Characteristics of CG-CF11 Rod Thin Layer Chromatography Instrument

●simplicity:This instrument has the characteristics of easy operation, fast analysis speed, short analysis cycle, and accurate analysis data.

●environmental friendliness:Due to the use of toluene as a solvent and minimal dosage, it greatly reduces the harm to human health, which is beneficial for environmental protection and the health of operators.

●economy:The chromatography rod can be reused, usually 50 times, and only requires a small amount of solvent during the development process, with very low cost.

●generality: YesA large number of organic compounds can be directly detected, including high boiling point samples that are difficult to use for gas chromatography analysis. Widely used in fields such as medicine and health, environmental chemistry, petrochemicals, petroleum geology, coal chemistry, and fine chemicals.

The working principle of the instrument

Dilute organic samples that are non-volatile at room temperature and soluble when burned in flames with solvents and dot them onto thin layer rods coated with silica gel and alumina adsorption. After removing the solvents, place them in the corresponding unfolding slots and separate them under certain saturated vapor pressure conditions; After the sample is unfolded, the thin layer rod enters the FID in sequence and burns on the FID at a certain speed; The ion flow signal is collected and processed by a computer; Thus obtaining chromatographic analysis results.

Application of instruments

This instrument can detect all organic compounds, especially those that are difficult to separate by gas chromatography or analyze by liquid chromatography, as well as large molecular compounds in drugs, and track the process of organic synthesis reactions. Complex samples that are difficult to detect by gas chromatography and liquid chromatography methods can be detected under open conditions. And it is very easy to quantify the analyzed samples.

Mainly applied in the following research: lipids, phospholipids, waxes, fatty acids, synthetic lipids and synthetic oils, lubricants, lubricating oils, surfactants, various industrial lipidsCrude oil, heavy oil, residue oil, wax oil, slurry oil, lubricating oil, base oilchromatographyfixativeAsphalt, residual oil, various hydrocarbon substances, polymers, edible oils, pharmaceutical reagents.

This instrument is suitable for those certified by the Chinese petroleum and natural gas industry standards in 2008《SY/T5119-2008Thin layer flame ionization analysis method for soluble organic matter and crude oil group components in rocks

This instrument is applicable to the "SH/T0753-2005 Lubricating Oil Base Oil Chemical Composition Determination Method" certified by the National Standard of the People's Republic of China in September 2005

Advantages compared to traditional column chromatography in crude oil component analysis

1The two data are comparable.
2. Due to the high degree of automation and intelligent detection methods of FLC/FID method, its accuracy and precision are significantly higher than those of column chromatography.
3. Column chromatography can only analyze samples above 0.1g, while TLC/FID method can normally analyze samples between 0.1-1.0ug, with a detection yield of only 1x10-6. While meeting the requirements of constant analysis, it can also be used for trace analysis;
4. Column chromatography requires a large amount of organic solvents to analyze the composition of saturated hydrocarbons, aromatic hydrocarbons, colloids, asphaltenes, etc. (with asphaltene using the superposition method), resulting in a long analysis cycle and low accuracy of analysis results. However, TLC/FID method only consumes 1 ‰ of organic solvents, has a short analysis time of less than 60 minutes (10 samples can be taken at a time), and the accuracy can reach the ppm level.
5. Comparing the two methods, TLC/FID improves the analysis efficiency by more than 30 times, expands the applicability range of pre-processing and post-processing of the analysis method, saves a lot of reagents, and improves the working environment.
