A free booklet is available which describes techniques for measuring pH,
ions, and dissolved oxygen in very small samples down to 20 microliters.
Sample vessels which can be routinely measured included 96 well plates,
microcentrifuge tubes, NMR tubes, serum cups, and capillary tubes. Ions
which can be measured include chloride, sodium, potassium, and cyanide.
All probes require only a pH meter for measurement. For further details
