Analytical Chemistry
Researchers at California Institute of Technology have published new data on analytical chemistry
June 26th, 2007
Researchers detail in "Compact ambient pressure pyroelectric ion source for mass spectrometry," new data in analytical chemistry. "We present the construction and implementation of a compact, low-power ambient pressure pyroelectric ionization source. The source comprises a z-cut lithium niobate or lithium tantalate crystal with an attached resistive heater mounted in front of the atmospheric pressure inlet of an ion trap mass spectrometer," scientists in the United States report. "Positive and negative ion formation alternately results from thermally cycling the crystal over a narrow temperature range. Ionization of 1,1,1,3,3,3-hexafluoro-2-propanol or benzoic acid...
