ICP Sample Matrix Identification by Acoustic Signature
Abstract:A novel technique for rapidly determining properties of the sample matrix of nebulized samples in inductively coupled plasma spectrometry via acoustic signature is discussed. Properties such as surface tension and high dissolved salts can be determined by analyzing the acoustic signal produced by the sample nebulization process. With digital signal processing equipment, determination of the presence of organic matrices or high-salt matrices should be possible before the plasma or the nebulizer is adversely affected.
