Fraction collectors are essential and central tools in laboratories involved in separation processes based on chromatography (such as HPLC, FPLC, GC) or filtration. They enable controlled, automated, and precise collection of fractions from the outflow stream of a separation column, according to predefined parameters. This instrument is critical for isolating specific components from complex mixtures for subsequent analysis, characterization, or further use.
The operating principle of a fraction collector is based on automatically diverting the eluent exiting the separation column into different collection vessels in a sequential manner. The transition between collection vessels is performed according to criteria defined by the user, such as elapsed time, collected volume, or most commonly – peak detection using a detector connected in series with the chromatography system (for example, a UV/Vis detector). The ability to accurately collect the desired peak allows for efficient isolation of the compound of interest at a high degree of purity.
Modern fraction collectors offer great flexibility in terms of collection vessels (test tubes, vials, microplates), compatibility with various volumes and flow rates, and seamless integration with chromatography system control software. The automation provided by fraction collectors dramatically reduces the need for manual monitoring, saves valuable time, minimizes human error, and ensures high reproducibility and reliability of the collection process, which are critical in research and quality control. They provide precise, unattended collection, allowing researchers to focus on other tasks while maintaining the integrity of their valuable samples.
The use of fraction collectors is widespread and diverse across various laboratories:
