Boron is prepared by dry ashing of plant sample and analyzed using Inductively Coupled Plasma-Optical Emission Spectrometer. Samples and standards are nebulized and the resulting aerosol is transported by argon carrier gas to the plasma torch. Element-specific emission spectra are produced by radio frequency inductively coupled plasma. The spectra are dispersed by a grating spectrometer, and the intensities of the emission lines are monitored by photosensitive devices. Photo currents from the photosensitive device are processed and controlled by a computer system.
Note: To determine boron, the sample weight required is at least 4 g of plant sample.
