The limited accessibility of stationary phase pore volume for the polymer molecules results in shorter elution times for high-molecular-mass species.
42.
The reaction with 99m TcO 4 & minus; takes place directly after elution from the generator column and shortly before its intended use.
43.
A chloroform-ethanol gradient elution High-performance liquid chromatography system was used to extract the iridoid glycosides campenoside and 5-hydroxycampenoside.
44.
The stronger the interactions between the polar analyte and the polar stationary phase ( relative to the mobile phase ) the longer the elution time.
45.
Gradient elution uses this effect by automatically reducing the polarity and the surface tension of the aqueous mobile phase during the course of the analysis.
46.
"' TREF : "'performs the TREF technique ( Temperature Rising Elution Fractionation ) for the characterization of CCD in Polyolefins.
47.
Ideal elutions occurred at 35 �C, but decreasing the temperature to 10 �C or raising it to 50 �C caused faster elutions either way.

49.
An elution with a low pH buffer or a more gentle, high salt elution buffer is then used to recover purified antibody from the support.
