These instructions are for samples taken for environmental testing.
The sample sizes, preservation procedures, holding times and conditions for air, aqueous and solid samples are recommendations only.
Base your decision on the nature of the sample, the intended use of the data and the data quality objectives. For example, you can use alternative storage conditions if the analyte stability within a matrix can be demonstrated and data quality objectives are not compromised.
In a given sample, the analyte requiring the most preservation treatment as well as the shortest holding time should dictate the preservation treatment of the overall sample.
Each sample type has different recommendations for storage conditions needed to preserve the sample. See our recommended preservation procedures, holding times and conditions for:
Certain substances must be labelled under the Globally Harmonized System (GHS) of classification and labelling.
