Taking care of it – a service visit with the Elementar Service Technician Guillaume Tallepied

written by Marc Ruppenthal


When a CHNS combustion analyzer is in need of a service visit, the call for action is usually not related to a dramatic technical emergency. In most of the cases a service visit can be regarded as similar to a recurring routine inspection of a car: The analyzer is found in good condition and just needs some care for the months and years ahead.

The service visit of Guillaume Tallepied, Service Technician at Elementar France, at the Institute of Chemistry of Natural Substances (ICSN, Institut de Chimie des Substances Naturelles) in Gif-sur-Yvette, France, on last Tuesday fell in this category of routine inspection. The ICSN research institute, which is organized under the roof of the National Center for Scientific Research (CNRS, Centre National de la Recherche Scientifique), investigates the chemistry of natural substances with respect to their potential use in medicine and pharmacy. The ICSN operates two vario MICRO cube system from Elementar – one in CHNS mode and one in O mode.

At the customer site, Guillaume did a routine inspection of the analyzer and a yearly cleaning of the ball valve. The ball valve – a patented piece of Elementar technology – ensures that samples are transferred to the combustion furnace free of ambient air. This is important because atmospheric gases (especially nitrogen and oxygen) would otherwise produce unwanted blank values in the measurement.  When the cleaning of the ball valve was finished, the automated leak check started through the software confirmed that the system was ready for analysis, and the first measurements were started.

“Just a routine mission. Everything is fine.”

was Guillaume Tallepied’s conclusion when he inspected the results. The two instruments – one of them already eleven years old – will remain in good condition without any sign of malfunction – a manifestation of not only the quality of the analyzer, but also of the quality of the service.
