Introduction
An elemental CHN analyzer is an analytical instrument used to determine the carbon, the hydrogen, and the nitrogen content of the organic and the inorganic materials, and it is used in the chemistry, the agriculture, the environmental, the materials, and the many other applications. The elemental CHN analyzer measures the carbon, the hydrogen, and the nitrogen by the combustion of the sample in the oxygen, in which the carbon is converted to the carbon dioxide, the hydrogen to the water, and the nitrogen to the nitrogen oxides or the nitrogen gas, and the combustion products are separated and detected by the thermal conductivity or the infrared detectors, and the elemental composition is calculated; the elemental CHN analyzer consists of a combustion furnace, an oxygen and a carrier gas system, a separation column, a detection system, and a control and a data analysis system, and it provides the percentages of the carbon, the hydrogen, and the nitrogen, with features such as the automated operation and the data management; the elemental CHN analyzer is used for the analysis of the organic compounds, for the analysis of the soils and the fertilizers, for the analysis of the fuels, for the analysis of the polymers and the materials, for the research, and for many other applications, and it is an essential instrument for the elemental analysis. Elemental CHN analyzers are used in the chemistry laboratories, in the agricultural laboratories, in the environmental laboratories, in the research, and for many other applications. With their combustion, elemental CHN analyzers are essential for the elemental analysis.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The CHN elemental analyzer is used in organic chemistry, pharmaceutical, environmental, agricultural and material laboratories for simultaneous determination of carbon, hydrogen and nitrogen content in solid and liquid samples. It supports organic compound characterization, pharmaceutical raw material verification, soil and plant nutrient analysis, coal and fuel quality testing, and polymer composition analysis. The simultaneous CHN measurement provides elemental composition data for formula verification, purity assessment and material characterization, making it essential for research and quality control in organic and analytical chemistry laboratories.
Q2: What standards does the instrument comply with?
A: The instrument supports analytical methods referenced in ISO 10694 for soil organic carbon, ISO 13878 for soil total nitrogen, ASTM D5373 for coal CHN analysis, and relevant GB/T standards for elemental analysis. The hardware complies with IEC 61010 laboratory safety standards. Calibration should use certified reference materials traceable to international standards.
Q3: What is the warranty period for the whole machine and key components?
A: The whole analyzer is covered by a 12-month warranty. The combustion tube, detector, gas system and controller are covered, while reagents, combustion tubes and filters are consumables excluded from warranty. Damage from improper sample introduction or corrosive gas erosion is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained analysts familiar with elemental analysis principles and sample preparation. We provide structured training, operation manuals and application support. Routine sample analysis can be performed by trained operators with software guidance after initial setup and calibration.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Calibration with certified CHN reference standards should be performed before each analytical batch and after reagent or tube replacement. Drift verification with a check standard is recommended during long sequences. Full system maintenance and calibration are recommended every 6-12 months.
Q7: Are supporting consumables universal?
A: Reagents, combustion tubes and filters are available from multiple qualified suppliers, though original consumables are recommended for optimal performance. Calibration standards should be sourced from accredited providers. Long-term consumable cost is moderate and depends on sample throughput.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes autosampler capacity, gas configuration and detector options. Additional accessories such as spare tubes and reagent sets can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the analyzer, autosampler and accessories with an operation manual. Remote commissioning guidance is provided. On-site installation and training are not included for standard orders but can be arranged for laboratory setup projects.
Q10: What types of samples are compatible with this equipment?
A: The analyzer analyzes organic solid and liquid samples within the element concentration range. Samples containing high halogen, sulfur or phosphorus content may require special reagents or catalyst selection to avoid interference. Inorganic samples with high carbonate content may affect carbon results and require acid pretreatment. Users should verify sample compatibility and required pretreatment for each matrix type.
