Distribution of Foliar-applied Boron Measured by Spark-source Mass Spectrometry and Laser-probe Mass Spectrography

Distribution of Foliar-applied Boron Measured by Spark-source Mass Spectrometry and Laser-probe Mass Spectrography.

The distribution of foliar-applied boron ([(10)B]boric acid) in radish (Raphanus sativus L.) was studied using for analysis of the stable isotopes a technique allowing a high sensitivity: spark-source mass spectrometry. Boron was recovered in the nontreated aerial parts and in the roots; however, the greatest fraction was in the treated leaf. It was possible with a laser-probe mass spectrograph...

Experimental Study of Photon-Phonon Interactions in an Explosive by Laser Probe Mass Spectrography

We have shown in a series of previous papers the part of the molecular electronic structure played in the decomposition process of an explosive submitted to a shock wave. This part is important especially as regards energy transfer properties. This work is intented to investigate the process of these transfers by the study of photon-phonon interactions in this type of material. The experimental...

Isomeric identification by laser control mass spectrometry.

The influence shaped femtosecond laser pulses have on molecular photofragmentation and ionization, coupled with the intrinsic sensitivity of mass spectrometry, results in a powerful tool for fast, accurate, reproducible and quantitative isomeric identification. Complex phase functions are introduced to enhance differences during the laser-molecule interactions, which depend on geometric structu...
