GC-7890 Electric Oil Gas Chromatograph GC

Introduction:

• The GC-7890 Electric Oil Gas Chromatograph GC is a specific analysis instrument for transformer oil;

• GC-7890 Electric Oil Gas Chromatograph GC is a versatile designed for insulating oil dissolved gas content of the gas chromatograph analysis;

• GC-7890 Electric Oil Gas Chromatograph GC uses advanced double-column parallel, serial thermal conductivity detector, methane reformer, hydrochlorothiazide flame detector gas flow path can be completed in a single injection of insulating oil dissolved H2, O2, N2, CO, CO2, CH4, C2H4, C2H6, C2H2 composition analysis

• GC-7890 Electric Oil Gas Chromatograph GC is powerful, good separation, high sensitivity, good reproducibility, easy operation, low failure rate, attractive appearance, it can fully meet the need of transformer oil dissolved gases analysis;

Specifications:

Configuration:

• Gas source:

1. Nitrogen gas cylinder(40L gas cylinder + purity nitrogen + pressure relief valve)

2. Hydrogen Generator

3. Air Generator

• GC-7890-DL transformer oil analysis specific gas chromatography: (A host, thermal conductivity detector, hydrochlorothiazide flame detectors, conversion furnace, three columns).

• Dedicated transformer oil chromatography workstation

• Automatic multi-functional oscillator

• Standard gas(8L gas cylinder + gas + pressure relief valve)

• Computers and printers

• Toolkit(Pipes, fittings, spare parts, tools, syringes, needles sided, plastic caps,etc.

Features:

• Large LCD display, keyboard input, display various parameters such as temperature, flow, etc., with real-time monitoring;
• Automatic monitoring of the implementation of the heating zone. If heating zone is over temperature, heating power will be cut off automatically;
• With stop gas protection function. When the carrier gas pressure is less than 0.1MPa, heating power will be cut off automatically;
• With parameter storage function. The instrument will automatically run by the state of last shutdown, to achieve a true "one key to boot" function, or power meter will restore power automatically revert to the state before power on.
• With a self-diagnostic function, the instrument operating parameters in real-time detection, when the system is abnormal, the computer system will automatically protect the instrument.
• High re-producibility and pneumatic regulator system uses a unique process design, reduce the gas injection pressure fluctuation impact on the detector, thus maximizing the impact of reducing the impact of peak analysis to ensure the high accuracy of analysis.
• The machine has changed the traditional three-box design, but using an advanced two-box design, the instrument look more clean and beautiful, and it also improve the safety of operation.
• Carrier gas, hydrogen, air pressure gauge are adopted;
• The main and key components are imported components to extend the machine's life and reduce maintenance costs.
• Inlets, detectors and conversion furnace are modular design, they are very convenient for disassemble, the person without operating experience can also easily remove and replace the parts;
• Large oven(291×284×260mm,21.5L) which is convenient to remove column;
