“…These solvents were selected to represent a variety of compound classes, that is alcohols, aliphatic and aromatic hydrocarbons as well as real petrochemical samples. In ICP spectrometry with conventional nebuliser spray chamber systems, volatile solvents normally cause more optimisation problems than less volatile solvents due to an increased solvent vapour load of the plasma [1,2,3,4,5,6,7,8,12]. Therefore, to test the DIHEN in the presence of more difficult solvents ethanol and hexane were included.…”

“…evaporation rate). These differences can give rise to species-specific sensitivity, for example if the transport efficiency of analytes to the plasma changes with species volatility [6,7,8]. This will introduce systematic errors on total determinations unless each species' response factor and the species composition of the sample are known.…”

A preliminary investigation on the introduction of high carbon content solvents into inductively coupled plasma mass spectrometry (ICP-MS) by a direct injection high efficiency nebuliser (DIHEN) is presented. Ethanol, hexane, toluene and a natural gas condensate were introduced using a flow injection system. The performance for determinations of total concentrations of mercury present in organic solvents as different species was evaluated. The most critical operating parameters were the nebuliser gas flow rate and amount of oxygen added to the plasma. For the DIHEN a nebuliser gas flow rate of 0.3 L min(-1) and 50 mL min(-1) of oxygen added to the plasma auxiliary gas flow gave stable conditions and high analyte sensitivity. Species recoveries for HgCl(2), CH(3)HgCl, (CH(3))(2)Hg and Hg(0) in hexane were 99+/-4, 101+/-4, 95+/-4 and 104+/-7%, respectively. Detection limit for mercury in hexane was 85 pg mL(-1) based on 3 sigma of a (201)Hg-spiked blank. A gradual deposition was observed at the nebuliser tip, partly blocking the gas annulus. The rate of deposition seemed to be related to the amount of carbon introduced through the nebuliser. With the optimised conditions used in this work, the nebuliser could be used for approximately 50 hexane samples before cleaning was necessary.

This review covers the literature reported from January 1, 1977, to December 31, 1978, and includes procedures recorded in readily available journals, in Chemical Abstracts, and in Fertilizer Abstracts (62). Some selectivity has been exercised to include only those procedures especially pertinent for direct application to fertilizers, easily adapted to fertilizers, or containing information related to research in fertilizer methodology. In the Literature Cited section of this review, Fertilizer Abstracts (62) are abbreviated as Fert. A.
