What is Chromatography?
Chromatography is a versatile analytical technique used to separate, identify, and quantify components in a mixture. It employs a stationary phase and a mobile phase to achieve separation based on different affinities of the components.
High Resolution: It provides high-resolution separation, allowing for detailed characterization of nanomaterials.
Versatility: Applicable to a wide range of nanomaterials, from
carbon-based nanomaterials to
metal nanoparticles.
Quantitative Analysis: Enables precise quantification of nanoparticle concentration and composition.
Purity Assessment: Critical for ensuring the purity of nanomaterials for biomedical and electronic applications.
Challenges in Chromatographic Analysis of Nanomaterials
Despite its advantages, chromatographic analysis of nanomaterials poses challenges: Complex Sample Preparation: Nanomaterials often require intricate sample preparation techniques to ensure compatibility with chromatographic systems.
Detector Sensitivity: High sensitivity detectors are essential to detect nanoparticles, especially at low concentrations.
Column Fouling: Nanoparticles can cause fouling of chromatographic columns, affecting the resolution and lifespan of the columns.
