Catalytic FID portable non methane total hydrocarbon VOC analyzer

Catalytic FID portable non methane total hydrocarbon VOC analyzerIt is a catalytic combustion/non combustion chamber portable or hanging wall multi-purpose analyzer, which adopts full heating, no cold point high-temperature circulation technology, is equipped with a high-temperature and efficient catalytic device, and uses dual FID detectors to simultaneously detect the concentration values of the total torch and non combustion chamber in the sample gas. It can display and calculate the concentration values of the total torch, non combustion chamber and non combustion chamber in real time. LD3001 can be used to monitor the total concentration of non A hospital torches, and is widely used in smoke emission monitoring, engine exhaust analysis, power plant, incineration plant, and mechanical waste treatment plant emission monitoring.

催化法FID原理:
The major difference between using catalytic oxidation FID method and chromatographic FID method is that it does not use chromatographic columns to separate the A hospital,
But instead, a high-temperature catalytic oxidation furnace (cutter) is used to separate the A hospital.

Technical indicators and parameters
Measurement method for composition of hydrocarbons - Catalytic+flame ionization detector (FID)
The measurement range is 0.1-1000mgC/m3 (CH4). The FID detector automatically determines the ignition flame state of the detector,
Detect a limit of 0.1mg/m3 for high automatic ignition and flame detection alarm function
Conversion rate~95%, sampling system fully heated throughout the process
Relative standard deviation:::; 2% (CH4) sampling flow rate 600mL/min
Repetitive 1% hydrogen metal hydride technology
Measurement accuracy three: t 0.2% standard gas A/C+air base gas
Linear i-Wu difference: t2% (CH4) electric j original AC power supply AC-220V, instantaneous total power 300w
Reaction time T90 running for 1.5 seconds (excluding heating of sampling tube)
technical advantage
Using the catalytic FID principle, with a built-in cutting device from the hospital, the entire process is high-temperature and the data is accurate;
The dual detector configuration of * has a measurement response time of less than 3 seconds for non hospital total monsters;
• Single auxiliary gas source, only requiring micro compressed hydrogen gas or solid-state hydrogen gas storage module;
Dual channel EPC pressure controller ensures consistency in the injection volume of the total torch and the first burner;
The USB flash drive directly stores all measurement data and instrument status information in Excel/CSV format;
Low maintenance costs, no consumable parts in the instrument, and a catalyst lifespan of over 2 years.
• Avoid weighing 20 kilograms, with a high handle design that is convenient for a single person to carry, and can be measured horizontally or vertically;
