SF6 new gas analysis gas chromatograph

Product Description:

SF6 gas is mainly used in the power industry. SF6 gas is used for insulation and/or arc extinguishing in four types of electrical equipment; SF6 circuit breakers and GIS (referring to SF6 enclosed composite electrical equipment, internationally known as "Gas Insulated Switchgear"), SF6 load switchgear, SF6 insulated transmission pipelines, SF6 transformers, and SF6 insulated substations. 80% is used for high and medium voltage electrical equipment.Before injecting sulfur hexafluoride gas into power equipment, the testing department needs to analyze the injected sulfur hexafluoride to determine whether the new gas meets the standard requirements,GC-6600 SF6 new gas analysis gas chromatograph mainly analyzes air, carbon tetrafluoride, hexafluoroethane, and octafluoropropane.

★1.1 New networked control and transmission to achieve real-time monitoring and data collection by multiple people:

Equipped with a 10/100M adaptive Ethernet communication interface and built-in IP protocol stack, the instrument's PI address can be set to remotely access the chromatograph through the network,The instrument can realize remote control of the chromatograph and data transmission of the collected spectrogram through the enterprise internal LAN and the Internet;^instrumentThree independent connection processes are designed internally, which can be connected to the local processing (laboratory technician), unit supervisor (team leader), and superior supervisor (special supervisor, chief engineer, etc.) through the Internet, which can facilitate multiple people to monitor the operation of the instrument and analyze the data results in real time, and improve the cooperation and timeliness of work.★1.2 Multiple workstations control, enabling one computer to simultaneously monitor N gas chromatographs

The GC-6600-F instrument is equipped withNETChrom

TM

Workstation, capable of supporting multiple chromatography instruments to simultaneously process and control data, reaching the industry's highest levelEffectively solved the problem of too many computers in the laboratory and released experimental space.

The analysis parameters of the sulfur hexafluoride analyzer, including carrier gas pressure, sample pressure, temperature, etc., are set or displayed through a workstation, which is easy to operate and provides real-time monitoring of the analysis conditions.

1.3 Adopting central cutting technology to achieve high automation of the instrument:

Adopting a dual quantitative tube injection and purging technology with 2 imported automatic drive valves and 3 chromatographic columns, the injection, switching, column selection, and reflux processes are automatically controlled through the time program set by the workstation. One injection can complete the separation, selection, and detection of complex samples.★

1.4 Digital electronic zeroing technology enhances the anti-interference ability of instruments:

The detector signal zeroing adopts electronic zeroing technology, using high-precision digital circuits for base current compensation to achieve electronic adjustment of output signal level, reducing parasitic parameters and thus having strong anti-interference ability.

1.5 Automatic gas cut-off protection function to ensure the safe operation of the detectorEquipped with intelligent gas cut-off protection function, when the carrier gas pressure is below the safety threshold, the system will automatically cut off the detector voltage and the chromatograph will automatically cool down to protect the detector and chromatographic column from damage.★

1.6 Industrial 5.7-inch color screen, Chinese LCD display₂The display window adopts a 5.7-inch industrial color LCD screen design, which displays more comprehensive information, the interface operation is more reasonable, the display is intuitive, and the operation is convenient; The spectrum display function abandons the fragile and low-end PVC leather buttons and adopts plastic mold buttons, which have a good hand feel and are durable.₂1.7 Standard gas₄The instrument quantification adopts the mixed standard external standard method. One bottle of mixed standard gas should contain at least the following components, and the range of standard gas components should be controlled within₂200～600ppm₆between:₃Oxygen (O)₈）Nitrogen (N)
