GDGC-7890-DL High Sensitivity Transformer Oil Dissolved Gas Analyzer for Insulation Oil Gas Detection
Seamless Adaptation & Efficient Linkage
 | Precise matching between gas sources and chromatograph |
| The 99.999% purity of the hydrogen generator and the cleanliness of the air generator both meet the gas source requirements of GC-7890-DL, no additional adaptation devices needed, plug and play. |
| Closed-loop from pre-processing to detection |
| After the shaker completes sample degassing/mixing, it can be directly connected to the chromatograph for injection analysis, reducing sample transfer loss and improving detection efficiency. |
| Synergistic stability of pressure and flow |
| The 0.005Mpa pressure stability of the hydrogen generator and 0.003Mpa pressure stability of the air generator complement the pneumatic control system of the chromatograph, ensuring detection repeatability. |
Focus on Details to Ensure Performance
Hydrogen Generator: Advanced membrane penetration technology + gas-liquid separation device, realizing efficient electrolysis and alkali-free output; switching power supply improves electrolysis efficiency and reduces energy consumption.
Air Generator: 13X silica gel + activated carbon double purification to deeply remove impurities and moisture; dual-stage pressure regulator + over-temperature/over-pressure double protection, balancing purity and safety.
GC-7890-DL: 7-step temperature programming + ±0.1℃ temperature control precision, FID detector sensitivity ≤1×10⁻¹²g/s, TCD sensitivity ≥8000mv·ml/mg, meeting trace and constant analysis needs.
Multi-Function Shaker: Digital PID temperature control technology, 275±3 cycles/min stable oscillation frequency, 35mm amplitude design, ensuring sample mixing uniformity and thorough degassing.
One-Stop Meeting Detection Needs
Petrochemical Industry: Transformer oil dissolved gas detection (GC-7890-DL with gas sources), oil component analysis; the shaker preprocesses samples to improve detection accuracy.
Food and Pharmaceutical Industry: Food additive residue detection, drug purity analysis; high-purity gas sources and high-precision chromatograph ensure reliable detection results.
Environmental Monitoring: Atmospheric pollutants, water quality harmful substance detection; the complete set of equipment is suitable for laboratory batch sample analysis with higher efficiency.
Scientific Research and Education: University research, daily detection of quality inspection institutions; supports custom modes and multiple detectors to meet diverse experimental needs.
