Shanghai manufacturer of methane non methane total hydrocarbon analyzer Instrument principle:
Sample Sampling System:
Gas path atmospheric sampler is a conventional instrument for parallel sampling of harmful gases. The device adopts dual pumps to independently complete two sets of gas paths without interference. The circuit is controlled by microcomputer chip technology and has a built-in high-energy lithium rechargeable battery. It has a long continuous operation time, easy operation, high timing accuracy, durability, compatibility with AC and DC, and convenient and fast timing selection. Countdown time range of 1-99 hours and 59 minutes can be freely selected
Sample analysis:
The fully automatic thermal desorption instrument is a new generation of fully automatic thermal desorption instrument with fully automated design, touch screen display, and more convenient operation, capable of continuously running 10 samples. Normal temperature secondary desorption components or low-temperature secondary desorption components can also be added according to user needs.
Gas chromatograph analysis:
The instrument adopts a fully microcomputer control system, and the bus control platform of * can modularize and expand the chromatographic system; Large screen LCD display in Chinese/English, displaying rich and intuitive content; New digital design, highly integrated electronic circuit, excellent reliability and anti-interference ability, Chinese keyboard style operation, convenient parameter setting and operation. This instrument can be widely used for routine analysis of control and detection in power, environment, medicine, pesticides, petroleum, coal, commercial inspection, epidemic prevention, universities, scientific research, and chemical industry. It can also be modified into a chromatograph according to different user needs.
Workstation data processing and output:
The workstation automatically recognizes solvent peaks, tailing peaks, sawtooth peaks, front and back shoulder peaks, and automatically adjusts parameters (peak width, slope) during the analysis processBaseline automatic tracking, automatic classification of chromatographic peak types; Peak rise and fall pointsPowerful manual integration function, peak addition and subtraction, peak baseline adjustment, cutting method adjustmentIntegral sensitivity of 1 microvolt · s, maximum small resolution of 0.1 microvolts, maximum small peak width of 0.1 secondsThe data results can be shared with software such as Microsoft Excel and Word; Data spectra and PhotoshopQuantitative calculation methods: normalization method, calibration normalization method, internal standard method, grouping method, external standard method, index method.
