Performance parameters of GC 2000

GC 2000 is a special-purpose detection and analysis instrument for laboratories based on the basic principle of gas chromatography. It adopts the advanced electronic flow pressure control system, microfluidic plate control technology. high-precision independent temperature control system, and high-sensitivity detector, which, in combination with the flexible and friendly user interface, high-speed sampling frequency and signal processing speed, and networked data and control platform, meet the user’s requirements for the capability. reliability, stability and advanced nature of instrument analysis.

Chromatographic performance:

Retention time repeatability < 0.008%
Peak area repeatability <0.5%

Our Core Strengths

Supporting simultaneous installation:
a.Two injection ports
b.Four detectors
c.Three detector signals
Electronic digitized data output of the advanced detector, enabling quantitative analysis of peaks over the full range of the detector in a single injection
Electronic flow control for all injection ports, detectors, and auxiliary gas flow circuits
Possible for up to 6 electronic flow control modules to be installed, to provide control over up to 18 gas circuits. Accuracy of pressure setpoint and control approaching 0.001 psi, providing more accurate retention time for low pressure analyses.
Electronic flow controller for capillary columns with five column flow control modes: Constant pressure, pulse, and programmed pressure rise and flow increase to the fourth order; possible to calculates the average linear velocity of the column.
Standardized pressure and temperature compensation to keep test results remain unchanged even when the laboratory
environment changes.
Possible for users to automate leak checks before each run, or run the check function at any time during maintenance or diagnostics. Users are alerted when a leak is detected so that immediate action can be taken to correct and reduce system
downtime.
