This gas chromatograph combines the best features of various models to offer a highly cost-competitive unit. It incorporates a 5-inch touchscreen, precision flow path control (with stable pressure and flow regulation), digital circuitry, IP communication, bus technology, network transmission, and RS-485 digital data transfer. These features enable online chromatographic analysis and remote control capabilities.
1. Features automatic FID ignition and flame-out monitoring, eliminating the need for manual triggering; ignition frequency is automatically controlled based on temperature, and ignition thresholds are fully customizable.
2. The TCD includes pre-amplification settings (2x, 4x, 6x, and 8x) to ensure high sensitivity, making trace analysis straightforward.
3. Intelligent control of the rear-door automatic cooling system adjusts the opening angle via temperature compensation; this replaces traditional mechanical triggering methods (such as limit switches or optocouplers) with a stable, reliable solution, providing robust performance assurance for users frequently performing temperature-programmed analyses.
4. Supports remote control via a networked chromatography workstation, allowing all instrument parameters to be managed through PC software; the system utilizes digital transmission and bidirectional communication—aligning with international standards—to ensure mature, stable performance while eliminating the need for external data acquisition cards. An analog output port is also included to accommodate existing users who wish to continue using older workstation versions, reflecting a user-friendly design.
5. Features a 5-inch LCD touchscreen, real-time Flash animation display, and dynamic rendering of realistic graphics.
