Carbotrap® T420 Thermal Desorption Tube: Precise Air Monitoring for Terpene Analysis in Industrial and Environmental Applications

Accurately monitoring terpenes in air is challenging for growers and researchers due to high humidity and the need for non-destructive methods. The Carbotrap® T420 Thermal Desorption Tube delivers reliable terpene sampling and analysis for indoor and outdoor environments, supporting industrial compliance and environmental monitoring needs. As a dedicated Carbotrap T420 Thermal Desorption Tube solution, it is suitable for both research and routine monitoring workflows.

Benefits of Carbotrap T420 Thermal Desorption Tube

• Supports non-destructive terpene profiling of growing and flowering plants using a simple grab air sample, avoiding the need to remove and dry plant material for qualitative analysis.
• Enables air sampling and analysis of terpenes in high humidity environments, including indoor greenhouse growing operations.
• Helps industrial hygiene and indoor air quality programs evaluate terpene and VOC exposure conditions in indoor cultivation environments where workers may experience potential respiratory health effects.
• Provides a practical approach for measuring terpene emissions in environments where there are currently no federal or state government–mandated workplace exposure limits for terpenes.
• Supports outdoor monitoring near growing locations to study and monitor environmental emissions, assess terpene drift, and investigate associated odors.
• Gives regulators a tool for active fenceline measurement around growing operations and neighboring communities to inform odor studies and potential mitigation strategies.
• Applies across multiple terpene-related contexts, including cannabis, hemp, hops, and other terpene-fragrant plants, helping streamline air monitoring across research and operations.

Application and usage of Carbotrap T420 Thermal Desorption Tube

• • Industrial hygiene air sampling for terpenes and other volatile organic compounds (VOCs) in indoor greenhouse environments associated with cannabis and hemp growing and cultivation.
  • Indoor air quality monitoring for terpene emissions in indoor greenhouse environments.
  • Ambient air emissions monitoring.
  • Environmental emissions studies, including fenceline measurement around cannabis and hemp agricultural growing operations and neighboring communities.
  • Terpene drift monitoring and assessment.
  • Terpene odor concentration measurement.
  • Non-destructive live plant profiling using a grab air sample.
  • Sampling of headspace air of plant materials.
  • Indoor terpene profile measurements within cannabis greenhouse growing operations (including flowering plants and dried plant material headspace).
  • Outdoor measurement of terpenes from hemp growing operations.
• How to collect air samples 
  • Pull a known volume of air through the TD tube using an air sampling pump during the sampling event.
  • Calculate total sample volume by multiplying the flow rate (L/min) by the sampling time (minutes).
  • Use a recommended sample collection volume between 0.10 and 10 liters to help prevent breakthrough and overloading of the analytical system.
• Recommended sample collection volumes by application 
  • Testing of live plants and headspace of the actual plant material (Observed terpene odor: Very strong): 0.1 to 0.2 liters
  • Indoor sampling of greenhouse (Observed terpene odor: Strong): 1 to 2 liters
  • Outdoor sampling near growing location (Observed terpene odor: Detectable): 2 to 5 liters
  • Outdoor sampling (Observed terpene odor: Undetectable): 5 to 10 liters
  • Note: Terpene odor thresholds will differ among users.
