Ultra High-Performance Liquid Chromatography System LZ-UHPLC-A100 is a stacked, modular UHPLC that separates and measures the components of complex liquid samples. A linear motor quaternary pump drives the mobile phase up to 70 MPa, a autosampler loads samples, and a column compartment holds the temperature steady. A PDA detector and an ELSD detector read the eluting peaks. It offers 0.001 to 10 mL/min flow. Labs use it for pharmaceutical, food and chemical analysis.
