Choose the correct answer from the options given below:
Matching Analytical Techniques with Components
This question requires matching analytical techniques from LIST-I with their associated components or principles in LIST-II.
List I Analysis
- A. HPLC (High-Performance Liquid Chromatography): This technique relies on a high-pressure system to move the mobile phase through the column. Therefore, it is correctly matched with II. Pump.
- B. AAS (Atomic Absorption Spectroscopy): AAS requires the sample to be vaporized or atomized before measurement. The term 'Automizer' likely refers to an Atomizer (e.g., flame or graphite furnace). This matches with IV. Automizer.
- C. CZE (Capillary Zone Electrophoresis): This separation technique is based on the differential migration of analytes in an electric field, influenced by their charge and size relative to the buffer, which relates to III. Zeta potential.
- D. HPTLC (High-Performance Thin-Layer Chromatography): Unlike HPLC, HPTLC uses a flat surface (plate) as the stationary phase. This corresponds to I. Planar surface.
Correct Matching
Based on the analysis of each technique:
- A matches with II
- B matches with IV
- C matches with III
- D matches with I
Therefore, the correct combination is A-II, B-IV, C-III, D-I.
