Stop flow spectrometerAlso known as a stationary flow spectrophotometer or a cutoff spectrophotometer, it is an advanced analytical instrument used to study the mechanism of very rapid reactions in solution systems.
Main components:
Hybrid system: used to mix two reactants at an extremely fast speed, usually using jet or pressure driven methods.
Flow system: A pipeline network that transports reactants and reagents to a mixing system and captures reaction products.
Light source: Generate short pulse light for exciting the reaction mixture.
Detector: detects the light signal generated during the reaction process.
Data acquisition system: converts detector signals into digital signals and processes them to obtain reaction kinetics information.
Technical characteristics:
Fast mixing: It can achieve fast and uniform mixing in a very short time, ensuring the instantaneous nature of the reaction.
Accurate triggering: Synchronize with mixed events to trigger light pulses, ensuring the synchronization of light signals and chemical reactions.
High sensitivity detection: capable of detecting weak light signals generated during the reaction process, improving measurement accuracy.
Fast data collection: Collect and process data at a high sampling rate to ensure real-time and complete data.
In addition, stop flow spectrometers are widely used in dynamic studies of intermolecular interactions, such as protein-protein and protein ligand binding, electron transfer, various synergistic effects, and other chemical reactions.
