prevent contamination. Sample vials/bottles should only be opened immediately before usage and capped immediately after. 4.2 Headspace in the sample vials/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.
Sampling Procedures: 1. Obtain the proper sample containers for the VOC or EPA 524, 624, or 8260 method. MTA uses three 40 ml voa vials preserved with HCl. 2. Tap each vial in the upright position to drain the preservative from the cap. DO NOT RINSE VIAL BEFORE COLLECTION. Do not open the vial until ready to collect the sample.

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
1.4 In order to accommodate analysis of a variety of sample matrices and VOCs, a matrix modifier (Sec. 7.7) is generally recommended to be used with this method. The matrix modifier is a water soluble salt solution that is added to each sample and standard vial prior to analysis.
6.1-4.1.3 Preparation of Containers for Volatile Organic Analytes Requires (2) 40-ml glass vials per water sample and 8-oz wide mouth glass jars with teflon liner for concentrated waste samples. 1. Wash vials, septa, teflon liners, and closures in hot tap water with laboratory grade non-phosphate detergent (e.g. Alconox). 2.
of volatile organic compounds (VOC) should be taken from areas of low turbulence to reduce the amount of entrapped air in the sample. •VOCs could be driven off to the atmosphere (as outgas) in turbulent sections of the flow stream •The “no head space” requirement for VOC sample containers, meaning no air space in the

Volatile Organic Chemicals. Samples collected for Volatile Organic Chemical (VOC) analysis need to be collected in pre-cleaned, pre-preserved 40 mL vials that are available at the laboratory. These vials contain hydrochloric acid (HCl) and therefore should be handled with caution. Take care not to touch or otherwise contaminate the inside of
Within a sample vial the unoccupied area above the sample is commonly referred to as the head space. Using static headspace, sealed vials containing sample are gently heated to drive VOC compounds out of the sample matrix into equilibrium with the gas phase.
