N2000 gas chromatography workstation data system



The chromatogram-signal acquisition board of N2000 workstation is the bridge connecting the chromatogram and the computer. The chromatogram-signal acquisition board itself contains a single chip processing system which is set in a shielded shell alone, and equipped with independent external power supply, imported with original packaging 16/24 (optional) high-precision A/D (analog to digital) converter chip (which integrates PGA programmable magnification, Gaussian low-pass filtering, zero, full scale, background, disorders and other auto-correcting functions). Resolution: full scale +-1uv (ensuring the linear feature of full scale).

(1) Auto-zeroing function for temperature drift:

With the development of computer technology and the improving of chip integration, the computers

ran faster, which makes the temperature of computer cases much higher. The auto-zeroing function

for temperature drift, preventing the acquisition board from being influenced by the temperature

changes from outside and of the acquisition board itself, ensures the reproducibility of the

chromatogram analysis.

(2) Data error automatic calibration function:

Utilizing advanced dynamic memorizer to continually record and accumulate error data, it could

automatic calibrate while data acquisition, minimizing the impact of the errors.



The hardware of N2000 chromatogram workstation:

It could work as universal type chromatogram data workstation, and be connected to ordinary

chromatogram instruments including Shimadzu, Agilent, WATERS and etc.
