Lab Gas Chromatograph Transformer Tester Dissolved Gas Analysis FID TCD ECD FPD 400C| XHSP1700

The XHSP1700 lab universal gas chromatograph is a high-resolution, multi-detector analytical instrument designed for laboratory use. It supports up to three detectors simultaneously from the FID, TCD, ECD, FPD and NPD series, with 6-way temperature control, 16-order temperature programming and EPC/EFC electronic pneumatic control, delivering accurate and reproducible results for complex sample analysis.

In the transformer industry, the XHSP1700 is an ideal solution for dissolved gas analysis (DGA) of transformer insulating oil. By quantifying the characteristic fault gases such as hydrogen, methane, ethane, ethylene, acetylene, carbon monoxide and carbon dioxide dissolved in transformer oil, it helps power utilities diagnose latent faults including overheating, partial discharge and insulation aging at an early stage, so that maintenance can be planned before a failure occurs.

Beyond transformer oil testing, it is also widely used in petroleum, chemical, environmental, food and pharmaceutical laboratories as a general-purpose gas chromatograph.

The instrument combines high resolution, wide dynamic range and stable retention time reproducibility. Its modular structure allows flexible configuration of injectors, detectors and gas control systems, so the same platform can be adapted from routine quality control to advanced research applications, protecting the laboratory's instrument investment.

The XHSP1700 supports decentralized detection, which means multiple instruments can be deployed at different sites, such as regional transformer oil testing stations or field laboratories, while measurement results are uploaded and managed centrally through the Ethernet IEEE802.3 communication interface. This distributed architecture is particularly valuable for power grid companies that operate oil testing laboratories across several provinces or for group laboratories that need uniform data management.

The external events (4 in / 4 out) with auxiliary control output allow the chromatograph to be integrated with autosamplers, headspace samplers and other automation peripherals, forming a fully automated analysis workflow that improves throughput and reduces operator error in busy laboratories.

In transformer condition assessment, the concentrations and relative ratios of characteristic gases dissolved in insulating oil are the basis for diagnosing latent faults. Hydrogen indicates partial discharge and low-energy arcing, methane and ethane indicate thermal faults at low and medium temperature, ethylene indicates high-temperature overheating, acetylene indicates arcing discharge, and carbon monoxide and carbon dioxide indicate paper insulation aging. The XHSP1700 quantifies these gases with high resolution and reproducibility, supporting DGA standards such as IEC 60567 and GB/T 17623.

With its high-sensitivity FID, TCD and ECD detectors, the instrument is also widely used in petroleum, chemical, environmental monitoring, food safety and pharmaceutical analysis, covering most routine and research GC applications in a single universal platform. The FPD detector provides selective and sensitive measurement of sulfur and phosphorus compounds, which is especially useful for pesticide residue analysis and environmental monitoring of organophosphorus and organosulfur pollutants.

Each unit is delivered with a warranty certificate and after-sales service support, and customization is available to match specific project requirements.
