Thermo Fisher Ultimate 3000 UPLC Ultra High Performance Liquid Chromatography System
The Thermo Fisher Ultimate 3000 UPLC Ultra High Performance Liquid Chromatography System is a modular liquid chromatography system that combines high efficiency, precision, and flexibility. This instrument is based on the "UHPLC+" design concept, seamlessly connecting the entire flow rate range of nanoliter liquid phase, conventional liquid phase, and fast liquid phase (UHPLC), aiming to provide comprehensive solutions for complex sample analysis in fields such as pharmaceuticals, biotechnology, food, environment, and life sciences. Its core advantage lies in achieving a smooth transition from conventional analysis to ultra efficient separation through modular design, while maintaining ultra-high stability and data reproducibility.
The instrument adopts advanced SmartFlow technology to ensure precise control of flow rate, thereby ensuring the stability of retention time and the reliability of peak integration. The system is equipped with an online vacuum degassing machine, which can effectively eliminate the interference of bubbles in the mobile phase, and the automatic plunger cleaning function significantly extends the service life of the pump, especially when dealing with high salt concentration mobile phases.
The instrument supports a variety of detector configurations, including ultraviolet/visible (VWD/DAD), fluorescence (FLD), electrochemistry (ECD) and electric spray detector (CAD), which can meet the different requirements from conventional qualitative and quantitative analysis to trace analysis. In addition, its unique dual ternary gradient pump (DGLC) design supports advanced applications such as online solid-phase extraction (SPE) and two-dimensional liquid chromatography (2D-LC), greatly enhancing the separation capability and analytical flux of complex samples.
In addition, the Chromeleon chameleon chromatography data system that comes with the instrument provides an intuitive operating interface and powerful data processing capabilities, supporting automated management of the entire process from instrument control to report generation.
In terms of application fields, this instrument is widely used in ADME screening in drug development, quality control of biological therapy drugs, detection of pesticide residues and additives in food, analysis of polycyclic aromatic hydrocarbons in the environment, and proteomics and metabolomics research in life sciences due to its wide flow rate range (from nano to semi preparation grade) and strong pressure resistance.
