Determining Nitrogen Traces, as Sensitive as Never Before
Mar 03 2017
Contrary to sulfur – a parameter with legally defined limit values - the nitrogen content is not strictly regulated for petrochemical materials. Nevertheless, nitrogen plays an important role when it comes to the performance of catalysts and thus the quality of the end products, for example in refineries, the polymer industry or solvent production. Therefore, a strict control (e.g., ASTM D 7184) of the raw materials used is necessary.
In the polymer industry, high purity, gaseous or liquid monomers such as propylene or cresol are used as precursors for the polymerization. In order to ensure an optimum reaction, limits <100 ppb N are required. Only chemoluminescence detectors with integrated high-performance vacuum systems are capable of meeting these challenges. Thanks to the HiPerSens® detection and an efficient drying of the measurement gas, the compEAct allows fast and reliable determination of nitrogen contents even in ultra-trace range.
In contrast to conventional systems, the compEAct requires only small sample volumes and a minimum of repeat measurements for the nitrogen determination even in the lower ppb range. This ensures high sample throughput also for demanding applications. Indispensable features for quality assurance and automatic control of permitted N-limits facilitate the validation of the measurement results.
