| A new refractive index (RI) detector series is now available. RI-201 is a highly sensitive RI detector incorporating a three-chamber flow cell. |
 |
|
-
(Features
-
A nobel optical system (three-chamber flow cwll) provides twice or better sensitivity than of our previous detectors.
-
The two-step temperature control method significantly reduces drift due to the flucturation of room temperature.
-
The detection limit for saccharides is approximately 2 ng
