Introduction

L-3000 binary  autosampling HPLC System is designed in accordance with UHPLC standard: with an outstanding operating pressure limit 9,000 psi;  high-precision injector drive-unit provides excellent accuracy and linearity.

This product owns independent intellectual property rights, all of the key units/modules are of autonomous design and manufacturing. Performance of the entire system reaches advanced world level.

Features:

1,Up to 9000PSI operational pressure. Higher working pressure extends the dynamic range in the application of chromatographic analysis, and improves the durability and reliability of the entire system.

2,Up to 2.5 AU linear range of the detector, allows accurate analysis for widely varying sample concentrations, either with high concentrated substance(s) or trace component(s).

3,Up to 100Hz data sampling rate, allows sharper peak(s) detection and enables ultra fast analysis.

4,As low as 5x10-9 g/mL detection limit, creating higher sensitivity with lower noise floor.

5,Proprietary automatic solvent-compressibility compensation and pulsation dampening technologies enable excellent analysis reproducibility.

6,User-friendly HPLC workstation, complies with the FDA 21 CFR Part 11, GLP, GMP regulations.

L-3000 Accessories & Optional Parts

Chromatographic column is the key part for resolution in HPLC System. A column with properties of high column-effeciency, good selectivity and fast resolution is enssential to the establishment of a good HPLC method. Endusers can select columns according to their different analytical demands, while RIGOL can provide the following columns:
