This essay introduces a method of determining the dimethylacetamide concentration by gas chromatography in the dialyzer. The clinical dialysis process is simulated. The capillary chromingraphic method is used with the peak area and the external standard method, Optimizing testing conditions of gas chromatography. Therefore, This method shows good sensitivity and good repeatability.

UI	MeSH Term	Description	Entries
D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.

D003956	Dialysis	A process of selective diffusion through a membrane. It is usually used to separate low-molecular-weight solutes which diffuse through the membrane from the colloidal and high-molecular-weight solutes which do not.
