Quantification of [Hb] was accomplished by scanning the sheets of chromatography paper
containing arrays of [micro]PADs on a portable flatbed scanner (CanoScan LiDE110, Canon USA) and then analyzing the images automatically with a custom-coded algorithm (MATLAB, The Math Works).
A hydrophobic material, such as wax or photoresist, is laid down into tiny canyons on chromatography paper
This note describes non-steady water flow experiments, conducted at 3 different constant temperatures during (a) absorption by initially relatively dry loam, (b) absorption of water by chromatography paper
, and (c) desorption of saturated swelling clay.
They did this by applying six samples of ink to a strip of chromatography paper
which was dipped in distilled water.

onto which a blood sample is placed.
