Ambient ionization is achieved by spraying from a carbon nanotube (CNT)‐impregnated paper surface under the influence of small voltages (≥3 V). Organic molecules give simple high‐quality mass spectra without fragmentation in the positive or negative ion modes. Conventional field ionization is ruled out, and it appears that field emission of microdroplets occurs. Microscopic examination of the CNT...
Ein Stück Papier, das mit Kohlenstoffnanoröhren imprägniert ist, kann verwendet werden, um Ionen aus verschiedenen Analyten bei Spannungen bis hinab zu 3 V zu erzeugen. T. Pradeep et al. halten diese miniaturisierte Ionenquelle in ihrer Zuschrift auf S. 6046 ff. vor den Einlass eines Massenspektrometers, um das Massenspektrum aufzunehmen. Pestizide aus Orangenschalen, Inhaltsstoffe von Tabletten und...
