|---|---|
| (A) Laser source | (I) Electron Capture Detector |
| (B) Thermometric titration | (II) Polarography |
| (C) Gelatin | (III) Heat of reaction |
| (D) Gas-liquid chromatography | (IV) Spectrofluorimetry |
(a)Laser source (I) Electron Capture Detector
(b)Thermometric titration (II) Polarography
(c)Gelatin (III) Heat of reaction
(d)Gas-liquid chromatography (IV) Spectrofluorimetry
Answer
Answer: A ✓ checked by 4AB · confidence high
Answer: A–IV, B–III, C–II, D–I.
Explanation
Answer: A–IV, B–III, C–II, D–I — Lasers are excitation sources in spectrofluorimetry. A thermometric titration follows the heat of reaction. Gelatin suppresses polarographic maxima. The electron-capture detector is used in GLC.
