“…Exceptional attributes of ICP-TOF-MS, such as high speed of data acquisition, an ability to obtain a full elemental analysis in a time-frame suited to a transient inlet system and significantly better, as compared with widely used quadrupole ICP-MS, the precision of the measurements generate increasing interest in the technique. The ICP-TOF-MS has been successfully coupled to LA, [120][121][122][123][124][125][126] ETV, 127 GC, [128][129][130][131][132] liquid chromatography, 133,134 CE 135,136 and FIA.

“…ICPMS instruments with time-of-flight (TOF) analyzers were recently demonstrated with LA sampling. 54 The TOF approach allows the collection of several thousand complete mass spectra per second. Owing to the transient nature of LA, ICPMS with a TOF analyzer is potentially advantageous for multielemental determinations, although to date only limited research has been conducted.…”

Laser ablation (LA) is a unique technique to transform a solid sample into vapor‐phase constituents, which then can be chemically analyzed by atomic spectroscopy. Ablation brings many exciting capabilities to the field of chemical analysis, primarily because of the laser‐beam properties. The ability to analyze directly any solid samplewithout sample preparation and minimal sample‐quantity requirements are just some of the unique capabilities. This article discusses current issues related to using LA in atomic spectroscopy. A general introduction to LA sampling is presented along with a comparison with other solid sampling techniques. The critical issues for all analytical techniques are calibration, accuracy, and sensitivity. Techniques that have been demonstrated to address these analytical characteristics and define these parameters for LA are investigated in detail. Finally, many unique applications are described, ranging from dating geological materials to providing crime‐scene evidence. Most of these applications could not be performed without the use of a laser beam. The inductively coupled plasma (ICP) will be emphasized in this article because it is currently the most prevalent excitation and ionization source for chemical analysis using LA.

“…A minimum of 5 to 10 ms dwelltime is necessary for the determination of each mass. Vaporization of micro samples by an electrothermal or laser pulse and ionizations by an ICP generates transient signals with a width of a few hundreds of ms [4]. Since the typical timescale for scanning through the mass range from, e.g.…”

The aim of this extensive aerosol measurement campaign was to obtain a database for model-calculations of arctic aerosol, which play an important role in the global climate change. The ASTAR project was centered on two aircraft measurement campaigns, scheduled from 2004 to 2005, addressing both aerosol and cloud measurements, combined with ground-based and satellite observations. In the present paper one example for the analysis of ground-based aerosol particles is described. The sampling of aerosol particles was performed in a well-known manner by impaction of the particles on cleaned graphite targets. By means of a cascade impactor eight size classes between 0.35 and 16.6 Am aerodynamic diameters were separated. To analyze the metal content in the aerosol particles the targets were rapidly heated up to 2700 -C in an inductively heated vaporizer system (IHVS). An argon flow transports the vaporized sample material into the inductively coupled plasma (ICP) used as ionization source for the time of flight-mass spectrometer (TOF-MS). The simultaneous extraction of the ions from the plasma, as realized in the TOF instrument, allows to obtain the full mass spectrum of the sample during the vaporization pulse without any limitation in the number of elements detected. With optimized experimental parameters the element content in arctic aerosol particles was determined in a mass range between 7 Li and 209 Bi. Comparing the size distribution of the elemental content of the aerosol particles, two different meteorological situations were verified. For calibration acidified reference solutions were placed on the cleaned target inside the IHVS. The limits of detection (LOD) for the element mass on the target range between 2 and 200 pg for the elements studied, except Na, Mg, and Cr, which are influenced by high background. D
