Optimization of conditions for spectral determination of chlorine content in cement-based materials

Abstract: A combination laser/electrospark method is used for fast determination of chlorine in cement-based materials. Excitation of the spectra is carried out both directly in an ablation plume and when a pulsed electric discharge is applied to it. In both cases, we obtain calibration curves that are linear for the major concentration range of practical importance for the analyte element, up to 1.5%. The chlorine detection limit for the combination discharge approach is 0.05%. We consider the basic steps and character… Show more

“…The secondary excitation coupled to LIBS has a long history and has been shown as an effective means to boost sensitivity of the analysis. Examples include microwave, [32][33][34] glow discharge, 35,36 radiofrequency torch, 37 spark [38][39][40][41][42][43][44] and arc 45 as the sources of the secondary excitation. Relative to the singlepulse ablation, a longer sustained plasma at lower temperature ought to be productive in the enhanced formation of molecules in their excited emitting states.…”
