Metrohm USA has announced the launch of the new ProfilerF series of Total Fluorine Analyzers. The ProfilerF Wastewater system is a single analyzer system capable of measuring the total organic fluorine profile in liquid samples and, with it, the impact of potentially harmful compounds on the environment. The ProfilerF Solids analyzer accurately measures the fluorine content of solid samples with dramatically improved accuracy and reproducibility compared to current methodologies.

The ProfilerF Wastewater analyzer is a new and unique analytical tool that simultaneously quantifies the total fluorine and free fluoride present in wastewater. Incorporating combustion technology, this new analyzer determines the covalently-bound organic fluorine in the presence of a 25-fold higher free fluorine background.

The ProfilerF Solids analyzer determines the total fluorine concentration in solid samples with greater sensitivity and accuracy compared to other analytical techniques. The analysis of fluorine content in solid samples is important in a variety of industries and applications for quality control, environmental monitoring and remediation, and provides insight and efficiency for manufacturing processes. For example, the concentration of Polymer Processing Additives, or PPA, is critical when preparing polymer masterbatches and to ensure final product quality.

“For wastewater samples, total organic fluorine concentration is the next level of non-targeted methods for environmental monitoring. The ProfilerF Wastewater analyzer helps facilitate compliance with fluorine discharge levels to protect the environment,” says Edward Colihan, President and CEO of Metrohm USA. “Measuring total fluorine in solids will give those working in a variety of industries the benefit of higher yields, consistency monitoring and lower production costs.”

With the ProfilerF, results are more accurate, definitive and simpler to obtain, helping ensure process and environmental compliance.

Combustion Ion Chromatography – automated determination of halogens and sulfur in solid and liquid samples

Metrohm AG

Metrohm presents Combustion IC (CIC), a fully automated system for the simultaneous determination of halogens and sulfur in widely differing matrices. With CIC, unlike with alternative methods the concentrations of the different halogens can each be shown separately. Moreover, digestion by pyrolysis is superior to offline digestion methods with regard to sample throughput and precision and correctness of results. CIC is ideal for routine analysis in a variety of fields, as it neither prior knowledge about the sample matrix nor complicated method development are required. CIC is recommended for quality control of raw materials, intermediates and finished products, and is also suitable for straightforward monitoring of compliance with the relevant laws and standards in the environmental field (e.g. DIN EN 228, IEC 60502-1, RoHS, WEEE, ...). Thus, CIC enables determination of halogens and sulfur in all kinds of fuels, lubricants, additives and other petroleum products, as well as in polymers, flame retardants, textiles, special chemicals, catalysts and all kinds of waste. The new CIC system consists of a Combustion Module from Analytik Jena and an absorption and IC part from Metrohm. Sample digestion is controlled automatically by a flame sensor. The flame sensor measures the light from the pyrolysis oven and controls the feed rate of the sample boat into the oven in proportion to the intensity of the light emitted during combustion. Thus, duration of the combustion is optimized so that combustion of the sample is always complete (soot prevention), while time consuming delays of throughput are avoided. Thanks to the automated control of the sample digestion, method development for combustion is no longer needed; both different matrices and different sample quantities can be treated using the same, universal «method». The complete system, including sample delivery, sample digestion and analysis, is controlled by MagIC Net™, the proven software for ion chromatography.
