It is suggested that this method could be termed transient “pseudosotachophoresis” (pseudoITP).,第十三頁,共二十一頁。,Because of their low conductivity, these water miscible organic solvents provide the high field strength necessary for band sharpening similar to that provided by the terminating ion. Salts, when
