FAQ
Why does the GC-SK5190 FID detector utilize ignition components and nozzles made of platinum?
A: Platinum’s exceptional chemical inertness and resistance to high-temperature oxidation offer customers 3 key benefits:
1. Platinum does not oxidize or release volatile metal impurities in high-temperature hydrogen flames, minimizing baseline noise and drift to the absolute limit.
2. It eliminates the need for frequent maintenance and replacement; platinum components have an extremely long service life and rarely require changing.
3. It ensures a 100% ignition success rate and consistent data, resulting in experimental data with outstanding reproducibility.
What is the working principle of gas chromatography?
The fundamental concept of gas chromatography involves introducing the sample solution into a gas flow, which then carries the sample into a separation column. This column facilitates the separation of the different components of the sample. Helium or nitrogen typically serves as the carrier gas for this process.
Is a gas chromatograph the same as a mass spectrometer?
No, a gas chromatograph (GC) and a mass spectrometer (MS) are not the same. While both are analytical instruments used in chemistry, they serve different functions.
A gas chromatograph separates and identifies components of a sample mixture based on their differential partitioning between a stationary phase and a mobile phase (gas), whereas a mass spectrometer identifies and quantifies individual compounds within a sample based on the mass-to-charge ratio of ions produced from the sample's molecules. Often, these two instruments are used together in a technique called gas chromatography-mass spectrometry (GC-MS) for comprehensive analysis.
What are the technique of gas chromatography?
The method primarily entails vaporizing a sample by heating it until its constituent compounds enter the gas phase. Subsequently, the components are separated through chromatography, and the individual compounds are detected and quantified using a detector and software system.
