NSX-5000

The NSX-5000 determines sulphur, nitrogen and chlorine.

Nitrogen and chlorine, for example, are catalyst poisons and can be measured to determine the service life of a catalytic converter. Sulphur, on the other hand, is an exhaust gas in the fuel that is measured by fuel generators, for example. With the addition of a combustion IC, the halogens fluorine, bromine and iodine, which are corrosive and attack metals, can also be determined. However, there are many other applications.

Examples of applications with the NSX-5000 are

• Determination of S, N, Cl in petrochemical raw materials, intermediate and end products
• Sulfur determination in biofuels / FAME
• Determination of S, N, Cl in solvents
• Measurement of S, N, Cl in solid samples
• Trace and ultra-trace determination of sulphur and nitrogen in fuels, gases and liquefied gases
• Nitrogen content determination in pharmaceutical raw materials, intermediates and end products
• Measurement of nitrogen in water and wastewater samples
• Determination of nitrogen in agricultural products (starch, sugar, etc.)
• Determination of sulphur and nitrogen in edible oil and animal fats
• Measurement of AOX, EOX, POX, AOF, EOF in water, wastewater, soil and sewage sludge
• Determination of sulphur content in hydrogen
• Determination of total chlorine in coal
• Determination of total chlorine in palm oil

The NSX-500 is suitable, for example, for companies that need to comply with or monitor certain limit values. In the case of sulphur, nitrogen or chlorine, for example, this applies to refineries, the petrochemical industry, the chemical industry and environmental laboratories.

Yes, with the addition of a combustion IC, the NSX-5000 can also measure fluorine, bromine and iodine.

Yes, the environmental parameters AOX, EOX and POX can be measured with the chlorine module.

The NSX-5000 carries out the measurement in 4 steps. First the sample is loaded (manually, semi-automatically or fully automatically), then the sample is burned. This is followed by gas processing and finally detection by means of potentiometric titration (Cl, S), chemiluminescence (N), UV fluorescence (S) and/or ion chromatography (F, Cl, Br, I, S).

With the NSX-5000, you have the option of putting your system together in a modular way. The two oven options offer different advantages. With the vertical oven, samples are loaded vertically and large sample volumes can be processed efficiently and very reproducibly. The horizontal oven, on the other hand, offers maximum flexibility in terms of sample types.

Yes, the NSX-5000 is controlled by a dedicated control software that enables intuitive use for simple and robust operation.

• SD-500: The sulphur detector enables high-precision measurements down to 5ppb (LOQ).
• ND-500: The nitrogen detector offers very good precision and linearity even in the lowest measuring range.
• MCD-500: The high-precision microcoulometer enables the determination of chlorine contents down to 50 ppb (LOQ).
• GA-500: The absorption module enables the collection of combustion gases. F, Cl, Br, I and S can be collected quantitatively and automatically transferred to an ion chromatography system for further measurement (combustion-IC). The NSX-5000 is the only sulphur-nitrogen measuring system that can also be used as a c-IC.

There are up to 120 positions for tubes (2ml, 4ml, 6ml) and up to 49 positions for boats (ceramic)

The NSX-5000 has the following measuring ranges:

Chlorine: 0.05-50 µg (Cl)

Sulphur: 0.005-20,000 mg/Kg

Nitrogen: 0.01-5,000 mg/Kg

C-IC: 0.05 mg/Kg – 100%

The analysis time varies between 3 and 20 minutes depending on the parameter and matrix.

The NSX-5000 works with 99.7% oxygen or 99.98% argon.

Of course, we will be happy to come to you and show you the appliance so that you can get to know the technology.

Once your NSX-5000 has been installed, our service team will be available to provide you with detailed product training. Most questions will arise as you work, so we will also be able to help you with any questions that arise at a later date – at your premises or flexibly via an online meeting.
