Sampling loop analysis technology A known volume of the sample stream is repeatedly withdrawn and pushed into the detector using loop sampling. The VOC concentration is proportional to the area under the peak. In this way, we obtain much more stable and accurate results with less maintenance, despite standard systems, which use continuous sample flow capillaries that can become clogged.

Methane - NMHC analysis Performed via packed columns, directly integrated into the instrument. We don't need bulky and/or expensive accessories. Chromatographic separation with back flush technology ensures extraordinary reliability and stability on stationary analyzers.

COMPARISON WITH SIMILAR EQUIPMENTS TRADITIONAL FID ANALYZER VENUS 301 FID  Frequent calibration and maintenance.  Reduced calibration and maintenance costs due to Span& zero drifts costs thanks to our loop sampling system (capillary sampling clogging effect). technology.  Limited diagnostics and interface.  Developed diagnostics and interface, thanks to our PC embedded techno

REQUIREMENTS Our FID systems requires hydrogen and compressed air Air from your network (3 bar) Hydrogen 4,5 grade pure (3 bar) 40 Liters gas cylinder or optional H2 generator CONSUMPTION = 50 ml/min. Nira filtering system CONSUMPTION = 1 m³/hour

CALIBRATION AND MAINTENANCE We worked hard to minimize maintenance and calibration frequencies, obtaining record results. Every 6 months: Calibration check, the procedure is guided from the software and takes just few minutes using a preinstalled standard gas cylinder. Once a year, ask for a service visit from our staff.
