“…Each aerosol droplet undergoes a sequence of processes during the~1 to 3 ms it travels through the ICP, including droplet desolvation, vaporization of the remaining particle (nanoparticle and any other dissolved solids in the sample), atomization, ionization, and diffusion of ions in the plasma prior to being sampled by the mass spectrometer [66], as shown in Fig. 2.…”

From its early beginnings in characterizing aerosol particles to its recent applications for investigating natural waters and waste streams, single particle inductively coupled plasma-mass spectrometry (spICP-MS) has proven to be a powerful technique for the detection and characterization of aqueous dispersions of metal-containing nanomaterials. Combining the high-throughput of an ensemble technique with the specificity of a single particle counting technique and the elemental specificity of ICP-MS, spICP-MS is capable of rapidly providing researchers with information pertaining to size, size distribution, particle number concentration, and major elemental composition with minimal sample perturbation. Recently, advances in data acquisition, signal processing, and the implementation of alternative mass analyzers (e.g., time-of-flight) has resulted in a wider breadth of particle analyses and made significant progress toward overcoming many of the challenges in the quantitative analysis of nanoparticles. This review provides an overview of spICP-MS development from a niche technique to application for routine analysis, a discussion of the key issues for quantitative analysis, and examples of its further advancement for analysis of increasingly complex environmental and biological samples.

“…[19][20][21][22][23] Time-resolved measurement is not a new technique for ICP optical emission spectrometry (ICP-OES) and ICP-MS, but it has been mainly applied to the elemental analysis of airborne particle matter [31][32][33][34] and observation studies of particle decomposition inside the plasma. [35][36][37] In the past decade or so, time-resolved ICP-MS has attracted much attention for highly sensitive elemental and multiparametric analyses of single biological cells.…”

“…Zhaozhu et al have shown that the K + /Na + peak area ratio observed in droplets created with identical NaCl and KCl mole fractions increased as the relative humidity increased, indicating that the surface properties of the aerosol particles could be quite different from the composition of the droplet's core (Zhaozhu et al, 1998a,b). The effect of the Na + /K + signal intensity is but one aspect of the problem of matrix effects in quantitative analysis, and thus is proving a tremendous challenge in single particle analysis (Bate, Leake, Matthews, & Wallach, 1993;Cooks & Busch, 1983;Gross, Galli, Silva, & Prather, 2000;Kane & Johnston, 2000;Olesik, 1997;Schoolcraft, Constable, Zhigilei, & Garrison, 2000;Woods, Smith, Dessiaterik, Baer, & Miller, 2001;Xu, Balik, & Agnes, 2001;Zhaozhu et al, 1998aZhaozhu et al, ,b, 1996. The capability to obtain multiple samplings from a single particle may allow a profile of a particle's morphology, and possibly a better understanding of the matrix effects.…”
