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.
