| Description | The LC-4500 Compact HPLC System is so flexible that it can be used for a wide range of applications in academic research, teaching, or QA/QC.
The extremely compact stackable design requires only 6 inches (15 cm) of bench space, and can be easily fit into most fume cabinets where space is a premiumThe LC-4500 Compact HPLC System is so flexible that it can be used for a wide range of applications in academic research, teaching, or QA/QC.
The extremely compact stackable design requires only 6 inches (15 cm) of bench space, and can be easily fit into most fume cabinets where space is a premium.
The individual pump (PU-4580), detector (UV-4570), and autosampler (AS-4550) modules each have an option for keypad control, external control by RS232, or simple contact closure, so that they can be readily incorporated into other systems for both chromatography and non-chromatography applications.
The system employs an asymmetric twin-piston solvent delivery system SSQD (Slow Suction, Quick Delivery) which provides significantly better flow and pressure profiles than the commonly used conventional twin-piston reciprocating design.
In the LC-4500 model, SSQD has been re-developed, with a new solvent delivery mechanism offering the highest stability in solvent delivery across the entire analytical flow rate range.
Features: - Compact - LC-4500 compact module (width: 15 cm) makes effective use of lab space.
- Flexible - PU-4580 enables to configure the various solvent delivery system, and AS-4550 can provide the various sample injection method. Therefore, these modules achieve to build the ideal system. Combination with existing LC-4000 modules can provides wider application.
- User-friendly - For those users who require front-panel control, the LC-4500 model retains the popular keypad and display (with a backlit LED display as standard). Keypad control can still be configured for convenient override when under PC control.

The system can be used for multiple sample library purification or individual component large-scale purification, with sample injection either using a preparative autosampler or syringe basedThe preparative SFC system is used for large scale purification using columns with IDs of 10, 20, and 30 mm. The system can be used for multiple sample library purification or individual component large-scale purification, with sample injection either using a preparative autosampler or syringe based large volume injector. Fraction collection can be triggered based on time, threshold or slope from up to 4 different detector signals including PDA, UV, CD, and/or MS. The flexible fraction layout includes open-bed fraction collection for a larger number of fractions for multiple samples or valve based with up to 8 fractions for repeated injections producing large fraction volumes. ChromNAV provides complete integrated control for flow rate, temperature, sample injection and fractionation. The SFC-4000 Preparative systems can be used for purifications using 10mm, 20mm or 30mm ID columns. The flexible configuration can be easily changed to suit a basic single column/single detector system or a multi-column/multi-detector system. Fraction collection options range from simple time-based 6 or 8 fractions to sophisticated threshold based open-bed fraction collection for up to 80 fractions. System control provides simple acquisition of chromatograms, automated data analysis, manual and automated fraction collection and a method scouting module for fast solvent and column screening....
