The AELAB GC126N Gas Chromatograph integrates a 7-inch color touch screen with a friendly man–machine interface, providing smooth control and efficient operation. The system utilizes multi-core 32-bit embedded hardware to ensure reliable and stable analytical performance. Carrier, hydrogen, and air flow are monitored via a digital pressure display, enabling accurate regulation across chromatographic workflows.
The GC126N incorporates gas-shortage and heating-control protection, dual-channel data acquisition with 50 ms sampling, logarithmic amplification for stable signal output, and external trigger functionality. With eight event extension interfaces and RJ45 network connectivity, the instrument supports external automation, remote data management, and seamless sampler integration.
The AELAB GC126N features a temperature-controlled column oven capable of 5°C to 400°C operation with ±0.1°C accuracy and up to nine programmable temperature ramps. The detector modules—including FID, TCD, ECD, and FPD—are built for stable high-temperature use, with dedicated heating zones for injectors, detectors, and auxiliary channels. The robust mechanical frame and modular design support long-term analytical reliability and easy maintenance.
The GC126N performs quantitative and qualitative separation by transporting vaporized analytes through a temperature-controlled column using a regulated carrier gas. Dual-channel acquisition processes chromatographic signals at high speed, while the selected detector (FID, TCD, ECD, or FPD) converts chemical or physical interactions into measurable electrical outputs. Users can execute split/splitless, constant-pressure, or PTV-assisted injection depending on sample requirements.
The system includes Ethernet (RJ45) for network communication, external event triggers, multi-port I/O support, and compatibility with third-party gas chromatograph autosamplers. Data can be exported to laboratory information systems, enabling GLP-compliant workflow documentation.
