Le Bulletin ISA CALGARY SHOW Special Edition ONLINE GAS ANALYZER EXPERTS New product range for hazardous areas hromatotec has developed new ranges of auto-GCs and process-GCs for hazardous area operation. This allows Chromatotec to expand its markets and deploy its expertise in online gas trace and ultra-trace level analysis of VOCs and sulfur compounds. Now many configurations of Chromatotec GC866 Exp (pressurized) and/or Exd (flameproof) are available with different levels of certification: • ATEX and IECEx: zone 1, Group IIC or Group IIB + H2 T4. • CSA (in the USA and Canada): Class 2 Division 2 Group B, C & D T4. MEDOR® Exp or Exd allow online sulfur measurement in natural gas, gaseous fuels and ambient air. The amount of applications has increased, from H2S at ppb level with H2S MEDOR to sulfur speciation including odorants and total sulfur at ppb or ppm range with energyMEDOR. By adding a specific injection valve, we can go to a high concentration at high ppm or % or to a liquid application for LPG analysis. Easy track, a user-friendly odor and chemical dispersion modeling software, that uses weather conditions and site topology, can be included. ISA Calgary Show Calgary, Canada 9-10 April 2019 - Booth 216 PEFTEC Rotterdam, Netherlands chromaPID or airTOXIC allow online VOCs measurement with our analyzer in Exp version. Thanks to these processGC analyzers using PID detection we can analyze Benzene alone at ppm level for hygiene or quality control of gases. BTEX and Styrene in ambient air can be monitored in hazardous areas at ppt and ppb levels for air quality monitoring and many VOCs per request. Online gas compositions and specific applications can be performed using our chromaTCD and/or chromENERGY which are auto-GCs with TCD detection. Natural Gas Odorization Houston, USA 27-28 August 2019 - Booth 7 Many options are available in a type of certification which allow high versatility of the GC866 Ex such as multiplexing, temperature regulation, 24 V DC, inbuilt nitrogen generator, internal calibration and on site computer access without opening the cabinet. Complete speciation of sulfur compounds in hazardous area zones I and II using Ex d certified solution atural gas is a natural resource present deep below the surface of the earth. In order to use and valorize natural gas, it is necessary to control its composition, which can vary depending on where it is extracted. Even if it is composed mainly of methane, natural gas contains some traces of sulfur compounds which can affect its quality and can have dramatic effects for its transportation (e.g. corrosion of the pipes). Therefore, companies that work with natural gas control the level of sulfur compound impurities as well as adding specific Mercaptans to make it odorized and easily detectable in case of a leak. (requesting hydrogen and air for the flame and big volume of purge gas to operate in hazardous areas) used for sulfur compounds detection. Chromatotec®’s energyMEDOR appears to be the best solution for these applications since it only needs a very small amount of zero air or nitrogen to operate (down to 4 mL/min) and its MEDOR® wet cell Sulfur Specific Detector is capable to detect sulfurs as low as 1 ppb. For this purpose, Chromatotec® has developed and manufactures the energyMEDOR® which measures with speciation all following sulfur compounds generally present in the natural gas: H2S, DMS, DMDS and Mercaptans. This new instrument is designed to work in hazardous areas such as ATEX zone 1 without any purge gas requested for operation. The MEDOR Ex d solution is one of the only instruments capable to analyze all previously mentioned sulfur compounds in hazardous areas without purge gas thanks to the MEDOR® wet cell detector. Other possibilities given to customers are using the FPD technology This certified solution has been designed to operate in zone I and II and can be used with 230V, 115V and 24V DC power supply making it quite unique on the market.

Chromatotec®, specialist in the manufacturing of process gas analyzers for online monitoring, is now entering the world of liquid sample analysis through the development of a simplified enhanced liquid sampling system (XXvalveLPG) specifically designed to extract representative samples from the liquid phase. The extracted liquid sample is vaporized and injected in continuous mode into the column of the auto-GC analyzer with speciation of more than 16 sulfur compounds or 123 Volatile Organic Compounds (VOCs) according to the configuration type. Considering sulfur compounds approach, H2S,...
