Networked gas chromatograph

GC2090 typeNetworked gas chromatograph

The entire system is equipped with EPC and EFC control systems, which are designed and manufactured as gas micro flow control systems using high-precision proportional valves, pressure sensors, and flow sensors. Compared to traditional mechanical valve control methods, it greatly improves the accuracy of gas pressure and flow control, enhances the automation level of instruments, eliminates the shortcomings of traditional mechanical valves that cannot compensate for temperature, and thus improves the overall performance of instruments!

Anti control chromatography workstation
Unlike ordinary gas chromatographs, it requires a 10/100M adaptive network environment (when remote data transmission through the Internet is required, Internet access services are also required) and a set of computers with Chinese Windows 2000, XP, win7, and win8 operating systems.

Building a network environment is very simple. If the user's laboratory already has a network environment (with IP remaining in this network environment), the instrument can be directly connected to this network using Ethernet cables. If the user's laboratory does not have a network or intends to isolate the instrument's network from the office network, a network can be constructed using switches, HUBs, etc. Switches, HUBs, etc. can be purchased from local computer stores, or from manufacturers or distributors when ordering instruments.

The reverse control chromatography workstation can modify and set any parameters within the GC2090 host.

[Precautions for Operation]

During the operation or shutdown of the instrument, components such as the injector, detector, column box, and rear air outlet may experience certain high temperatures, and should be avoided from coming into contact with them to prevent damage. If parts need to be replaced, be sure to wait until the instrument temperature drops or after using protective measures!

Pay attention to the burning gas emitted during instrument cooling to prevent tank damage;

Flammable materials are strictly prohibited from being placed on the back of the instrument to prevent the release of hot gases from igniting flammable materials!

PVC and other gas pipelines should avoid the rear air outlet of the instrument to prevent the burning gas from melting the gas source pipeline and causing danger! Gas source hazard:

For the gas cylinders and sources used in the instrument, relevant regulations on gas cylinder transportation, storage, management, and overall use should be followed.
