Product parameters

Pressure Protection Method

The carrier gas system features pressure protection. When gas pressure drops below 0.1 MPa, the instrument automatically cuts off power to effectively safeguard column integrity and operational safety.

The FID incorporates automatic ignition functionality, eliminating the need for manual ignition.
