Advanced sample handling and conditioning

JCT ANALYSENTECHNIK GMBH has developed new advanced components for sample gas handling and conditioning for continuous gas analysis systems (CEMS and Process). These include new sample probes for hazardous areas (ATEX Zones 1 and 2) with operation temperature of up to 180 °C, new sample handling systems for total mercury analyzers, as well as the sample gas conditioner JCS-100 with the most advanced heat exchanger JHEX4 with the proven lowest wash-out rate of water soluble compounds (SO2, NO2).

The sample probes models JES-360, JES-370, and JES-370 Dual for NH3 and NOx analysers enable continuous sampling even at extremely high dust concentrations above 1000 g/m³. The probe includes all components are heated to temperatures up to 315 °C (safely above 225 °C below which ammonia salts are formed, clogging sample tubes and filters with crystalized salts). The NH3 analyser is connected to high temperature (> 250 °C) heated sample lines at the hot filter outlet. For NOx analysis the sample gas from a second filter outlet first passes through an ABS filter, effectively removing ammonia salts.
