: Testing for Pesticide Residues
Pesticides are often used in cultivation but when not properly regulated or cleared before harvest, they can end up in the final product. Georgia requires hemp products to be free from harmful levels of pesticides, especially those banned for food or inhalable products.
What Labs Look For
- Detection of dozens of pesticide compounds
- Whether concentrations exceed state safety thresholds
How It’s Tested
Pesticide testing typically uses Liquid Chromatography with Mass Spectrometry (LC-MS/MS), a sensitive method that can detect even trace levels.
How the process works
- Sample Extraction: The hemp material is processed to extract potential pesticide residues.
- Analysis: The extract is run through the LC-MS/MS system.
- Reporting: The lab identifies any pesticides and compares their levels to Georgia’s safety thresholds.
Why This Matters
Some pesticides can become toxic when heated or concentrated, especially in vape or edible products. Testing ensures that the end product is safe for consumers and meets agricultural and health standards.
Testing is also a legal requirement in Georgia. Learn more about licensing in our post Do I Need a License to Sell Hemp in Georgia?
What Happens If a Product Fails Either Test?
If a batch of hemp fails a residual solvent or pesticide test, it can’t be legally sold or distributed in Georgia. Options may include:
- Remediation (removing contaminants through reprocessing)
- Retesting after corrective action
- Destruction if the product can’t be corrected
Products that fail and are sold without correction may lead to fines, license suspension, or loss of credibility, which is why regular, reliable testing is so important.

How to Avoid Failed Tests
- Use approved pesticide products and follow best practices during cultivation
- Ensure proper flush periods before harvest
- Work with experienced extractors using clean extraction methods
- Choose a certified cannabis testing lab in Georgia for consistent, accurate results
- Test multiple samples from each batch, not just a single portion
