Surveyor RI Plus Detector Hardware Manual
The Surveyor RI Plus Detector is a full-featured, low-maintenance, refractive index detector.
The detector is a bench-top unit for inclusion in the Surveyor Plus LC system. You control the
detector through an Ethernet link to the ChromQuest data system computer.
The Surveyor RI Plus Detector has the following features:
• An automatic intensity adjustment that compensates for the deterioration in sensitivity
due to flowcell contamination or reduced light levels
• A low volume (8 μL) flowcell, which reduces band broadening
• A solenoid valve that operates at half its rated voltage and a tungsten lamp that operates at
a reduced voltage to maximize component life
• LEDs (light emitting diodes) that keep you informed of power, communications, run,
and temperature status
• A dynamic operating range of 1.00 to 1.75 RIU, which makes the detector suitable for a
variety of applications
• Integrated instrument control from the ChromQuest data system, which provides
automated temperature control, a rise time filter, a purge function, an autozero function,
and built-in calibration procedures
The front panel of the Surveyor RI Plus Detector provides access to the flowcell connections.
Liquid enters the flowcell through the IN port and exits the flowcell through the OUT port.
The accessory kit for the Surveyor RI Plus Detector contains the following tubing
connections for the IN and OUT ports:
• The connection to the IN port consists of two stainless steel high-pressure fittings and
approximately 27 inches (69 cm) of 0.005-in ID × 1/16 in. OD stainless steel tubing.
• The connection for the OUT port consists of a five foot length of 0.060 in. ID × 1/16 in.
OD, Teflon tubing that has a piece of stainless steel tubing with a high-pressure fitting
inserted into one end.
