Abstract

Systems and methods for analyzing ultra-low level concentration nanoparticles in semiconductor cleaning chemicals by single particle inductively coupled plasma mass spectrometry (spICP-MS) are described. In aspects, the methods described herein include determination factors that are specific to each of the chemical matrix and the type of analyte associated with the nanoparticles present in a fluid sample for both a particle baseline intensity value and a nanoparticle detection threshold.
