The general detection range of the gas chromatograph is often equipped with a detector

General: GC9800 Gas Chromatograph Manufacturer: Jinan Fine Electronic Technology Co., Ltd.Gas stove

TCD detector (thermal conductivity cell detector)

One of the most widely used detectors for inorganic gases and organics, suitable for constant analysis or analysis of components of more than 100,000 parts, such as:

(1) Constant analysis of natural gas O2, N2, CH4, CO2, C2H6, C3H8, i-C40, n-C40, i-C50, n-C50, etc. for urban gas;

(2) Determination of main components such as H2, O2, N2, CO2, CH4, C2H4, C2H6, C3H6 in artificial gas;gas stove

(3) Analysis of the composition of C2-C4 and total C5 hydrocarbons in liquefied petroleum gas produced by refineries (excluding diolefins and alkynes);

(4) Analysis of gaseous hydrocarbon components below C5 in liquefied petroleum gas (excluding alkynes);

(5) Qualitative and quantitative analysis of benzene and toluene in gasoline;

(6) Transformer oil cracking products;

(7) Rapid analysis of refinery H2, O2, N2, CO2, CO, C10-C60, C2 di-C4 di and C6 and above hydrocarbons;

(8) Detection of moisture and nicotine content in the total particulate phase of the flue gas;

FID detector (hydrogen flame ionization detector)

High sensitivity, suitable for microanalysis of organic matter, such as:gas stoves

use:

Rapid analysis of refinery H2, O2, N2, CO2, CO, C10-C60, C2 di-C4 di and C6 and above hydrocarbons;
Qualitative and Quantitative Analysis of Benzene and Toluene in Gasoline
Analysis of certain alcohols and ethers in gasoline. Particularly suitable for the analysis of alcohols and ethers in automotive and aviation gasoline and gasoline containing ethanol
Analysis of methanol and fusel oil in liquor
Detection of trace components such as methanol and fusel oil in edible alcohol
The analysis of the main components of alcohol, aldehyde, acid and ester in Luzhou-flavor liquor and fragrant liquor was completed. In addition to improving the analytical efficiency, the capillary column can also detect organic acids, providing more valuable information for complex brewing fermentation processes.
Detection of residual solvents in vegetable oil
Detection of benzene, toluene, xylene and total volatile organic compounds (TVOC) in indoor air
Transformer oil cracking product (8 component gases) automatic analysis of one injection
Detection of water and nicotine content in total particulate phase of tobacco smoke

ECD detector (electron capture detector)

It is a low-energy radioactive detector. It is widely used in the detection of pesticides, atmosphere and water pollution. It is suitable for analysis: organic compounds of halides, polysulfides, polycyclic aromatic hydrocarbons and metal ions. such as:

Determination of formaldehyde in indoor air
The test for chloropropanol in food can be determined by trichloroacetic anhydride derivatization combined with electron capture detector (ECD).
With reference to GB/T14551-93, an electron capture detector, with a capillary injection system and a dedicated large-diameter capillary column, can be used to detect organochlorine pesticide residues in tea.
Determination of pesticide residues such as organochlorine in tobacco and tobacco products can be accomplished by using ECD detectors with different capillary columns.
Pesticide residue detection

FPD detector (flame photometric detector)

It is suitable for the analysis of pesticides containing sulfur and phosphorus and for monitoring trace sulfur and phosphorus organic pollutants in environmental analysis, such as:

(1) Determination of pesticide residues such as organophosphorus in tobacco and tobacco products can be accomplished by using FPD detectors with different capillary columns.

NPD detector (nitrogen phosphorus detector)

It is a mass detector for high sensitivity and high selectivity detectors for the analysis of nitrogen and phosphorus compounds; it can detect 5×10 (-13 times) g/s azobenzene nitrogen compounds, 2.5×10 ( -13 times) g/s phosphorus compounds, such as marathon pesticides. It has a high response to nitrogen and phosphorus compounds. The response to other compounds is 10,000 to 100,000 times lower. Nitrogen and phosphorus detectors are widely used in pesticides, petroleum, food, pharmaceuticals, spices and clinical medicine, such as:

(1) Determination of pesticide residues such as pyrethroids in tobacco and tobacco products can be accomplished by using NPD detectors with different capillary columns.
