Disconnect the pump from the charger before calibration. Use the same specific type of sample media in line that will be used for sampling in the field (e.g., filter, sorbent tube); but do not use the actual media used for calibration for field sampling. Where more than one pump will be used in the field, label the pumps to avoid mix-up.

Allotropy - Wikipedia

Allotropy or allotropism (from Ancient Greek ἄλλος (allos), meaning ''other'', and τρόπος (tropos), meaning ''manner, form'') is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of the elements.

ion Names and Formulas Help - Mark Bishop

ion Names and Formulas Help Metallic atoms hold some of their electrons relatively loosely, and as a result, they tend to lose electrons and form ions. In contrast, nonmetallic atoms attract electrons more strongly than metallic atoms, and so nonmetals tend to gain electrons and form anions.

Displacement reactions between metals and their salts

Some metals are more reactive than others. In this experiment, a strip of metal is added to a solution of another metal. A more reactive metal displaces a less reactive metal from its compound. In carrying out the experiment, students investigate competition reactions of metals and arrive at a reactivity series of the four metals they use.
