The Dumas method of N/Protein determination utilizes metals such as tungsten or copper which are converted to their metal oxide form as part of the process. This is a major cost associated to the cost-per-analysis of this method and requires frequent exchange of the metals for fresh reagents.
Elementar have developed a unique method whereby the metal oxide formed by reduction of Nitrogen is regenerated back into the active metal species enabling it be used again. This EAS REGAINER® method has enabled a reduction in the cost-per-analysis of up to 50% and increases reagent lifetime by approximately five times. This is achieved with no reduction in the method performance which still outperforms the requirements of internal standards for Dumas N/Protein analysis.
Two dedicated instruments for N/Protein analysis utilise the EAS REGAINER® method catering for differing customer requirements. For more information on the method performance and cost-per-analysis download the application note “Long-term accuracy of N/protein analysis utilizing the EAS REGAINER® technology” below.
