Field SPE samples usually are extracted after most other onsite activities are completed or by a third team member because equipment setup, sample extraction, and equipment cleaning can be quite time consuming. Fill the bottle with raw sample directly from the sampling or splitting device. Leave a small headspace in the bottle. Pour, discharge, or pump the raw sample directly into the sample bottle. Fill to the shoulder of the bottle, leaving a small headspace.
Field rinse the bottle and fill with raw sample.
