Раствор калия гидрофосфата. Подвижн

Раствор калия гидрофосфата.
Подвижная фаза: смешивают метанол и раствор калия гидрофосфата в соотношении 3:1, фильтруют полученный раствор через мембранный фильтр с диаметром пор 0,2 мкм и дегазируют. Корректируют соотношение объемов для получения необходимого разрешения при необходимости.
Раствор внутреннего стандартаЖ около 3,5 мг (точная навеска) стандартного образца тестостерона пропионата переносят в мерную колбу вместимостью 50 мл, доводят абсолютным спиртом до метки и перемешивают (концентрация раствора приблизительно 0.07 мг/мл).

Solution of potassium hydrogen. Mobile phase: methanol and mixed solution of potassium hydrogen in the ratio 3:1, the resulting solution is filtered through a membrane filter with a pore diameter of 0.2 μm and degassed. Adjust the volume ratio to obtain the required permission when necessary. Internal solution standartaŽ about 3.5 mg (accurate mounting) standard testosterone propionate shift in measuring flask with a capacity of 50 ml of absolute alcohol, lead up to the mark and mix (the concentration of the solution is approximately 0.07 mg/ml).
