Lingkup HPLC

HPLC 5

Efisiensi Kolom

Efek partikel size fase diam

HPLC 6

Pelebaran pita ekstra kolom

- Terjadi saat solute melewati sistem injeksi, detektor dan pipa/tubing konektor

- Pelebaran terjadi karena perbedaan laju alir antara fase gerak yang berada di pusat dan di tepi

Hex =r2µ24DM

Hex = efek ekstra kolom

r = jari-jari tubing

µ = laju alir linear (cm/s)

DM = koefisien difusi solute dlm fase gerak
