Main technical indicators of thermal desorption analyzer
Thermal desorption analyzerThis series of products with wide applicability and reliability is an upgrade based on the certification of the Ministry of National Defense and chemical warfare agent testing. Thermal desorption analyzer is usually connected to GC or GC/MS, and can achieve * sensitivity by enriching air samples (which can range from a few minutes to several hours). The thermal desorption analyzer can achieve near real-time sampling through a heated sampling pipeline, mass flow controller, and vacuum pump. Other applications of the thermal desorption analyzer include: pollution source emission detection, quantitative detection for remediation and repair of polluted sites with increasingly low concentration requirements, detection of health hazards in workplaces, detection of health hazards for emergency personnel in chemical spills and terrorist attacks.
By using high-capacity sampling tubes,Thermal desorption analyzerCapture and thermally analyze target compounds for GC or GC/MS analysis. The analyte is enriched and focused in a high-precision capillary trap, allowing for sharp chromatographic peaks without the need for splitting, cooling below ambient temperature, or low-temperature focusing. The secondary capture and analysis process of the thermal desorption analyzer provides greater efficiency for on-site collection and analysis of atmospheric pollutants.
