Analytical tube activatorIt is a professional instrument used in the analysis and detection fields such as gas chromatography and mass spectrometry to activate analytical tubes, playing an indispensable role in improving analysis accuracy and sensitivity. It mainly preprocesses the analytical tube by precisely controlling parameters such as temperature and gas flow rate. Under high temperature conditions, combined with specific carrier gases (such as nitrogen and helium) for purging, impurities, moisture, and other adsorbed substances that may exist inside the analytical tube are removed to restore it to its initial clean and highly active state, preparing for accurate adsorption and analysis of the target compound in the future.
It generally consists of heating system, gas control system, temperature monitoring and control system, and analytical tube loading device. The heating system provides a stable and adjustable high-temperature environment; The gas control system precisely controls the flow rate and velocity of the carrier gas to ensure the uniformity and effectiveness of the activation process; The temperature monitoring and control system provides real-time feedback and adjusts the temperature to ensure the accuracy of the activation temperature; The analytical tube loading device facilitates the installation and removal of analytical tubes.
Analytical tube activatorIts application scope revolves around scenarios that require sampling and detection through parsing tubes, including the following areas:
1、 Environmental monitoring field
Volatile Organic Compounds (VOCs) detection
For VOCs (such as benzene derivatives, formaldehyde, olefins, etc.) in the atmosphere, indoor air, and automobile exhaust, activated Tenax, activated carbon, and other adsorption analysis tubes are used to ensure stable adsorbent performance during sampling and avoid residual interference with detection results.
Analysis of volatile compounds in soil and water
Activated analytical tubes are used to collect volatile pollutants (such as halogenated hydrocarbons and petroleum hydrocarbons) in the headspace of soil or water, ensuring the accuracy of the pre-treatment process.
2、 Occupational Health and Safety Testing
Detecting toxic and harmful gases (such as organic solvent vapors, pesticide residues, and chemical reagent volatiles) in the workplace air, achieving efficient adsorption and subsequent analysis of trace pollutants through activated analytical tubes, and providing data support for occupational exposure assessment.
3、 Food and agricultural product safety testing
Analysis of volatile flavor compounds in food
Activation analysis tubes are used to collect volatile aroma components (such as esters and alcohols) in food (such as alcohol, dairy products, fruits and vegetables), to assist in quality identification or traceability.
Pesticide and pollutant detection
Targeting volatile pesticide residues (such as organophosphates and pyrethroids) on the surface or inside of food, as well as volatile substances generated by spoilage (such as amines and sulfides), target compounds are enriched through activated analytical tubes to enhance detection sensitivity.
4、 Industrial Production and Quality Control
Chemical production process monitoring
In industries such as petrochemicals and pharmaceuticals, it is used to monitor volatile intermediates and impurities in production workshops or reaction exhaust gases. Activated analytical tubes ensure the accuracy of real-time sampling and guarantee the stability of production processes.
Material release detection
Detect volatile organic compounds (such as plasticizers and formaldehyde) released from packaging materials, plastic products, coatings, etc., collect the released substances through activated analytical tubes, and evaluate material safety.
5、 Research and Laboratory Analysis
Provide analytical tube pretreatment support for scientific research experiments in fields such as environmental chemistry and analytical chemistry, such as studying the performance of new adsorbents, optimizing sampling and analysis methods for volatile substances, etc., to ensure the reliability of experimental data.
