Injectors and Detectors
The advanced modular design of the Master GC components features outstanding flexibility and upgradeability. Any GC configuration can be easily modified or upgraded.
The Master GC allows the easy assembly of a complete range of injectors, including a large volume Split/Splitless (SL/IN), Programmable Temperature Vaporizer (PTV), and Packed (PK) injectors.
Up to three injection systems can be installed simultaneously.
The most popular GC injector features an outstanding design and thanks to the patented DFC provides excellent precision in split, splitless, and pulsed injection modes of operation. In addition, the post-injection carrier gas save mode is a valuable cost-saving feature. TU fulfill the user’s analytical needs a series of liner types are available, including liners suitable for SPME analysis.
Programmable Temperature Vaporizer - PTV
Phe proprietary PTV is particularly suggested when high sample integrity is requested. The sample is introduced by cold injection followed by vaporization eliminating possible sample discrimination or degradation.
The PTV achieves extremely fast heating rates of up to 1,000 °C/min and rapid cool down with ambient air. Cryogenic cooling options using either CO2 or N2 are also available for highly specific applications.

Fast GC Detectors
The Master GC features a wide selection of detectors, compatible with Fast GC applications, such as Flame Ionization Detector (FID), Electron Capture Detector (ECD), Nitrogen-Phosphorus Detector (NPD), Flame Photometric Detector (FPD), and the Master TOF MS Plus Time of Flight Mass Spectrometer. Further detection systems dedicated to conventional analyses are : Photo Ionization Detector (PID), Thermal Conductivity Detector (TCD), Micro TCD (uTCD), and Pulsed Discharged Detector (PDD).
The possibility to simultaneously use up to three detectors delivers exceptional flexibility and expands the system capabilities.
Flame Ionization Detector - FID
The most used GC detection system measures the ions produced by organic compounds during combustion. It is extremely sensitive with a wide dynamic range of seven orders of magnitude.
Thermal Conductivity Detector - TCD
Most of the early GC instruments were equipped with thermal conductivity detectors. They have remained popular, particularly for packed columns and inorganic analyses like H2O, CO, CO2, H2 and all inert gases.
Electron Capture Detector - ECD
The first option for environmental measurements, offers excellent performance in the determination of PCBs, pesticides, and other halogenated organic compounds.
Nitrogen-Phosphorus Detector - NPD
Due to its selective and sensitive response to nitrogen and/or phosphorous containing compounds, the system is commonly used to detect pesticides, herbicides, and drugs of abuse.
Flame Photometric Detector - FPD
Selectively detects compounds containing sulfur or phosphorous. Outstanding performances can be observed in the analysis of sulfur compounds in natural gas and organophosphorus pesticides in agriculture, food flavor and fragrance applications.
Master TOF MS Plus Detector
Performs fast acquisition rates (1,000 spectra/s) and wide linear range. In combination with Master GC, the system is the ideal solution for Fast GC and GCxGC analyses. In addition, the its proprietary software solution is based on an innovative platform for acquiring and processing mass spectral data. Original deconvolution algorithm capable to handle the large amount of information in a smart and effective way permits reliable identification of trace compounds even in complex matrices.
