Headspace Trap, Alternative solution to Purge and Trap
U.S. EPA method 8260 is a widely used GC/MS environmental method, for the analysis of volatile organic compounds in a variety of sample matrices. The most common sample introduction technique for this analysis is currently purge and trap; this webinar will highlight an alternate technique to introduce VOC’s into a GCMS system, utilizing headspace with trap technology.
Headspace trap technology provides laboratories the benefits of static headspace sampling, (no carry-over, no cross-contamination, no foaming, and ease of sample preparation) along with the detection limit improvement of a trap allowing a 80x to 100x more sensitivity vs. static headspace. This technology is capable of sampling the entire headspace to meet low level 8260 requirements, without introducing matrix interferences into you chromatographic system. |

An Overview of Speciated Inorganic Analysis in Water
The measurement of metals in environmental, clinical, and industrial matrices is well established and can provide information on quality, nutrition and other important parameters. But does the total metal content of each element give us enough information to make decisions on metabolism, bioavailability, and mobility in the environment or human body? Speciated analysis, describing the metal content in terms of valence state or organic compound, can provide additional information that can be used to more completely understand the action of metals in our world.
This webinar will summarize the status of speciation analysis today. Method development for several elemental species will be described and routine application outlined. |

Overview of WEEE/RoHS Requirements
Polybrominated Diphenyl Ethers (PBDEs) and several metals are under scrutiny as result of their global presence and rapid bioaccumulation. Recently, legislation in the European Union (EU) requires reduction in these hazardous materials in electronic components sold in the EU, to reduce environmental impact during disposal. The Reduction in Hazardous Substances (RoHS) legislation has global impact for manufacturing firms and environmental laboratories.
This webinar will discuss regulatory and analytical requirements for organic and inorganic analyses. |
