The HPLC (High-Performance Liquid Chromatography) solvent reservoir area is where the solvents used in HPLC systems are stored and ready to be fed to the pump. This area can be designed to allow multiple solvents to be used together and is usually made of glass or special containers. The solvent reservoir is vital for the efficient and continuous operation of the HPLC system.
What Does It Do?
Solvent Feed: In HPLC, it delivers the mobile phase (solvent) required for the separation of samples to the system in a steady stream.
Uninterrupted Flow: Provides a constant flow of solvent to the high-precision pump system, thus preventing interruption of the analysis process.
Preparation of Mixtures: Used for mixing different solvents in the right proportions and adjusting the composition of the mobile phase.
Why Should We Use It?
Provides Steady Flow: In the HPLC system, a continuous and steady delivery of the mobile phase to the pump is essential for the accuracy and reproducibility of chromatographic analysis.
Correct Preparation of Solvent Mixtures: If more than one solvent needs to be combined, the solvent reservoir ensures that these mixtures are delivered to the system in a constant and accurate ratio.
Air Entry Prevented: The solvent reservoir is usually equipped with caps to prevent air ingress. This prevents air bubbles from forming during analysis, which can damage the pump and detector.
Cleanliness and Stability: Solvent reservoirs are often equipped with particulate filters and inert coating materials to maintain the purity and stability of the solvents.
The HPLC solvent reservoir is a critical component to ensure correct system operation and reliable analysis results.
