Headspace Gas Chromatography—for applications involving the solvent-free extraction of volatile compounds, it’s an unsurpassed technique, eliminating the time-consuming steps and risk of human error associated with other GC sample-preparation methods.
幸运8平台彩票Butylated hydroxytoluene (BHT) is a common food additive used to protect foods from spoilage. Concern exists that long-term human consumption of BHT may have potential health risks. Analysis of BHT is needed for both food quality and safety reasons.
Epichlorohydrin, a raw material found in resins, can occur in drinking water at concentration which are hazardous to human health. The use of ephichlorohydrin is increasingly regulated. This article presents an analytical technique to determine the concentration of epichlorohydrin in the drinking water, in response to the requirements of the European Normative 98/83/EC, which recommends limiting the concentration to a maximum of 0.1 ug/L.
This application note demonstrates the use of a new sample-introduction technology incorporated in TurboMatrix HS-110 Trap for U.S. EPA Method 8260B for analysis, identification and quantification of volatile organic compounds (VOCs) that have boiling points below 200 °C.
ASTM International publishes a number of different methods for the determination of volatile compounds in water-based coatings. Method D3960 is a gravimetric technique where a sample of known weight is baked under specific conditions; the % weight of volatile organic compounds (VOCs) is calculated from a series of measured masses. The method that was presented here will reliably analyze difficult compounds in a difficult matrix with great precision, linearity, and without carryover.
Consumables reference guide for the TurboMatrix Headspace. TurboMatrix Headspace and high-sensitivity Headspace Trap samplers provide unparalleled precision and ease of use for numerous GC or GC/MS volatile-analysis applications. The system can manage up to 12 samples simultaneously, ensuring that the next sample is ready for analysis upon completion of the previous run, achieving significant time savings.
Journal of Chromatographic Science - A new analytical method for the determination of halogenated and aromatic volatile organic compounds in groundwater, mineral water, and drinking water at concentrations ranging between 1–10000 ng/L is developed..
幸运8平台彩票The development of methodology to measure VOCs at low levels using GC-MS coupled with Headspace Trap sample introduction is described here. The methodology is based on U.S. EPA Method 8260B.
The Polymer Market consists of a huge diversity of manufacturers of industrial products running many different processes yet still facing similar challenges. There is more and more pressure to achieve high product quality and reduce costs in order to stay one step ahead of the competition.
This field application report describes the use of a TurboMatrix™ HS-110 Trap and Clarus® 500 GC/MS optimized for low-level determination of fuel oxygenates by U.S. Environmental Protection Agency Method 8260B using the new headspace-trap technology.
幸运8平台彩票2,4,6-trichloroanisole (TCA) is found in the cork used to seal glass wine bottles. The determination of TCA in wine is necessary due to the extremely low level of sensory perception for this compound. The literature reports taste thresholds to be between 4 and 10 parts per trillion (ppt) in white wines and between 10 and 30 ppt for the heavier red wines.1 Above these thresholds, wines have an undesirable flavor.
