Column performance control
Check the performance of the column using the following procedure:
Sample: 100 ¦Ìl 0.5% acetone (5mg/ml)
Eluent: buffer solution or distilled H2O
Flow rate: 0.75 ml/min, room temperature
Detection: 280 nm
Column efficiency, expressed as the number of theoretical plates per meter, N/m, is
calculated using the following equation:
N/m = 5.54 ¡Á (vr / w½ ƽ·½ ¡Á (1000/L)
where
N/m = number of theoretical plates/meter
vr = peak elution distance (m)
w½ = peak width at half peak height (m)
L = bed height (m)
