Unique flow cell and optical system - Optimum for high-sensitivity analysis!
List of Sales Representatives Technical Materials
Photodiode Array Detector
Changing the History of High-sensitivity Analysis
Compact design (H20 x W35 x D43 cm)
Light weight (15 kg)
Flow Cell with Innovative Structure
50-mm optical path makes the sensitivity five times greater (cell volume: 10 µL).
Structure consisting of a cell covered with PEEK resin prevents irregular reflection.
High-sensitivity Analysis over a Wide Range
Simultaneous use of a tungsten lamp and a deuterium lamp
Glass Optical Fiber
Conventional slit structure suppresses stray light and optical fiber minimizes diffusion.
Wavelength Calibration and GLP
. Easy wavelength calibration by PC on-screen instructions
. GLP support: Database management of all information utilizing EZChrom3.1
 High-sensitivity LC-PDA Analysis
. NANOSPACE SI-2 optimized for semi-microcolumn produces sharp peak with minimum sample diffusion.
. Optimum for high-sensitivity analysis with less carryover thanks to the use of inert materials for flow paths and various rinsing functions.
Analysis of Bisphenol A
Despite the 10 ÁL cell volume, sharp peaks are obtained due to the flow path that is designed for operation with semi-microcolumns.
