| Abstract: | This paper discusses the various conditions for separating and determining trace amniotic fluid cat-echolamine by using reversed-phase high-performance liquid chromatography with electrochemical detector. Three main catceholamines have separated within 8 min, linear range of calibration curve is 0.15 - 12.00 nmol/L for norepinephrine 0.13-6. 50 nmol/L for epinephrine,0.15-12. 50 nmol/L for depamine. The relative standard deviation is less than 2.2%. |
