THT MEDOR

Product catalog summary

Overview: The THT MEDOR® is an advanced gas chromatograph designed for the online analysis and control of gas odorization, specifically targeting TetraHydroThiophene (THT) and Ter Buthyl Mercaptan (TBM) in natural gas and gaseous fuels. It utilizes an autoGC-ED system with a MEDOR® Electrochemical wet cell Detector for precise sulfur compound detection.

Applications: The device is used in odorization processes for continuous monitoring and automatic control of THT levels, with user-definable alarm thresholds and multiple stream analysis capabilities. It also supports deodorization processes with ppb level analysis and automatic alarm generation for catalyzer protection.

Standards and Certifications: The THT MEDOR® complies with ASTM D7493-22, ASTM D7165-22, ISO 19739:2004, and DIN 51855/7 standards. It holds certifications from GOST, ATEX, IECEx, CSA, and CSA International.

Technical Specifications:

Detection Limit: ppm Model – 1 mg/m3, ppb Model – 0.3 mg/m3
Detection Range: ppm model - 1 to 50 mg/m3, ppb model - 0.3 to 3.0 mg/m3
Relative Standard Deviation: RSD < 2% on concentration over 48H, RSD < 0.6% on retention time over 48H
Cycle Time: 180s for one stream, 240s to 300s for multi-stream
Linearity: > 0.995 for all compounds

Features: The system offers automatic calibration, continuous monitoring, and low maintenance with a long-life detector. It includes a powerful VISTACHROM software for remote monitoring and control, with data export capabilities via MODBUS, 4-20 mA, and 0-10 V.

Options: Available options include multiple stream selectors, explosion-proof versions, calculation modules, automatic data transfer, and various power supply and gas supply configurations.

Dimensions and Weight: The standard model is rack-mounted with dimensions of 222mm height, 482mm width, and 600mm depth, weighing 22Kg. The Exp version measures 800mm in height, 600mm in width, and 320mm in depth, with a net weight of 40Kg.
