Product Description
GDGC-7890-DL High Sensitivity Transformer Oil Dissolved Gas Analyzer for Insulation Oil Gas Detection
GC-7890-DL Gas Chromatograph
Supports FID/TCD detectors, high-precision temperature control from room temperature +5~400℃, compatible with packed columns and capillary columns, meeting accurate multi-component detection needs.
Multi-Function Shaker
±0.5℃ precise temperature control, preset degassing/mixing programs, supports custom modes, providing standardized pre-processing for chromatographic detection.
Hydrogen Generator
99.999% high-purity output, 0~350ml/min adjustable flow rate, alkali-free design + over-pressure protection, providing stable gas source for gas chromatography.
Air Generator
Replaces high-pressure gas cylinders, dual-stage pressure stabilization + automatic water drainage, noise ≤42db, compatible with GC and nitrogen generators, ensuring clean and dry gas source.
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. |
