Particle handling

Our high-temperature combustion devices multi N/C 2300 and multi N/C 3300 are unbeatable when it comes to analyzing particle-rich samples. This is due to their unique injection and rinsing techniques. These prevent sample carryover and increase the service life of your device

The multi N/C 2300 injects the sample directly into the furnace from the microliter syringe. The entire sample, including all particles, is transferred as the syringe is emptied from top to bottom. In addition, the syringe is effectively rinsed and thermally cleaned from the outside, eliminating any chance of sample carry-over.

With the multi N/C 3300, the sample is drawn up into a large-diameter sample loop instead of a syringe. From this, it is completely injected into the furnace, including all particles. The injection system is then effectively rinsed - also by backwashing into the waste container of the autosampler.     

BOD5 / COD - TOC Parameter Conversion

Do you use the parameters biological (BOD5) and chemical oxygen demand (COD) to monitor the organic pollution of water? Did you know that measuring the parameter TOC and then converting it into COD and BOD5  offers you numerous advantages? The measurement of total carbon is not only more precise and considerably faster. With multi N/C x300 devices it can be done without hazardous reagents or costly test kits. The conversion from TOC to BOD5 and COD is done automatically by the multiWin pro software.

Salt Kit

With the multi N/C 3300, we offer a salt kit for analyzing TOC in highly saline samples, for example in brine, seawater, or cathode materials for lithium-ion batteries. With the salt kit, you can extend the service life of consumables and thus significantly reduce maintenance work and running costs.

The salt trap collects salt that remains after sample evaporation, thus preventing these deposits from causing rapid wear of the catalyst and the combustion tube as well as preventing blockages in the carrier gas flow. The salt kit thereby ensures the accuracy and precision of the measurement results for a significantly higher number of samples. Thus, maintenance intervals are extended.
