multi N/C®- series – the right analyzer for every application
|
|
The multi N/C® series is the powerful family of instruments with a convincing overall concept for the fully automatic and simultaneous analysis of total carbon and total nitrogen TN from every sample. |
The compact power pack!
The multi N/C® 2100 is the space-saving TOC/TNb analyzer which demonstrates its strength particularly in the field of environmental analysis. Along with VITA®, the FR NDIR-Detector and catalytic hightemperature
combustion up to 950°C, multi N/C® 2100 is equipped with a perfect injection technique for particlecontaining
samples.
The integrated autosampler and the solid technique turn it into a compact routine analyzer.
Versatility at the highest level!
No matter whether ultra-pure water or waste water, multi N/C® 3100 is suitable for all samples. This is made
possible by the combination of catalytic high-temperature combustion, VITA®, the Focus Radiation NDIR-Detector, as well as flow injection with intelligent rinsing technology for particle-containing samples.
In addition, multi N/C® 3100 is particularly fast and thus permits high sample throughputs.
TOC-determination made easy!
The maintenance requirements of wet chemical TOC analyzers are very low. The multi N/C® UV HS is a system which works both with an oxidation agent (peroxodisulfate) and a highly effective UV radiation source for sample oxidation. At the same time the system is highly sensitive and suitable — along with ultra-pure water samples — also for drinking water or special samples, such as acids, electrolysis baths and other aggressive matrices.
Unlike classical TOC analyzers with an UV reactor, multi N/C® UV HS uses two wavelengths instead of just one: 254 nm and 185 nm. The hard radiation obtained in this way guarantees a complete oxidation of even the most stable carbon compounds. The effective blank value reduction by means of automated purging of the reagents ensures minimal system blank values. For ultra-pure water analyses, a decisive advantage
can be to work only with UV radiation, without oxidation agents, because the blank value of the oxidation agent can cause interference in the trace analysis. This is not a problem with multi N/C® UV HS! A suitable method can be selected in the user interface, so that the High Power UV reactor delivers the necessary energy for complete oxidation.
Designed for the pharmaceutical industry!
Pharmaceutical applications require special technological solutions: highest sensitivity and precision as well as adaptation to the requirements of the pharmaceutical industry.
multi N/C® pharma has been designed especially for pharmaceutical applications. Two models are available: multi N/C® pharma HT and multi N/C® pharma UV.
Depending on the application, two digestion principles are available: catalytic high-temperature combustion up to 950°C (multi N/C® pharma HT) or wet chemical oxidation in a High Power UV reactor (multi N/C® pharma UV). At the same time, the focus is on the precision and correctness of the measurement results in the lower measurement range. This is possible thanks to the VITA® Flow Management System and by high sample injection volumes with the help of a high-precision injection syringe. And also by the use of a volume-specific calibration method which can be used to perform reliable calibration down to the lower ppb range.
Minimal system blank values are obtained through the automatic purging of the used chemicals. In addition, a blank value free digestion without reagents is available. multi N/C® pharma is thus uniquely suitable for ultra-pure water analyses, in particular for the analysis of WFI (water for injection purposes), AP (purified water), liquid or solid samples (swabs) from the cleaning validation and other typical applications in the pharmaceutical labs.
