Question:

Suppose that an HPLC column produces Gaussian peaks. The detector measures absorbance at 254 nm. A sample containing equal moles of compounds A and B was injected into the column. Compound A (ε254] = 2.26 × 104M-1 cm-1) has a height h = 128 mm and a halfwidth w1/2 = 10.1 mm. Compound B (ε254 = 1.68 × 104 M-1 cm-1) has w1/2 = 7.6 mm. What is the height of peak B in millimeters?
