Constance - GAS CHROMATOGRAPHY

GAS CHROMATOGRAPHY

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).
