Improved High-end NEXT
NEXT for the next generation

Recommended configuration example
LC-9110II NEXT + JAIGEL-H Column (lD20mm x 2) + UV-Vis 4ch NEXT + RI-700NEXT
LC-9160II NEXT + JAIGEL-ODS Column + UV-Vis DAD NEXT + RI-700+ ClarityTM

Recycle with Non-diffusion (patent)
During extended recycling period, the recycled sample in the flow line may diffuse back into the solvent with the danger of contaminating the solvent reservoir. The N EXT series has non-diffusion device (patent) that prevents the sample from running back into the solvent line and damaging your sample,columns and detectors with back pressure.
Flash solvent function
Automatic flow line switching between the mobile phase and the column cleaning solvent is become reality.
Column cleaning after separation can be easily completed.

・Other features
Besides the recycle function is equipped, other various functions are equipped for your convenience, such as repeat injector, auto recycle, auto replay and fraction time auto adjusting.

・Large size LGD touch panel for easy operation
8.4 inch size touch panel screen enables easy and user-intuitive operation by simply touching icons at the fl ow channel diagram on the screen from start to collect.

Flow channel

・Auto cleanup function
Keeps the flow channels clean automatically. Solvent changeover when changing columns is also made much easily.

・Reliable solvent delivery peformance
Optimized serial double plunger pump dedicated for recycling is installed. Addition of digital flow rate compensation function enables reliable solvent delivery performance. The exact flow rate as setting value is guaranteed,regardless of column pressure.
・PC control function
With optional PC controling software Prepure-200 (or higher),it enables controlling LC-91N EXT remotely a nd collecting target peaks automatically with peak mode fraction.

・Injection overlap function
Enables to make second and subsequent injections without having to wait to complete previous operation.

Chromatogram data acquisition system

There are a few selection of software depends on your need and detector selection. UV-Vis 4ch NEXT works perfectly with JAI Scan and UV-Vis DAD NEXT works with ClarityTM. For other detectors,please choose from Prepure or JDS series.


Two different types of detectors are both smal enough to fit into NEXT series body. They can be installed together and perform detection simultaneously.
