· A nobel optical system (three-chamber flow cwll) provides at least twice the sensitivity of our previous detectors.
· The double temperaturefluctuations.
· The limit of detection for saccharides is approximately 2 ng.
Prenciple of New optical system measurement
in our previous optical system, the measurement light through the flow cell was refracted onlr once. the new three-chamber flow cell allows the light to be refracted wice, thereby inceasing sensitivity at least tow-times at the same optical path length. this doubles the defection degree and results in not only reduces the noise half, but reduces the drift caused by optical systems half.
