Latest App Notes & Case Studies

The recent Deepwater Horizon oil spill in the Gulf of Mexico created concerns over the safety of seafood that can get potentially contaminated with Polycyclic Aromatic Hydrocarbons (PAHs) from crude oil. The US Environmental Protection Agency identifies PAHs as critical pollutants harmful to human health. Some of these compounds are known carcinogens.

Cyanide is a well known acute toxin that prevents cellular respiration by irreversibly binding with the iron in cytochrome C oxidase. In addition, thiocyanate, which is metabolized from cyanide, interferes with iodine uptake by the thyroid gland, causing goiters and other long-term iodine deficiency diseases.

EPA Method 524.2, “Measurement of Purgeable Organic Compounds in Water by Capillary Column Gas Chromatography/Mass Spectrometry”, is a general-purpose method for the identification and simultaneous measurement of purgeable volatile organic compounds in surface water, groundwater, and drinking water.

Proton Transfer Reaction-Mass Spectometry (PTR-MS) with its online measurement capabilities enables researchers to quantify compounds in the nose space air of test persons.

Airborne molecular contamination (AMC) is a concern for any high technology manufacturing process, especially in the microelectronics industry. Organic contamination may cause adverse effects on production tools and consequently increase costs for high-tech companies.

Common methods of analyzing compounds released when leaves are wounded do not have the capability to monitor reactions of the plants in a time resolution high enough to reveal underlying reaction sequences.

VOCs are chemicals that evaporate easily at room temperature. Organic refers to carbon-based molecules. Many of which are known to be harmful to human health. Chemical contamination of indoor air is a contributing factor to the so called "Sick Building Syndrome".
