HPLC Modules – Injection System

Internal and External Needle
High Injection Precision
Multi-Injection Mode
Lower Cross-Contamination
Unique Design

L-3320 Autosampler delivers high injection precision of 0.3% RSD, thanks to its high precision machining parts and advanced control algorithm. It also employs a design of multiple injection mode and changeable sampling loop, which extend linearity range and meet the need of more applications.

Features L-3320 Autosampler Injection System

Internal and External Needle

The build-in needle wash assembly has two washing positions for inter and outer needle wash separately, this double wash mechanism reduced the carryover significantly

High Injection Precision

Quantitative reproducibility of 3 compounds with different injection volume (RSD%) (n=6)

Multi-Injection Mode

The use of suction-type injection makes L-3320 simple, stable and reliable; with three injection modes including full loop, partial loop and micro pick-up mode for different requires

Lower Cross-Contamination

The patented sampling needle design and ultra precision inner and outer polishing technology,greatly reduced the carryover

Unique Design

All maintenance parts could be reached on the front side, which simplify the service procedure and lower maintenance cost

Patented Technologies

Strong R & D team and industry-leading technical strength, all products are self-developed, with a number of patented technologies

RIGOL L-3000 HPLC Systems were designed in accordance with UHPLC standard, with an outstanding operating pressure limit 9,000 psi, that’s the highest pressure range compare to similar HPLC system.

The L-3100 Series Solvent Organizer configured in L-3000 HPLC System,can be equipped with high efficiency degasser,which will removethe remaining gas dissolved in the mobile phaseand make the pump operation more stabilized. And the standard on-line washing system modulecanreal-time clean the salt crystallization on plunger rod and sealing ring to prolong the service life.

L-3200 Series High Pressure Pump could reach 9000psi (62MPa) working pressure with the flow rate up to 10mL/min. This high performance extend the application field from normal HPLC to Fast HPLC. L-3200 serial high pressure pump provides isocratic, binary and quaternary model base on request: Isocratic pump for regular QA/QC usage, Binary pump for high-throughput & fast analysis, Quaternary pump for pharmaceutical, food and environmental test.

L-3320 Autosampler delivers high injection precision of 0.3% RSD, thanks to its high precision machining parts and advanced control algorithm. It also employs a design of multiple injection mode and changeable sampling loop, which extend linearity range and meet the need of more applications.

Semiconductor temperature control technology is used in L-3400 Column Ovento ensure the stable temperature raising and precise temperature control. L-3400 Column Oven is equipped in L-3000 HPLC system to minimize the environmental impact and results in better results.

L-3500 UV-Vis Detector uses a unique high-speed signal processing technology, a unique light path design and a patented circuit and structure design to achieve ultra-high sampling rates of 100Hz with a wider linearity range and higher signal to noise ratio.
