3、 Scheme description

1. The accessories mentioned in this plan are all original VALCO accessories, including pipelines and six way valves.

2. The chromatograph described in the plan is equipped with * carrier gas protection and gas path protection functions. In the event of a gas outage, the instrument automatically shuts down for temperature control, which can prevent the chromatographic column from being burned out in the event of a gas outage, achieving the effect of protecting the chromatographic column. At the same time, the chromatograph cannot start heating without a carrier gas, preventing operators from accidentally damaging the chromatograph.

3. It adopts * 10/100M adaptive Ethernet communication interface and built-in IP protocol stack, which is convenient for enterprises to realize long-distance data transmission through internal LAN and Internet; Facilitating laboratory setup, simplifying laboratory configuration, and managing data. At the same time, the software comes with MODBUS and 4-20mA transmission functions.

4. All analysis results will be automatically saved and uploaded to DCS after the data analysis is completed.

5、 The FV3320 FID detector has an automatic ignition function when powered on, without the need for manual operation

6The flow rates of hydrogen, air, and tail blowing are automatically displayed for easy maintenance.

7After the flame is extinguished, it has an automatic key function to ensure safety

8Automatic over temperature protection function to prevent damage to components

9Adopting a high-sensitivity FID detector, it has high sensitivity, simple maintenance, low gas consumption, and saves gas

10Equipped with automatic injection function, software controls automatic switching of injection, and the injection interval can be adjusted according to actual needs; Using imported sample valves from the United States, the operation is stable and reliable.

11The system's hydrogen and air flow rates are all displayed electronically, unaffected by changes in environmental pressure and temperature, and the readings are accurate and reliable; The control accuracy of the column box is better than ± 0.05 ℃, and the reproducibility is good.

12The chromatographic analyzer adopts the American Valco ten way valve, which has a small volume, can be operated up to 1 million times without maintenance, low maintenance, and long service life;

13、The analysis section includes a pre column and an analysis column. The chromatography column is filled with imported Waters Sepuco stainless steel, which has good separation efficiency and long service life;

14、 The FV3320 chromatography industrial computer comes with a power switch that can be directly hot started without affecting the analysis of the chromatography instrument.

15、 FV3320 is equipped with an automatic injection system and a heating and insulation system, which can ensure residue free analysis of high boiling point substances, improve analysis accuracy and repeatability.

16Excellent graphical human-computer interaction interface and * data processing function; Built in industrial PC, high-definition color LCD touch screen display; Adopting excellent human-computer interaction control software interface, based on Microsoft Windows operating system; All maintenance and diagnostic functions can be completed using the touch screen, and instrument parameters and analysis methods can also be edited and set;

17Real time display of instrument operating status, chromatograms, results, and alarm information, etc; Automatically store data and graphs for up to 3-5 years.
