We have developed a portable non methane total hydrocarbon analyzer for this technology. The instrument can quickly detect the total hydrocarbon content through software and provide alarm prompts. At the same time, it can be easily connected to other laboratory instruments for joint use, achieving rapid monitoring of laboratory gas concentration.
The portable non methane total hydrocarbon analyzer adopts spectral analysis method. Unlike general gas chromatography analysis method, this instrument uses spectral analysis method for detection, without the need for external samples or professional technicians to detect the gas content emitted by the instrument. Its advantages are: simple and easy to operate, no sample contamination, and on-site operators' doubts about instrument malfunctions. No special training is required to use the instrument for detection and analysis.
Before determining hydrocarbon substances in gases, portable non methane total hydrocarbon analyzers such as gas chromatography or gas chromatography-mass spectrometry (GC-MS) technology can be used for detection. When the gas concentration is greater than 1 ppm, the measurement result is an effective value, and it is considered a qualified product if it is greater than or equal to 1 ng/ml; Less than 1 ng/m3 and less than 10 ppm are both qualified; Less than 0.01 mg/m3 ≤ 0.010 gm 3, not greater than 5 ng/ml. ≤ 50M3/s "; Meet the lower limit of national emission standards. Meet the requirements of national standards. Non methane total hydrocarbons are an essential class of organic compounds in industrial production and daily life. Their toxicity is stronger than other gases, but they are also a relatively safe, hygienic, and environmentally friendly organic compound. They can be measured using any instrument.
The portable non methane total hydrocarbon analyzer uses gas absorption spectrophotometry to detect its content. The main detection and analysis methods include gas chromatography and mass spectrometry for comparative testing (LC) analysis and result identification techniques In chromatographic analysis methods, it is mainly used for qualitative and quantitative analysis of organic compounds, organic substances, and gases, as well as for the detection of non methane in environmental monitoring departments and school laboratories. The scope of application is: (1) Gas chromatography is similar to industrial standard determination for organic substances; (2) The instrument adopts a small volume and light weight; High sensitivity of 0.05 ppm; High sensitivity; Wide measurement range; The accuracy is generally within the range of ± 0.5%, with an accuracy of up to 0.005 g/mL.
