Microplastics in water: sampling, principles & spectroscopy
ISO 24187 frames analysis principles, ISO 5667-27 guides water sampling and ISO 16094-2 covers vibrational spectroscopy for water with low suspended solids. Parts 1, 3 and 4 of ISO 16094 remain drafts and are not final methods.
Sample considerations
- ISO 24187: Environmental compartment, particle size range, polymer targets and reporting units
- ISO 16094-2: Water matrix, suspended-solids level, filtration, instrument mode and size range
- ISO 5667-27: Water body, sampling objective, contamination controls and preservation
