Question

How many theoretical plates produce a chromatography peak eluating at 12.83 minutes with a width at half-height of 8.7s?
B) the length of the column is 15.8cm. Find the plate height. How many theoretical plates produce a chromatography peak eluating at 12.83 minutes with a width at half-height of 8.7s?

B) the length of the column is 15.8cm. Find the plate height.

Explanation / Answer

Plate number(N) = 16(tr /w)2 (W=peak wedth 8.7 cm)

= 16(12.83 /8.7)2

  =16 x2.1609= 34.57

Plate hight = L / N = 15.8 / 34.57 = 0.457 cm
