Chromatographic techniques that are based on the principle of differential adsorption are:
- Column chromatography (A)
- Thin layer chromatography (B)
Both these techniques operate on the principle of differential adsorption, where components of a mixture are adsorbed to different extents on a stationary phase and thus separate during the process.
The Correct Answer is: A & B only
Let a line passing through the point $ (4,1,0) $ intersect the line $ L_1: \frac{x - 1}{2} = \frac{y - 2}{3} = \frac{z - 3}{4} $ at the point $ A(\alpha, \beta, \gamma) $ and the line $ L_2: x - 6 = y = -z + 4 $ at the point $ B(a, b, c) $. Then $ \begin{vmatrix} 1 & 0 & 1 \\ \alpha & \beta & \gamma \\ a & b & c \end{vmatrix} \text{ is equal to} $
