1 The ACQUITY Refractive Index Detector

Range and attenuation

The total refractive index range of the detector is 1.00 to 1.75. However, for
optimum performance, the usable solvent refractive index range is 1.24 to
1.60. The measurement range of the instrument is 7 × 10
refractive index units full scale (RIU mode).

Description
The ability to monitor refractive index and flow
cell temperature.
A countercurrent heat exchanger design and
temperature-controlled, low-volume cell permit
stable operation.
A configurable switch accommodates a maximum
+30 V and 1 A. The switch can trigger fraction
collectors and other external and it can actuate
based on time and refractive index threshold
criteria.
The ability to provide measured refractive index
signals to nano-RIU sensitivity.
Programmable, for purging the reference flow cell
before performing a measurement.

An 870-nm, long-life LED lamp.
A preconfigured diverter valve recycles solvent and
can be programmed to reduce solvent
consumption. The valve can be set to the waste or
recycle position via the console.
