Determining the Carbon, Hydrogen, Nitrogen, Oxygen, and Sulfur content of unknowns is one of the most basic and essential needs for any chemist.
You can increase productivity and maximize confidence in your CHN/O/S results with the CE 440 Elemental Analyzer.
The CE 440 is designed to give you accurate and reliable results, regardless of sample type.
The CE 440 uses thermal conductivity detection for measuring carbon, hydrogen, and nitrogen, after combustion and reduction. This time-proven technique allows measurements to be made over a very wide range of concentrations.
Only the CE 440 offers you all these advantages:
Accuracy and Precision - The CE440 provides analytical data of unsurpassed accuracy and precision. The complete control of combustion parameters combined with steady state measurement of combustion products ensures a level of accuracy and precision that cannot be matched. Sample Data
Versatility - With its unique combination of both static and dynamic combustion, the CE 440 can combust the widest range of sample types of any CHN/O/S instrument. Our unique horizontal furnace allows for automatic removal of the residue from each sample after analysis, avoiding memory effects and gas flow problems, which can occur with vertical furnace systems.
Reliability - The CE440 is a fully automated CHN/O/S elemental analyzer. The system with its Window® based P.C. operating software has been designed to reduce human error through incorporation of extensive automation, customer help, and diagnostic facilities. Using the technique of steady-state measurement of combustion products, the CE 440 is inherently more reliable than gas chromatographic systems which are dependent on flow, column temperature, and dead volume management.
With the lowest operating cost of any elemental analyzer available, the CE 440 won't strain your budget. Low gas and reagent consumption combined with higher reduction tube life make it the most economical CHN/O/S elemental analyzer to operate.
Continuous diagnostics and automatic maintenance alerts make operation almost fool-proof. By monitoring signals, voltages, and sample throughput, the instrument provides you with continuous status reports on consumable reagents as well as an immediate warning should a problem occur. And, most parts are user-replaceable, further reducing cost and downtime.
