Mass spec à la laser· The Leybold-Heraeus microprobe solid state mass s p e c t r o m e t e r significantly advances your analytical and research technology. Your microprobe analysis detection limits have now been realistically extended far beyond your imagination. The Leybold-Heraeus LAMMA 500 is why. Its laser microprobe, coupled to a time-of-flight mass spectrometer gives you mass spectra of unheard of sensitivity and lateral resolution—for virtually any type of solid sample. Now, you can apply all the versatility of mass spectrometry to both organic and inorganic samples—or mixes—with microprobe selectivity. The LAMMA 500 lets you analyze so much more—or so much less— simply and reliably.
R e m a r k a b l e simplicity. Our Laser Microprobe Mass Analyzer views your sample with a high resolution optical microscope. A small spotting laser lets you select the precise point for analysis—even less than 1 micron in diameter. The high power pulse laser strikes exactly the same area, evaporates and ionizes it. The TOF mass spec-
trometer produces the complete mass spectrum for each laser shot in either positive or negative ions. In less than one second, and you can change samples in less than three minutes. • Lateral resolution • D e p t h of analysis • Detection limit • Detectable concentration • Mass resolution (lead isotopes) • Speed of analysis • Sample c h a n g i n g time

analyzing single atmospheric dust particles both from the environment, and absorbed in tissue. LAMMA 500 makes investigating inclusions in polymers and other small defects in any type of material a routine operation, regardless of "whether the substrate and defect are organic, inorganic, or both.

L A M M A 500 performance characteristics are uncharacteristic.
Although these operating principles are simplified, and understated, it's obvious LAMMA 500 has created a new dimension in analyses capabilities. Analyses results confirm that fact.
A v e r s a t i l e LAMMA 5 0 0 for you? LAMMA 500 is designed for analytical and research applications in organic and inorganic chemistry, materials analysis, polymer chemistry, coatings research, metallurgy, mineralogy, corrosion studies, environmental studies (especially particulates and fibers), biological and medical studies of tissue, and forensic science.
