Sodium Cation Was Separated from a Mixture of Cations Via

question 3

Short Answer

Sodium cation was separated from a mixture of cations via capillary electrophoresis,with negative detection.The instrument is equipped with a capillary 50 cm in length,with 45 cm to the detector.The separation took place under 30 kV with the neutral marker reaching the detector after 200 seconds.The retention time for Na⁺ is 85 seconds.Calculate the number of theoretical plates for the Na⁺ peak.The diffusion coefficient for Na⁺ in water is 1.0 × 10⁻⁹ m²/s.
