Question

A chromatogram gives an ideal Gaussian peak with a retention time of 8.20 min and a peak width at half height of 0.16 min. If the column is 10.2 cm long then what is the plate height in mm (round your answer to one significant figure and don't include units in your answer)?

GIve me the answer in a correct one significant figure

Answer 1

peak with a Ans: - Given that A chromatogram gives an ideal Gaussian reaction time = 8:20 min and peak width the halt height = 0.16 min if the column = 10.2cm long No. of plates on column (N) = 5. 5.55tx² - (W112 = 5.55 x 18.20 min) (0.16) 373,182 0.0256 = column 14577.42 length) plate height(H) - 10. 2cm = 0.0006997 cm 14577.42 .: = 6.9971x1018 cm Plate height (mm): 0.069971 mm
