Laser Desorption Ionization of As 2 Ch 3 (Ch = S, Se, and Te) Chalcogenides Using Quadrupole Ion Trap Time-of-Flight Mass Spectrometry: A Comparative Study

摘要: Laser desorption ionization using time-of-flight mass spectrometer afforded with quadrupole ion trap was used to study As2Ch3 (Ch = S, Se, and Te) bulk chalcogenide materials. The main goal of the is identification species present in plasma originating from interaction laser pulses solid state material. generated clusters both positive negative mode are identified as 10 unary (S p +/– As m ) 34 binary (As S for As2S3 glass, 2 (Se q 26 Se As2Se3 7 (Te r 23 Te As2Te3 fragmentation materials diminished some polymers this way 45 new, higher have been detected. This novel approach opens a new possibility spectrometry analysis chalcogenides well other
