Hplc gas chromatography mass spectrometry (GLPC/GC)
Hplc gas chromatography mass spectrometry (GLPC/GC)
Gas chromatography is a widely used analytical technique in chemistry for separating and analyzing compounds that can be vaporized without decomposition. It is commonly used to test the purity of substances, separate mixture components, and identify compounds. In preparative chromatography, GC can also be used to prepare pure compounds from mixtures.
- Temperature Control: The temperature control range is from room temperature + 7 ℃ to 400 ℃ with a precision of 0.1 ℃ increments. The program heating order number is 13, with a heating rate from 0.1 ℃ to 50 ℃ per minute.
- Detectors: The system supports multiple detectors including Flame Ionization Detector (FID), Thermal Conductivity Detector (TCD), Flame Photometric Detector (FPD), Electron Capture Detector (ECD), and Nitrogen–Phosphorus Detector (NPD). Each detector has specific detection limits, baseline noise levels, and other performance characteristics.
- The system features a third-order heating process suitable for multi-component sample analysis.
- The main control circuit uses an integrated digital electronic circuit with a temperature control precision of 0.01 ℃, ensuring stable performance.
- The design includes a large volume and an intelligent rear door opening system for rapid cooling, reducing system stabilization time after temperature changes.
- Users can recalibrate the furnace temperature and set maximum temperature and balance time.
- Unique sample entrance design addresses sample discrimination issues.
- Two sampling systems can be installed simultaneously, including filled column and capillary diverter systems.
- Optional components include automatic/manual gas injection valves, headspace injectors, heat analyzers, pyrolysis furnaces, and methanol converters.
- Double column compensation reduces program drift and background noise, achieving lower detection limits.
- The instrument features a large-screen LCD for intuitive operation.
- Includes startup self-diagnosis, stopwatch, operation timer, power failure storage protection, and keyboard locking functions.
- Supports installation of two detectors simultaneously, such as FID, TCD, ECD, NPD, and FPD.
- FID is designed for easy disassembly and cleaning.
- High resistance single column TCD offers high detection sensitivity and stable baseline stability.
- Input signals can be logarithmically amplified to reduce interference and improve sensitivity.
Catalog excerpts
Gas chromatography (GLPC/GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture (the relative amounts of such components can also be determined). In some situations, GC may help in identifying a compound. In preparative chromatography, GC can be used to prepare pure compounds from a mixture.

Performance characteristics. The third order process is heating up, which can satisfy the analysis demand of the multi-component of the sample. 1) main control circuit adopts new integrated digital electronic circuit, temperature control precision of 0.01 °C, the performance is more stable; 2) program heating: 13th order, heating rate 0-50 minutes /min;The incremental 0.1 C / min; The design of the box is further improved to facilitate the rapid cooling of the instrument. 1) the volume is large, and it is the intelligent rear door opening system, which reduces the stable balance time of the system...

1) unique sample entrance design solves the sample discrimination; 2) two sampling systems can be installed at the same time: filled column, capillary diverter/non-shunt injection system (with diaphragm cleaning function); 3) optional automatic/manual gas six - pass injection valve sampler, headspace injector, heat analyser, pyrolysis furnace, methanol converter. 4) double column compensation work can not only solve the program drift caused by heating, but also reduce the influence of background noise, and can get lower minimum detection limit. The operating interface of the instrument is simple...
