A Guide to the Novel Shimadzu GC-MS BFB Tuning for the Analysis of Volatile Organic Compounds in Environmental Samples The Environmental Protection Agency (EPA) establishes strict BFB tuning criteria to ensure the quality of the results when analyzing volatile compounds.
As stated previously the most common technique used to detect, identify and quantitate VOC is gas chromatography with flame ionization (FID), electron capture (ECD) or mass spectrometry (GC-MS) detection. Selection of a detection method requires consideration of various analytical parameters and regulatory requirements.

Oct 14, 2010 · The most popular current testing method for COD involves using sealed and heated (i.e., closed reflux) low-range (3-150 ppm) or high-range (20-1500 ppm) pre-prepared vials that change color from orange to green based on the amount of oxidation and that are read using a laboratory colorimeter COD Test Procedures
A total organic carbon (TOC) analyzer is an analytical instrument that measures the total amount of organic carbon contained in water. It is used for quality control of public drinking water, control and evaluation of pharmaceutical manufacturing processes , and a wide variety of other applications.

The instrumentation for DOC/TOC analysis consists of two interconnected modules: the Shimadzu TOC-V CSH Analyzer, and the Shimadzu ASI-V Autosampler. The Autosampler is designed to operate on samples or standards prepared in septa sealed 40 ml glass vials. The Autosampler holds a removable 68-vial rotating sample rack.
Consisting of PC-controlled and stand-alone models, the Shimadzu TOC-L Series of laboratory total organic carbon analyzers offers the optimum selection of performance features and options to meet the specific requirements of total organic carbon testing in a wide range of aqueous samples.
To follow US EPA guidelines for analyzing volatile organic compounds (VOCs) in water and other environmental samples, the use of a purge and trap is required for extracting and introducing the sample into a GCMS. Laboratories performing EPA methods EPA 524.2, EPA 524.3, or EPA 524.4 in support for complying with the Safe Drinking Water Act
Shimadzu Total Organic Carbon Analyzers (TOC) Total organic carbon analyzers measure the amount of organic, inorganic, or total carbon in water or soil samples. TOC is an important indicator of disinfection byproducts and the byproduct rule requires drinking water facilities to measure TOC removal. TOC also correlates with BOD or COD in many
