CHRONECT Extract Collector | Alias™
Autosampler, Fraction Collector

Multipurpose sample handling device

1. as a fraction collector

ALIAS™ is a multipurpose sample handling device that has been installed in hundreds of labs and is known for its ease of use, flexibility, and rugged reliability.In the CHRONECT “Sytems,” the ALIAS is used as a fraction collector for applications requiring preservation of key analytes and/or products of upstream separations, under complete and integrated control of the CHRONOS software.

2. as an autosampler

ALIAS™ is a generic autosampler for HPLC and LC-MS using state-of-the-art injection technology with fast injection and wash cycles. Designed to fit any system for any application. Multi-solvent needle wash virtually eliminates carry-over. ALIAS™ handles well plates and sample vials, either open or sealed, and provides true 4°C sample cooling. Its compact, stackable design and unrivalled performance make the ALIAS™ autosampler the best fit for your (U)HPLC system.

ALIAS™ UHPLC | ALIAS™ is also available as a UHPLC compatible version permitting injection into UHPLC systems operated at pressures as high as 18,000 PSI. A special injection routine has been developed to eliminate influence of sample loop decompression on injection performance. The UHPLC version can also be equipped with sample cooling.

ALIAS™ Prep LC | A special modification for large volume injections turns the ALIAS™ into a perfect injector for your preparative LC system. The ALIAS™ Prep version holds 24 vials of 10 mL and uses a 2.5 mL syringe. Needles, tubing and sample loop have larger capacity and allow rapid injection of sample volumes up to 10 mL.
