Chromatography: And Analogous Differential Migration Methods

Recent developments towards a unified theory for separation science (Minireview)

“…(15) respectively. Equation (16) makes no assumptions as to the mechanism which gives rise to the movement of the analytes and is therefore generally applicable. Equation (16) also emphasizes that resolution is maximized when the ratio of the migration velocities is largest, not the difference of the two velocities.…”

Paper Electrophoresis in the Identification of Writing Inks. Comparison with Horizontal Paper Chromatography

“…Paper electrophoresis depends on an entirely different principle (8,9,10,11). Materials which are ionic or can be rendered ionic by adjustment of the environment will move in an electric field toward the electrode of opposite sign.…”

Horizontal Paper Chromatography in the Identification of Ball Point Pen Inks

“…Its bibliography is now so extensive (2,3,4,5) that few people can hope to read even the more important papers in the field. Only within the last two or three years have publications appeared (6,7,8,9) describing its application to the field of ink identification.…”
