Infrared hydrocarbon analyzer

Key Features:

①High reliability and good safety

The weight method for measuring carbon and hydrogen is one of the most difficult tasks in coal quality analysis. Its testing components are scattered and there are many chemical reactions, so it is greatly affected by human factors. It requires high operational skills from the testing personnel, and the testing components are also prone to malfunction, resulting in low reliability of the natural testing results. The Coulomb method for measuring hydrogen has improved the level of automation, but its electrolytic cell is prone to contamination and damage, making it difficult to test. The reliability of the instrument is also low, while the infrared method for measuring hydrogen is a physical method that burns carbon and hydrogen elements to formCO2Send gaseous water into an infrared gas sensor and scan it with characteristic infrared spectraCO2The degree of intensity reduction in characteristic infrared spectra of gaseous water and gasCO2Proportional to the concentration of gaseous water and gas, the degree of intensity reduction in the characteristic infrared spectrum can be determined by detecting the intensityCO2By integrating the concentration with the water vapor concentration, the total amount of hydrocarbons can be determined. The analysis process after sample combustion does not involve chemical reactions, thus greatly improving the reliability of the entire instrument and reducing the failure rate. No need to prepare chemical reagents, safer work.

②High accuracy and good stability

The characteristic of infrared spectroscopy is that the light in the infrared spectrum is onlyCO2It has an absorption effect on gaseous water, which means that the characteristic infrared spectrum only sensesCO2andH2OGas, the testing process is not affected by other gases, there are no chemical reactions, the stability is good, and the measurement results are accurate and reliable. The scope of analysis is broad. In order to prevent moisture from entering the air and affecting the testing, an automatic continuous injection, pneumatic automatic sealing, and high-purity gas automatic blowing device were designed to ensure that it is not affected by external moisture. The weight method and Coulomb method for measuring hydrogen are greatly affected by external water vapor.

③High degree of automation, reducing the pressure on laboratory personnel

Can be loaded in one go29The sample is automatically injected and continuously injected, and the testing process is completed automatically without human supervision; Samples can be added during the analysis process, and the sample tray has a number display to avoid sample confusion. Sample trays with numbers are configured to facilitate the sequential placement of samples; The electronic balance weighing can be directly transmitted to the computer, eliminating manual input and reducing errors.

④Fast testing speed

The typical test time for a sample is300In seconds.
