Odorization at low ppm level: Analysing H2S and mercaptans in natural gas for odorization.
Deodorization at ppb level: Specific sulfur analyses in natural gas post-deodorization. Important for natural gas and LPG companies.
Analysis of odorants in Liquid Petroleum Gas: Gas Chromatography ensures effective analyses directly from the liquid phase for people safety.
Odorization control : ppm
EnergyMEDOR ppm is a proven gas chromatography solution designed for the precise analysis of sulfur-based odorants such as hydrogen sulfide (H₂S) and mercaptans in natural gas and LPG. Used for more than 30 years by major gas companies worldwide, the system ensures reliable monitoring of odorization compounds like TBM, THT, and MES at low ppm levels, helping operators guarantee safety, detect leaks, and comply with international regulations. By providing accurate quantitative speciation of odorants—including direct analysis from the liquid phase in LPG using a dedicated sampling valve—energyMEDOR ppm enables effective control of gas odorization processes across natural gas distribution networks and LPG applications.
Deodorization control : ppb
energyMEDOR ppb is a high-sensitivity gas chromatography analyzer designed to measure and speciate trace sulfur compounds in natural gas at very low concentrations, making it ideal for monitoring gas quality and verifying the efficiency of deodorization processes. Widely used by natural gas producers, transport and storage operators, LPG companies, and industrial gas users, the system provides accurate quantification of hydrogen sulfide and other sulfur species from low ppm levels directly in gas pipelines down to low ppb levels after purification processes such as steam reforming. Its dual-range sampling system automatically switches between different loop volumes to prevent detector saturation while ensuring precise measurements across a wide concentration range.
H2S and Total Sulfur : ppb to %
Chromatotec’s H₂S and Total Sulfur analyzers are designed for continuous monitoring of sulfur compounds in natural gas pipelines to ensure infrastructure integrity and compliance with gas quality standards. Using the MEDOR® sulfur-specific electrochemical detector, the system provides fast and highly sensitive measurements of hydrogen sulfide and total sulfur every two minutes, allowing operators to quickly detect excessive concentrations that could cause corrosion, reduce heating value, or compromise pipeline safety. With low maintenance requirements, long detector lifetime, internal calibration through permeation tubes, and remote monitoring capabilities, the analyzer delivers reliable and efficient sulfur monitoring for natural gas production and midstream operations.
Determination of individual sulfur : ppb to %
Chromatotec provides advanced solutions for the precise analysis and speciation of sulfur compounds in natural gas, biogas, and LPG, where even trace levels can affect safety, compliance, and process efficiency. The energyMEDOR analyzer offers a wide dynamic range from ppb to percent levels, enabling accurate identification of individual sulfur species such as H₂S, COS, mercaptans, and sulfides for both laboratory and online monitoring, while the chromaS COS system is specifically optimized for the sensitive and selective detection of carbonyl sulfide and other sulfur compounds. Together, these instruments deliver robust, high-precision sulfur analysis for applications including gas quality control, environmental monitoring, and industrial process optimization.
Natural Gas / Biogas composition
chromEnergy is an automatic industrial gas chromatograph designed for the precise measurement of hydrocarbons in natural gas and biogas, enabling reliable characterization of gas composition from C1 to C6+ using a Thermal Conductivity Detector (TCD). Integrated with Chromatotec’s Vistachrom software, the system calculates key parameters such as calorific value and Wobbe index, supporting energy quality assessment and process optimization. Its robust and autonomous design—featuring an integrated hydrogen generator, multi-channel capability for up to 32 analysis points, and compact industrial installation options including ATEX configurations—makes chromEnergy a dependable solution for continuous monitoring of natural gas and biogas quality in demanding industrial environments.
Siloxanes control
Chromatotec provides advanced solutions for the ultra-sensitive detection of siloxanes in biogas and landfill gas, compounds that can generate abrasive silica deposits during combustion and severely damage engines, turbines, and energy recovery systems. The chromaFID analyzer enables reliable identification and quantification of major siloxanes such as L2–L5 and D3–D5 at low ppb levels, while the airmoVOC system extends detection capabilities to the ppt range for the most demanding monitoring applications. Together, these instruments deliver highly precise and continuous siloxane analysis, helping operators protect equipment, optimize biogas quality, and ensure compliance with industry and environmental standards.
Terpenes control
Chromatotec provides advanced analytical solutions for the precise monitoring of terpenes in biogas, compounds naturally generated from plant-based organic waste that can cause corrosion, fouling, and reduced efficiency in energy recovery systems. Using the chromaFID and airmoVOC analyzers, operators can accurately detect and quantify individual terpenes such as limonene, α-pinene, β-pinene, myrcene, and terpinolene from ppm down to ppb or even ppt levels. This high-sensitivity analysis enables early detection and effective control of terpene concentrations, helping protect engines and turbines, optimize biogas quality, and maintain reliable and efficient industrial operations.
