rapid N cube
The compact power in protein analysis
Nitrogen/protein analyzer according to Dumas for routine analysis of samples such as food or animal feed up to 1 g sample weight. The rapid N cube is a fast, safe and environment-friendly alternative to the classical Kjeldahl method. The rapid N cube is a particularly reliable and durable instrument based on the most modern microelectronics and mechanics.
Modes
The rapid N cube is optimized for nitrogen analysis. Optionally the rapid N cube can be equipped with IR detector for the detection of sulfur.
Continuous flow-Hybrid technology
Optionally the rapid N cube can be equipped with the active CF-Hybrid technology. In this mode without any moving parts only a fraction of the combustion gases is lead to the detector. In contrast to already existing discontinuous gas splitting devices the use of failure prone tanks is prevented. If needed, the system can be switched to standard mode within minutes to reach perfect detection limits.
Specifications
High temperature combustion
Dumas combustion method for N-Protein acc. to AOAC, DIN/ISO, EN and many international standards
Large weighing range
Up to 1 g sample weight (1g organic matter)
Concentration range
from ppm to 100% or 500 mg N abs.
Clean, safe, fast
The analysis only takes a few minutes, no aggressive or toxic chemicals are used, CO2 as intelligent carrier gas
Easy installation requirements
48 x 55 cm benchtop space, 1 power supply (230, 110, 100 V), and two gases are sufficient for maintenance free long time operation
Multipoint calibration
stable over months and matrix independent
Instrument control
with a standard PC for perfect results also for unknown or heavily variable sample matrices, 21 CFR Part 11 functionality available. Possibility for remote service due to full digitalization of the instrument electronics
Options
Electronic analytical balance:
balance and elemental analyzer form a system. We offer micro balances and analytical balances from the leading manufacturers with our instruments.
Sample feeder:
alternative carousels are available for larger samples with up to 120 samples with reduced volume.
Capsule press:
for the dosing and gas tight sealing of tin capsules for liquid and sensitive samples. Contains consumables for approx. 500 samples.
vario Liquid Sampler, VLS:
The VLS automated sample feeder is used for liquid injections directly into the combustion chamber.
Continuous flow Hybrid option:
the CF-Hybrid serves for an optimized lifetime of four consumables.
Manual gas/liquid injection:
for the injection of liquid or gaseous samples via a septum free injector port and a micro-syringe.
Sample former with pressing tool:
for the compaction of the wrapped samples and removal of air in soil samples.
Manual pressing tool:
for the manual compaction of the wrapped sample.
Consumables
Our kits of consumables contain all necessary parts and chemicals for the corresponding mode. Under more it contains combustion/reduction tubes, all chemicals and instrument specific wear parts. We do not compromise on quality of the used parts and chemicals – this is the prerequisite of a guaranteed long lifetime of our instruments.
Kits of consumables for approx. 4000/2000/1000 analysis
Kit with small wear parts: useful combination of the most important O-rings and fuses for the laboratory.
Of course all the consumables can also be ordered separately, please ask for our brochure!
