1. Product information
The AZURA® Detector RID 2.1L / RID 2.1L HighFlow
1
is a sensitive and
competitively priced differential refractometer which is suitable for
detecting compounds with little or no UV activity such as alcohols, sugars,
lipids or polymers in high concentrations.
The device is a member of the AZURA L product line and shares a num-
ber of common features.
The front cover serves as a protection for the detector and its users,
but can also be removed.
The detector is a sturdy device due to its large footprint and low center
of gravity.
The leak tray on the front collects leaking fluids and protects the com-
ponents from possible damage.
The LEDs indicate the device status. This tells the user whether the
detector is working properly or whether an error has occurred.
On the rear side you will find the supply connection and further con-
nections to control the device.
The device name is above the serial number on the front. A white stick-
er on the back gives information about the manufacturer (name and
address), the product number and the specifications of the supply
connection.
Note:
At the time of delivery, the detector is filled with ethanol.

Intended use
Note:
Only use the device for applications that fall within the range of
the intended use. Otherwise, the protective and safety equipment of the
device could fail.
Detection via refractive index is very suitable for analytical HPLC
(High Performance Liquid Chromatography), GPC (Gel Permeation
Chromatography) and SEC (Size Exclusion Chromatography).
RI detectors are extremely versatile, but the detection is made with
lower sensitivity as with other detection methods. RI detectors are not
suitable for gradient chromatography, because they react very sensitive
to changes in eluent composition. In addition, RI detectors are very
dependent from temperature and pressure, and unstable conditions
cause base line instability. In some cases, positive and negative peaks
may occur in a single analysis.
The detector is designed for research and may be not suitable for
diagnostic purposes.
