Optical Detectors
Chemiluminescence – Detection of optically active compounds
 |
Equipped with a low dispersion flow cell
|
|
Sensitive detection of lipids, nucleotides, nitrogen oxides (NOx) and
catecholamines
|
Highly Sensitive Detection: Background noise becomes extremely low because substance excitation is performed by a chemical reaction rather than an excitation light source. This enables a high degree of sensitivity.

Refractive Index – High sensitivity detection with a prism flow cell
|
|
Analytical and semi-preparative flow rate to 50 ml/min
|
|
|
Low noise, stable baseline
|
|
|
Time programming for sensitivity range and reference cell purging
|
|
|
Temperature stabilization from 10ºC above ambient to 45ºC
|
Molecular Weight Distribution: The RI-2031 can be used for calculating molecular weight distribution because peak size, according to an RI detector, is nearly proportional to concentration.

PU-2089 Quaternary low-pressure gradient pump
|
|
Slow suction, quick delivery (SSQD) pumping method for reliable,
accurate and stable solvent delivery
|
|
|
Built-in proportioning valve and degasser for low-pressure mixing of up to
four solvents without having to reconfigure the system

Flow range 1 µL/min to 10 mL/min
|
|
|
Less than 0.1% flow rate precision at 0.2 ~ 5.0 mL/min
|
The use of a new high-precision valve for low-pressure gradients improves gradient resolution and enables more accurate gradient analysis.
