Analyser N/protein RapidN cube

Fast N/Protein Analyzer rapid N cube

Analyzer for fast and absolutely safe measurement of nitrogen or protein according to the Dumas combustion method with samples up to 1 g  or 1 ml of liquid samples (with option capsule sealing press). Due to the latest micro-electronics and mechanics the rapid N cube is the most compact high performance elemental analyzer for real organic macro samples with a measuring range of up to 200 mg N absolute.

• Analysis time from sample to sample is approx. 4 minutes.
• Automatic sampler for 60 samples up to approx. 1 g or optional 120 samples for up to approx. 300 mg weight in one integrated magazine. Samples can be further added at any time during operation.
• Blank free sample injection by means of the reliable ball valve. Long, trouble-free operation due to magnetically operated safety shield between ball valve and combustion zone. Combustion at approx. 960°C in a robust stainless steel tube. An oxygen concentration of 100% is reached by jet injection directly at the sample. This results in an oxygen  saving of 95% compared to other analyzers.
• The combustion gases are transferred to a second furnace for catalytic post oxidation. This ensures that even high concentrations of organic components are completely oxidized. The reduction of the nitric oxides to N₂ takes place in a third furnace. The patented use of tungsten instead of copper increases the capacity by a factor of 3.
• An effective multiple-stage drying allows the measurements of even 1 ml liquid samples.
• Subsequently, the formed nitrogen is measured with a wide range thermistor TCD which is destruction proof against oxygen. There is no need for CO₂ removal due to the efficient use of CO₂ as carrier gas.
• In connection with an electronic mass flow controller directly before the detector an excellent long time stability can be reached. The furnished instrument calibration can be used for months or even years.
• The measurement of the complete gas stream allows the online monitoring of the combustion process and automatic decrease of the analysis time and oxygen demand.
• Modern electronics and instrument software under Windows® XP professional, Vista business or 2000 for the user friendly operation and data evaluation of the analyzer (English or German) via a connected PC.
• Integrated user maintenance software with automatic leak test, wake-up/sleep function, direct data export into Excel® and connection to LIMS and other data networks.
• All operation functions and checks incl. gas flows and pressures are digitally controlled and/or readout capable. Thus a remote diagnosis and operation via the internet is possible.
• Easy to maintain and cost efficient long term operation. High safety standard, e.g. by low voltage in the entire instrument incl. furnaces.
• 10 years furnace guarantee.
