Application of Gas Chromatograph:
GC-900 gas chromatograph is a popular, high-performance, multi-functional series of chromatographic instruments. FID, TCD and FPD detectors can be combined as needed to meet the needs of ordinary laboratories, daily production, routine detection and trace quantities analysis requirements. It can be widely used in many fields such as petroleum, chemical industry, environment, food safety, disease control, teaching and scientific research.
Gas Chromatograph Feature:
The inlet can be installed up to 4 types (packed column, capillary column split/splitless injection system can be used), multiple detectors with the same or different detectors are installed, automatic/manual gas injection device can be selected, top Empty sampler, thermal desorption sampler, pyrolysis furnace sampler, methane reformer, etc.
The intelligent rear door system has stepless variable inlet and outlet air volume, which shortens the stable balance time of the system after programmed heating/cooling
Unique vaporization chamber design, smaller dead volume; replacement of accessories such as injection pad, liner, polarizer, collector, nozzle can be done with one hand; packed column, capillary injector, TCD, FID detector and other main bodies. The replacement only requires a wrench to be completely disassembled, and the maintenance is very convenient.
Ethernet communication interface is adopted, so that the instrument can realize long-distance data transmission through the internal LAN of the enterprise, which is convenient for the management of analysis data
The unique design of the injection port solves the injection discrimination, and the dual-column compensation function not only solves the baseline drift caused by temperature programming, but also reduces the influence of background noise, which can lead to lower detection limits.

FAQ
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.
