ASTM D7482 Standard Practice for Sampling, Storage, and Handling of Hydrocarbons for Mercury Analysis
6. Apparatus
6.1 Clear or Amber Borosilicate Glass, 40-mL or less in volume; pre-cleaned by acid-washing; with PTFE (polytetrafluoroethylene)-lined septum caps. These are commonly referred to as VOA vials and are used for many water samples using EPA methods.
6.1.1 The use of 30-mL or smaller VOA vials may allow shipment of multiple sample vials as "excepted quantities" under IATA (International Air Transport Association) regulations. Determine specific shipping requirements with the appropriate knowledgeable personnel.
6.2 Alternate Containers - Quartz. Epoxy-lined, tin-lined, or steel cans for direct or sub-sample may not be acceptable because, in some cases, these types of containers show a significant depletion of mercury (see 9.1 and 9.2).
6.2.1 Tin-lined steel cans, direct or sub-sample, are not acceptable.
6.3 Chain of Custody Forms.
6.4 Permanent Marking Pens.
6.5 Resealable Bags - Clear, plastic, 1-L capacity.
