Control system: designed for monitoring and controlling the instrument via the computer.
1.Column Compartment/oven with superior thermal performance, multistage (10 ramps)
programmed temperature control function. (supported by “control system”).
2.Advanced builtin data acquisition system , supporting real time instrument status monitoring,
detection signal acquisition and PC control.
3.Column oven accommodates up to 3 chromatographic columns, and supports quick heat‐up
and rapid cool‐down with automated back‐door opening.
4.Flexible sample introduction system: 3 sample injectors could be installed and operated
simultaneously with independent temperature control.
5.High sensibility and stability detector.
6.2 independent and analog signals output.
7.Clarity software, compatible with GLP/FDA21 CFR Part11 requirements and regulations.
(electronic records and signatures).
