“…Dissolved analyte can be introduced into the ICP as monodisperse microdroplets (or dried microdroplet particles) in order to have better control of sample-introduction related phenomena and thus better control of matrix effects and optimization for best absolute sensitivities. 9,[22][23][24][25] Discrete samples, such as single nanoparticles [26][27][28][29] or cells [30][31][32] can also be introduced within microdroplets for a more controlled sample introduction strategy compared to conventional pneumatic nebulization. For both single-nanoparticle and single-cell ICP-MS measurements, introduction of a sample with monodisperse microdroplets presents an attractive approach for quantitative transfer of analyte particles/cells into the plasma with the possibility of direct counting experiments for number concentration determinations.…”

“…A valve-based droplet direct injection system was evaluated by Shigeta et al 24 In this system, the sample solution was directly injected as a single droplet or a series of droplets into the ICP. The droplet volume could be controlled across a range of droplet sizes and the system could be applied to the direct injection of cells contained in a droplet.…”

SUMMARY OF CONTENTS This review covers developments in 'Atomic Spectrometry'. It covers atomic emission, absorption, fluorescence and mass spectrometry, but excludes material on speciation and coupled techniques which is included in a separate review. It should be read in conjunctionwith the other related reviews in the series. [1][2][3][4][5][6] Sample introductionThis section covers developments in sample introduction for all instrumental methods. LiquidsLiquid sample introduction relates to methods wherein the sample is introduced into the instrument in the form of a liquid, such as through nebulization or into a thermal vaporizer; whereas in vapour generation the sample is initially in the form of a liquid but is converted to a vapour prior to introduction into the instrument. Sample pre-treatment.A general review of on-line preconcentration for ICP-MS has been published by Das et al. 7 , covering solid phase methods and including 63 references. Several reviews of sample pretreatment methods used for atomic spectrometry are worth noting because they focus on specific areas: Kocurova et al. 8and Jain and Verma 9 have reviewed advances in DLLME (53 references) and SDME (407 references) respectively; Zhao et al. the same authors studied the stability of the labelled complexes at different pH and temperature, and when subject to separation using LC. They reported a significant decrease in stability when LC separation was used, and some degradation at 37 °C compared to 2 °C.Li et al. An immunoassay-linked method using gold nano-particles has been developed by Jarujamrus et al. 33 . In this approach the monoclonal antibody-chloramphenicol was attached to a solid support. Antigen-chloramphenicol was labelled with gold nano-particles (10 nm) at pH 9.5, attached to a bovine serum albumin protein and mixed with unlabelled antigenchloramphenicol, which was then added to the antibody-chloramphenicol. for U and Th respectively in water samples.

Introducing analytic samples into plasma leads to the generation of light and ions. By detecting these ions and light, trace quantities of elements within the samples can be analyzed. The light and ions are generated not only by the high temperature of the plasma but also as a result of the complex atomic/molecular process within plasma. By understanding this process, the characteristics of plasma (e.g. the connection between operating conditions of the analysis equipment and the results of the analysis) and the effect to elements other than analytes, a clear understanding of phenomena such as the matrix effect can be acquired. This report focuses on the atomic and molecular processes that occur within an argon inductively coupled plasma (ICP) and explains the various characteristics of such plasma.
