The analysis of Carbon and Nitrogen is important in soil, plant, animal feed, food samples, sediments and sludge samples. The Skalar PrimacsSNC Analyzer combines the analysis of Total Carbon and Total Nitrogen in one unit using high temperature catalytic combustion.
The samples are introduced into the high temperature combustion oven by the unique vertical â€œbottom-to-topâ€ sample introduction system. At 1050Â°C the carbon is completely oxidized to CO2 in the presence of a catalyst. The CO2 is measured by Non Dispersive Infra Red Detection (NDIR) for Total Carbon. The analysis of Nitrogen is based upon the well-proven DUMAS technology. Nitrogen is converted in NxOy which is reduced at 600 Â°C to N2. The N2 gas is measured by Thermal Conductivity Detection (TCD). The software displays the carbon and nitrogen peaks simultaneously in real-time and the results can easily be printed or exported to a LIMS system.
Whenever priority samples have to be analyzed, the work list can be extended during the run. The sample is weighed into a re-usable quartz crucible and the sample weight is automatically transferred to the work list in the software, which avoids transcription errors.
The PrimacsSNC Analyzer provides an accurate and reliable solution for the automation of Total Carbon and Total Nitrogen analysis and has been designed as an easy-to-use and low maintenance analyzer. Due to the unique vertical â€œbottom-to-topâ€ sample introduction the sample ashes remain in the crucible after analysis and are taken out of the instrument with the removal of the crucible. This avoids sample ash build-up in the combustion zone and therefore reduces the maintenance requirements of the instrument. The re-usable crucibles and the low consumption of combustion and carrier gas result in a low cost-per-test.
The PrimacsSNC complies with international regulations such as CEN, ISO 10694 and NEN-EN 131137, AOAC 990.03, AOAC 992.15, AACC 46-30, ASBC and many more.
