Aijiren Tech™ Premium Pack Amber Glass Vials with Closed-Top Cap are Certified to meet EPA Performance Based Specifications for Volatile Organic Analysis, and are recommended for light sensitic analytes—available in 20mL or 40mL sizes. Amber vial designed for volatile organic analysis (VOA); recommended for light sensitive analytes.
Soil sample preservation for volatile organic compound analysis generally requires short sample holding times or preservation of the sample’s chemical constituents with sodium bisulfate (NaHSO. 4). Calcareous soils cannot be preserved using NaHSO. 4. because effervescence will promote the loss of analytes, and short holding times before
