  • Measuring Odors From Livestock Operations
    Chemist Dick Pfeiffer uses a gas chromatograph/mass spectrometer to analyze compounds in odors collected from a swine production facility. Complaints about nuisance livestock odor in rural areas have become a problem nationwide. Scientists for the U.S. Department of Agriculture's are working
  • Features and Applications of Newly-Developed GC-TOFMS
    A gas-chromatograph mass spectrometer (GC-MS) is a combined analyzer that has superior ability in analyzing organic compounds qualitatively and quantitatively. The first part, gas chromatograph, separates the compounds included in a sample (mixture), then the second part, mass spectrometer, obtains
  • Tracking an Attacker of Saltcedar
    leaves were collected for identification by a gas chromatograph-mass spectrometer. Compounds emitted by just one sex were considered likely to be pheromone components. Then, using a technique called "electroantennographic detection, " the researchers measured electrical stimulation triggered
