Этилен технический. Определение следов полярных соединений. Подготовка проб конденсатов методом очистки при низких температурах
Название (англ.):
Ethylene for industrial use; determination of traces of polar compounds; preparation of condensate samples by low-temperature scrubbing technique
Описание (англ.):
Specifies a method of sampling by scrubbing at dry ice temperature (195 K). Permits the concentration of traces of all the less volatile polar compounds (water, alcohols, esters, acids, amines, etc.) in a small amount of liquid phase practically without anyinterference due to adsorption phenomena on the relatively small internal surfaces of the scrubbing absorber. This sampling technique permits the exact determination of all these polar compounds at contents greater than 0.01 mg/m
