Boron determination in steels by inductively coupled plasma atomic emission spectrometry. Comparative study of spark ablation and pneumatic nebulization sampling systems

An experimental study for the determination of boron in steels by inductively coupled plasma atomic emission spectrometry is presented. A comparison is made of spark ablation and pneumatic nebulization (after microwave digestion) sampling systems. A one-step microwave digestion procedure for total b...
