Elemental Analyzer

Fast and simultaneous Carbon Nitrogen analyses The CN 802 is a robust and flexible combustion analyzer, that works following official reference methods for the determination of carbon and nitrogen in many industrial sectors such as agriculture, environmental, food feed, and chemical. The proprietary CNSoftTM software powers the CN 802 and produces unsupervised, simultaneous results in 5 minutes of: TC: Total Carbon TOC, TIC: Total Organic and Inorganic Carbon (after acidification) TN: Total Nitrogen C/N Ratio The CN 802 is a safe analyzer that does not require aggressive chemicals or time-consuming analysis steps. Just prepare your sample and walk away! Sensitivity and Versatility at its best The CN 802 enables analysis across a wide range of sample types, including solid, semi-solid, and liquid samples. It accommodates large weights and volumes, and it is suitable both for inhomogeneous samples and those with low concentration levels. The CN 802 ensures high-precision results and excellent reproducibility with: A carbon limit of detection ranging from very few ppm to 150 mgC; The lowest LOD for Nitrogen; A relative standard deviation (RSD) lower than 0.5% (EDTA). Capable of processing up to 117 samples at a time, the VELP C/N elemental analyzer boasts exceptional efficiency, enabling the highest sample throughput. This is made possible by the electronic autosampler and balance connection to the PC for direct weighing data transfer. Laboratories have the option to select between Helium and Argon as the carrier gas. Additionally, with dedicated accessories, kits, and tin cups, you can easily analyze liquid samples with high sensitivity and accuracy. Efficiency for your lab CN 802 analyzes samples of up to 1 g, effectively reducing the cost-per-analysis through VELP combustion technology and the use of genuine consumables with extended lifetimes. The maintenance-free, non-dispersive HighSensIRTM detector ensures consistent performance over time for the analysis of high and low carbon content samples; The CN 802 LoGasTM TCD works with no reference gas ensuring the lowest gas consumption on the market; The possibility to seamlessly switch to argon prevents helium availability issues; Optimized combustion leads to very low oxygen consumption: when utilizing a pre-installed method, the instrument accurately doses the gas to ensure full sample combustion based on its weight and matrix, saving resources; The DriStepTM physical water trap not only requires no maintenance but also removes 99% of water without the need for chemicals; The installation of the CN 802 is straightforward, and its compact design saves valuable bench space in your lab. The combustion technology drastically improves productivity and eliminates the use of chemicals compared to wet chemistry N/protein determination methods.

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. CE440 Features Rapid analysis for high productivity - analysis time of less than 5 minutes per sample. Unique combustion technique makes it possible to analyze any sample type, from volatiles to refractories. Stable thermal conductivity detector provides linear response with superior precision and accuracy.Windows software with data storage for statistical analysis and flexible report generation. Horizontal sample injection removes interfering residue between each sample run. Continuous diagnostics with automatic maintenance alerts. Low reagent consumption - industry's lowest cost per sample. Applications With its wide linear range, combined static/dynamic combustion and unique horizontal furnace design allowing for the removal of sample residue between runs, the CE 440 is capable of analyzing the widest range of sample types - quickly, easily, and reliably. Typical applications include: Organics and Pharmaceuticals - The CE 440 can analyze virtually any class of organics, including organometallics, heterocyclic nitrogen derivatives, steroids, polynuclear aromatics, and organophosphorous. Environmental - Analyze the effects of fuels, oils, and their by-products on the environment, or study the composition of material retained by membranes used in oceanography, water filtration, and air monitoring. Polymers - The CE 440 provides a fast, direct method for determining elemental composition of polymers, copolymers, and blends. Even samples with high levels of halogens, like PVC or Teflon , can be analyzed rapidly and accurately. Refractories - Nitrides, graphite fibers, and ceramics are easily analyzed - even carbides with melting points over 2000 C. Volatile/Air Sensitive Samples - Volatile and air sensitive materials are easily analyzed using our capsule sealing device. Other Application Areas: Plastics, petrochemicals, agriculture, food, and pyrotechnical compounds.
