Objectives - modern liquid Chromatographic techniques have undergone a paradigm shift, driven by Focused on improving separation efficiency, resolution and sensitivity. HPLC, UPLC, UHPLC, HILIC, LC-MS represent-key methodologies", in this evolution. Methods: Method have advanced with the adoption of UHPLC, UPLC Featuring smaller particle sizes that enables Faster analyses without compromising resolution. Integration with Lc-Ms, HPLC further enhances capabilities by providing simultaneous identification and quantification. Results: These techniques showcase significant improvements, UHPLC'S UPLC's higher pressure Capabilities contribute to enhanced resolution, While HPLC, HILIC, Lc-Ms extends analytical scope by offering structural information. The Combined Strengths of those techniques have transformative effects across Scientific disciplines. Conclusion - Modern liquid chromatographic techniques fulfil objectives through techniques fulfil refined methodologies, yielding results marked by improved performance the Continuous evolution of these techniques promised further strides in analytical capabilities
