Sampling Instructions for VOC Analysis

Sampling Instructions for VOC Analysis (Volatile Organic Chemical) How to Sample: 1.) The sample must be taken after any treatments and before entry into the distribution system. 2.) Remove any attachments from the tap, such as hoses, filters or aerators. 3.) Flush the water for a couple of minutes or until the water reaches a constant

METHOD 5021A VOLATILE ORGANIC COMPOUNDS IN VARIOUS SAMPLE

1.1 This method describes equilibrium-based static headspace preparation of volatile organic compounds (VOCs) in soil/sediment, solid waste, aqueous and water-miscible liquid samples for determination by gas chromatography (GC) or gas chromatography/mass spectrometry (GC/MS). This method is applicable to a wide range of organic compounds that

Taking a VOC (Volatile Organic Chemical) Sample Properly

Taking a VOC (Volatile Organic Chemical) Sample Properly Make sure you keep all the vials together the whole time you are taking your The samples must be sent to the lab immediately. The sample will NOT be usable if there is an air bubble in the sample. You will have to resample. Step One Get a Sample Kit From Your Lab – One vial will be
