Instrument Introduction

The KR-ONH6700 oxygen nitrogen hydrogen analyzer is a new generation element analysis instrument. It features a desktop integrated design, beautiful appearance, and easy operation.

The oxygen nitrogen hydrogen analyzer is an intelligent analytical instrument composed of a pulse furnace and a computer, with a pyroelectric sensor and a high-precision thermal conductivity detector as the core. The instrument is mainly used for the analysis of oxygen, nitrogen, and hydrogen content in ferrous metals, non-ferrous metals, rare earth metals, inorganic substances, ores, ceramics, and other materials in industries such as metallurgy, machinery, commodity inspection, scientific research, and chemical engineering.

Instrument principle

Oxygen, nitrogen, and hydrogen in metal and non-metallic solid materials are detected using the inert gas melting principle. In the determination of oxygen, nitrogen, and hydrogen, the weighed sample is placed in a graphite crucible and melted through high-temperature heating in a helium (argon gas can be used for single oxygen measurement) airflow. The oxygen in the sample reacts with the carbon in the graphite crucible to generate carbon monoxide (CO), and the nitrogen in the sample escapes in the form of nitrogen. These mixed gases are sent to the conversion furnace by helium gas, and carbon monoxide (CO) is converted into carbon dioxide (CO2). The nitrogen does not react. The mixed gas after passing through the conversion furnace is sent to an infrared detection cell, where carbon dioxide (CO2) (H2O) is detected. Then, after infrared detection, the carbon dioxide (CO2) and water in the mixed gas are adsorbed, and the remaining nitrogen and helium gas mixture is detected through a thermal conductivity detection cell. Quickly and accurately determine the oxygen, nitrogen, and hydrogen content in steel, cast iron, alloys, copper, zirconium, titanium, rare earth materials, and other inorganic substances.

Motor: The modulation system adopts a high-precision stepper motor controlled by a microcontroller, achieving long-term stability of the modulation frequency;

Light source: The infrared light source uses efficient and long-lived precious metal miniature infrared luminescent bodies and gold-plated metal mirrors;

Constant temperature: The entire gas chamber is controlled at a constant temperature to ensure the constant temperature of the analysis gas and measurement accuracy. A temperature compensated semiconductor detector is used to ensure that the instrument is minimally affected by external factors and the baseline is very stable.

High precision detection system

The use of a highly sensitive thermal conductivity detection cell, continuously adjustable pool current, high-precision amplifier, and 24-bit A/D sampling card hardware ensure the determination of nitrogen content from ultra-low to large ranges.
