LIDOS-3004 Series Thermal Desorption Analyzer

⒈Core analytical technology: it is provided with a Peltier-cooled cold trap, supports pre-desorption mode, and can detect C₂-class VVOCs; Valve oven rated to 350℃ for high-temperature operation, covering VOCs and SVOCs, eliminating residual high-boiling components, with an analytical range of C₂ to C₄₄.

⒉Structural and maintenance advantages: the gas-tight metal chamber requires no septa consumables, and needle-free operation avoids cold spots; Purge gas consumption is low, which further reduces maintenance costs; An inert-coated cold trap combined with gas-line filtration provides a low instrument background.

⒊Automation and throughput: 72 sample positions for continuous operation; It provides online automatic dry purging and automatic conditioning of desorption tubes, requires no additional conditioning equipment, and is suitable for high-moisture samples and calibration curve preparation.

⒋Sample handling functionality: with sample splitting, high-concentration samples can be split, stored, and retained for reanalysis; Internal standard addition shows good stability, with RSD < 2%; Compatible with desorption tubes from multiple brands and specifications, and features built-in calibration and leak-check functions.

⒌Application: it is used for trace VOC/SVOC analysis in ambient air, occupational hygiene, material emissions, and scientific research, and can be connected to gas chromatographs and GC-MS.

⒍Configuration and standards: standard configuration includes main unit, cold trap, 50-position autosampler, adsorption tubes, and chromatographic interface; It meets EPA TO-17 VOC testing standard.
