MCH-022 Solved Assignment 2026-27 Overview

The MCH-022 Solved Assignment 2026-27 in English covers important separation and analytical spectroscopy techniques used in chemistry.

The first section deals with metal-ion extraction using crown ethers and masking agents. It then moves to liquid-solid chromatography, adsorbents, paper chromatography and thin-layer chromatography.

The assignment also covers gas chromatography, HPLC instrumentation, synthetic ion exchangers and size exclusion chromatography. These topics provide useful understanding of modern separation techniques.

Membrane separation, water treatment, table-salt production and capillary electrochromatography also form part of the assignment.

The spectroscopy section covers UV-Visible spectroscopy, FTIR, fluorimetry, phosphorimetry, atomic emission spectroscopy and FT-NMR.

Finally, the assignment discusses DEPT in ¹³C NMR, 2D NMR, mass spectrometry, GC-MS and LC-MS.
