Spectroscopic investigation of atomic and molecular species formed in a laser microprobe plasma using a wavelenth calibrated tunable dye laser

Creator:

Beenen, Gerhard Joseph

Abstract:

The temporal and spatial characteristics of a laser microprobe plume were investigated using the spectroscopic methods of emission, absorption and fluorescence. The plume was produced by rapid vaporization of a small quantity (1 μg) of a solid sample using a focussed pulsed dye laser (110 MW/cm²). For absorption and fluorescence...

A new general method for the optimization of HPLC ternary of pseudo-quaternary mobile phases and the separation of two new metabolites of nefopam from greyhound urine

Creator:

Chen, Hsiao and Chen, Xiao

Abstract:

A new general method is developed for the optimization of HPLC ternary or pseudo-quaternary mobile phases which are represented by the trilinear coordinate system. This method can predict the global optimum of the mobile phase composition. The global optimum composition along each edge of the triangle and the corresponding selectivity...
