High salt concentrations. No problem with the QuickTONultra.

This online TNb analyzer can handle salt concentrations up to even 300 g/l sodium chloride (NaCl). Salts that melt at the temperature of 1,200°C are vaporised by the combustion power and carried out with the carrier gas to settle in a special retrieving device.

The QuickTONultra. Ultra quick measurements and maintenance.

The QuickTONultra is designed to operate in a batch mode. The TNb measurement takes place in within 1 – 2 minutes. This speed guarantees that very short peaks can be determined very well during a daily cycle.

The analyzer’s availability is over 98%. The weekly service is about 30 minutes.

The detection. You have the choice.

The chemiluminescence method (CLD) is wellknown and proved. Its disadvantages, however, lay in its high cost of investment, consumables as well as its high maintenance efforts.

With regards to the economic efficiency the innovative electro-chemical detection (ECD) is a good alternative. The measurement cell is less expensive in purchase and needs only minimal maintenance since the requirements for the carrier gas are significantly lower. Nevertheless, it offers the most comparable measurement accuracy.
