CN 802 Carbon Nitrogen Elemental Analyzer

A nitrogen analyzer measures the concentration of nitrogen or nitrogen-containing compounds in gas streams, liquids, or solids. It is used in environmental monitoring, combustion analysis, agricultural soil testing, food and beverage quality control, and pharmaceutical manufacturing. Calibration with high-purity, NIST-traceable nitrogen calibration gas ensures measurement accuracy and regulatory compliance.

Carbon nitrogen elemental analyzers typically require high-purity carrier gases such as helium or nitrogen, as well as reference calibration standards containing CO₂ and N₂ or NOx at known concentrations. NIST-traceable certified gas mixtures are essential to verify instrument linearity, zero points, and span accuracy across the full measurement range.

NIST traceability means a calibration gas's certified composition is referenced back to national measurement standards maintained by the National Institute of Standards and Technology. This ensures your analytical results are comparable, defensible, and compliant with regulatory requirements. SpecGas Inc. produces all blends with NIST-traceable standards using gravimetric blending and verified analytical techniques.

Yes. SpecGas Inc. specializes in custom specialty gas blending to exact customer specifications. Whether you need a specific PPB-level concentration, a multi-component mixture, or an unusual reactive gas blend, SpecGas can accommodate your requirements with adaptable tolerances and fast in-house turnaround.

SpecGas Inc. offers calibration gases in a wide range of cylinder sizes from 17 liters to 2000 liters gas phase volume. Cylinder options include disposable steel and aluminum, refillable high-pressure aluminum and steel, and nickel-plated cylinders for corrosive or reactive gases. Disposable cylinders are ideal for field applications and international shipping.

Stability depends on the gas composition and cylinder treatment. SpecGas Inc.'s proprietary internal cylinder treatment process is specifically engineered to extend the shelf life of reactive gas mixtures, including toxic, corrosive, and low-PPM blends. All mixtures come with the SpecGas Stability Guarantee — if a mixture is disputed, SpecGas will immediately remake and reship a replacement at no charge.
