About Test kits for water analysis

This unit steps outside the laboratory to look at some examples of analytical procedures being carried out in the field using commercial test kits. These quick tests provide results on-site, extending the options available to analysts. The methods used are chemical or microbiological in nature, made portable by microelectronics. By the end of this unit you should be able to: Appreciate the range of test kits available for determining some of the key parameters defining water quality on-site. Appreciate the criteria involved in obtaining a representative sample and carrying out fit-for-purpose measurements. Understand the chemical principles underpinning portable colourimetric, titrimetric and non-photometric instrumental test kits and the technical considerations which make portability possible. Understand the operation of a portable bioluminescence unit for ATP testing. Recognise the health and safety requirements of carrying out field measurements.
