Description
The HP Agilent G1322A Degasser supports a maximum flow rate of 0 to 10 mL/min per channel and is equipped with 4 independent channels, each with an internal volume of 1 mL. It is designed with durable materials in contact with the solvent, including PTFE, PEEK, and FEP, ensuring compatibility across a wide range of applications.
The degasser operates effectively within a pH range of 1 to 14, making it suitable for diverse analytical needs. It utilises a micro vacuum degassing system to remove dissolved gases, enhancing performance and accuracy in liquid chromatography. For pressure monitoring, the degasser features an analog output (AUX) range of 0 V to 3 V, enabling precise tracking and integration with external systems.

Negative Effects of Dissolved Gas in Mobile Phase:
- Unstable pumping conditions cause unstable flow, which may lead to high ripple or significant standard deviations in peak retention times and peak areas, particularly at low flow rates.
- Changes in the refractive index create baseline noise on sensitive detectors.
- Dissolved oxygen degrades samples.
- Dissolved oxygen quenches fluorescence.
- Dissolved oxygen, especially in reduction mode, causes baseline drift in electrochemical detectors.
