Sample Handling Vials - .NET Framework

Vials and inserts are made of inert, high-purity, chemically-stable borosilicate glass to exacting specifications, individually heat-treated to burn off any impurities, then packaged in a cleanroom environment. Choose from crimp, snap, and screw types or mix and match vials and caps to your application. Most vials are

SAMPLING METHOD FOR VOLATILE ORGANIC COMPOUNDS (SMVOC)

SAMPLING METHOD FOR VOLATILE ORGANIC COMPOUNDS (SMVOC) 1.0 SCOPE AND APPLICATION 1.1 Method 0031 is used to determine volatile organic compounds in gaseous em issions from a wide variety of stationary sources including hazardous waste incinerators. The following compounds may be determined by this method: Compound Boiling Point ( EC) CAS No. a

Volatile Organic Compound (VOC's) Sample Collection

1. Collect all samples in duplicate using properly prepared 40 to 120 ml borosilicate glass containers with a teflon faced silicone septa. Vials should be treated as directed to be free of organic chemical contamination. 2. If samples contain residual chlorine and measurements of the concentrations of disinfection by-products (trihalomethanes

Method 625: Base/Neutrals and Acids

METHODS FOR ORGANIC CHEMICAL ANALYSIS OF MUNICIPAL AND INDUSTRIAL WASTEWATER. METHOD 625—BASE/NEUTRALS AND ACIDS. 1. Scope and Application . 1.1.

Volatile Organic Compound (VOC) Testing and Analysis

Volatile Organic Compound (VOC) Testing and Analysis. Volatile Organic Compound or VOC Testing and Analysis using techniques such as GC-MS. Volatile Organic Compounds (VOCs) are present in all natural and synthetic materials, and can exist not only as structurally-diverse liquids and solids but also as vapours, and are thus a significant airbourne consideration when biomonitoring human

Behavior and Determination of Volatile Organic Compounds in

They calculated relative volatile losses for 35 organic chemicals placed in a 30-cm-thick layer 100 cm below a soil surface. Two uniform soil conditions were simulated in soils of sandy or clayey texture and (1) with no water evaporation or (2) at a low, steady 0.1 cm/day water evaporation rate.

Passive air sampling for semi-volatile organic chemicals

A distinct set of PASs has been developed for semi-volatile organic chemicals (SVOCs). The term SVOCs comprises organic molecules that can occur to a significant extent in both the gas-phase and condensed phases, which corresponds to the vapour pressure range of approx. 10 −1 to 10 −6 Pa. The group of SVOCs comprises a large number of
