•
Single channel/additional channel to monitor temperature – Monitors refractive
index and either the detector oven or column heater module temperatures.
•
Full diagnostic capability – Supports built-in diagnostic tools to optimize
functionality and performance.
•
Thermal stability
– The 2414 RI detector uses a countercurrent heat exchanger
design and temperature-controlled cell for stable operation and fast warmup
and reequilibration times.
•
Ethernet support – Allows the 2414 RI detector to operate as a component of an
HPLC system controlled by a chromatography data software, such as Empower
®
software and MassLynx
®
software, using Ethernet communications.
•
IEEE-488 support – Allows the 2414 RI detector to operate as a component of
an HPLC system controlled by chromatography data software or an Alliance
e2695 separations module using IEEE-488 communications.
•
Single, programmable contact closure output – The 2414 RI detector has a
configurable switch, which can accommodate a m30 V and 1 A. The
switch (SW1) can trigger fraction collectors and other external devices, as well
as activate based on time and refractive index threshold criteria.
•
Refractive index units – In RIU mode, the 2414 RI detector provides measured
refractive index signals to nano-RIU sensitivity.
•
Purge mode – Before performing a measurement, the 2414 RI detector can be
programmed automatically or by using the front panel keypad to purge the
reference flow cell.
•
Programmable autozero – At the beginning of an injection, the 2414 RI detector
can be programmed to autozero the signal output immediately or after a
programmable time delay of up to 30 seconds.
•
Column heater module control – The 2414 RI detector can control a single
Waters column heater module.
•
Long-life LED – The 2414 RI detector is equipped with an 870-nm, long-life LED.
•
Recycle valve – A preconfigured diverter valve used to recycle solvent during
equilibration to reduce solvent consumption.
1.3.3 Operation modes
The 2414 RI detector operates as a single-channel detector, but can be configured to
operate in one of two modes to acquire refractive index signal data: RIU mode and
410 emulation mode. Additionally, the detector can monitor temperature as an
auxiliary channel.
1.3.3.1
RIU mode
RIU mode is the default operating mode for the 2414 RI detector which monitors a
single channel using micro-refractive index units (µRIUs). Note, however, that RIU
mode is not compatible with legacy data systems or controllers.
Methods and timed event programming are available only when the detector is
configured in RIU mode.
You can configure several additional parameters when using the detector in RIU
mode:
