We have given considerable experimental details of the practicality and usefulness of chloroaluminium phthalocyanines (ClAlPc) as amperometric gas sensors, and have emphasised the care that must be taken in a real situation to ensure reliable results especially when detecting critical concentrations (sometimes in parts per billion) of toxic or highly inflammable gases.
