bottles are shipped in the same box as their corresponding sample submission form. Tape the box shut for shipping and ship as soon as possible after collection. The samples must be prepared for analysis within 7 days from the date of collection, and they must also keep their chilled temperature during transportation to the laboratory.

VOLATILE ORGANIC COMPOUNDS IN VARIOUS SAMPLE MATRICES USING EQUILIBRIUM HEADSPACE ANALYSIS 1.0 SCOPE AND APPLICATION 1.1 This method is a general purpose method for the preparation of volatile organic compounds (VOCs) in soil/sediment, solid waste, aqueous and water-miscible liquid samples for
− A sample of clean matrix (i.e., soil, water, etc.) is run to determine if the analytical equipment is contaminated. Surrogates − Surrogate compounds are compounds similar to the organic analytes of interest that are added to every sample at known concentrations in order to track the accuracy of the sample extraction and analysis.
prevent contamination. Sample vials/bottles should only be opened immediately before usage and capped immediately after. 4.2 Headspace in the sample bottles and exposure to the environment should be minimized to prevent vaporization and loss of volatile organic compounds. 4.3 Rubber can absorb volatile organic compounds. Use of that material is
Volatile Organic Compounds (VOCs) Overview When collecting samples for volatile organics analysis, the most critical aspect of the collection process is the prevention of headspace at the top of the sample in the container. The presence of headspace (i.e. air bubble) in the same container can compromise the integrity of the sample results.
