PS-9001 Gas Chromatograph

The PS-9001 gas chromatograph can be configured with a range of detectors to match your analytical needs across different fields. Its front inlet design supports multiple sampling methods, including headspace and thermal desorption sampling, for efficient analysis of a wide variety of samples.

1. Wide variety of detector modules
The system can be equipped with a range of detectors to meet the analytical requirements of different applications. The advanced injection port design supports multiple sampling methods, such as headspace sampling and thermal analysis sampling, enabling efficient analysis of a wide range of sample types.

2. Powerful detection expansion capability
The detector and associated control components use a modular, unitized design. The extended control mode system is plug-and-play.

3. Ultra-efficient rear door design
The intelligent rear door temperature control system ensures stable column chamber temperature across all zones. Cooling is fast and supports near-room-temperature operation.
The unit features an enhanced self-diagnosis function at start-up, with intuitive fault display. It also includes power-failure data protection, automatic screen saver, and anti-power-interference capability.
