Two: GC-7860 Network Version Anti-Control Workstation:

Features and Functions:

1. *Communication Methods: Network-based communication, IEEE802.3 Ethernet interface; workstations also support RS232 communication interface.
2. The integration of chromatography data processing and instrument reverse control operations ensures easy operation and a user-friendly interface.
3. ▲Workstation software allows for the setting and control of parameters such as the temperature of the heating zone, user-defined names for the heating zone, enable switches, gas flow and pressure, program voltage control, program heating and external events, automatic sampler, multi-channel sample selection control, and detectors.
4. ▲Workstations support multi-channel data processing for multiple chromatographs, designed to accommodate connections for up to 5,000 chromatographs. Each chromatograph's data processing supports four-channel signal handling, with the fourth channel being a virtual channel for convenient display of multiple detector signals on a single spectrum and featuring a straight baseline function.
5. The workbench software features an integral time program setting with practical functions such as baseline locking, negative peak identification, and negative peak inversion.
6. Data analysis results can be converted into Word format for easy printing, output, and copying.
7. Automatically generates folders named by chromatograph models and timestamps, facilitating simultaneous management of multiple chromatographs for users.
8. The 7866NetChorm Network Edition Anti-Control Workstation can remotely transmit analysis results to where the user needs them via various transmission methods (Internet, CAN Bus, MODBUS Bus, GPRS Communication, 3G Communication, Wireless Special Networks, etc.).
9. Data analysis can conveniently upload to the DCS system, featuring a 4mA to 20mA output for easy industrial online closed-loop control.
10. Utilizing multithreading technology to enable simultaneous coordination of signal collection, data processing, and user management.
11. Software architecture supports rich configuration for multiple monitoring seats within a single system; each spectrometer supports simultaneous access from three IP addresses.
12. Equipped with an extended communication interface for analysis results, supporting user secondary development and feature expansion.
13. PeakSmart Intelligent Recognition Technology, reduces the number of spectrum processing parameters that need to be set by users, and basically achieves automatic processing of peak detection, baseline correction, and overlapping peak segmentation.
14. The CDF files compliant with A/A (American Analytical Society) standards can be read for sampling data, thereby interfacing with chromatography workstations such as Agilent and Waters.
15. Utilizing high-fidelity digital filtering algorithms, it boasts robust noise immunity, capable of detecting weak peaks on par with baseline noise.
16. Data processing includes: normalization, corrected normalization, single-point correction (single-point internal standard method, single-point external standard method), and multi-point correction (multi-point internal standard method, multi-point external standard method).
17. The 7866NetChorm Network Edition Workstation can also be equipped with a "Component Content Monitoring System," which completes the statistics, analysis, and monitoring of chromatographic component content. It is suitable for chemical product production (such as reactions,分流, distillation, etc.) to conduct data statistics, content trend analysis, threshold detection, and threshold alarms for various components of samples. This makes the trend of component content changes clear at a glance. Data from the day or shift are automatically archived, eliminating the need for manual spectrum analysis, manual spectrum organization, and manual result judgment, thereby improving the factory's level of automation.
