“…The authors of [24][25] proposed an a priori approach to calculate RSC. However, variation of the matrix mass when analyzing other samples is expected to result in variation of main parameters of the plasma plume (for example, lifetime T 0 [26]) and relative yield of ions of different impurities from laser-produced plasma. Such a "matrix effect" was reported by several authors [27,28].…”

“…Experiments were made with a mass-spectrometer EMAL-2 [26] using a pulsed Nd: YAG laser with a repetition rate of 50Hz operated in the regime of min imal longtime instability of the output power [30][31]. The analytical part of the massspectrometer was calibrated according to recommendations of [32] to ensure proper accounting for the influence of the instrumental factor on the mass discrimination of ions along the flight path in the mass-spectrometer.…”

“…This problem could be solved in two ways. In LIMS with Mattauch-Herzog mass analysers, 39 a high acceleration energy is used. At 20,000 eV average ion energy, a ± 2% energy window allows the transmission of ions with an 800 eV range of energy that is more than enough.…”

At the beginning of the age of laser-ionisation mass spectrometry (LIMS) increasing numbers of publications were observed. However, later the method began to run into obstacles associated with poor reproducibility of analysis and large variations in elemental sensitivities so that the wide interest of the scientific community in the method faded away. However, the results described here show that the current knowledge of laser plasma processes, together with modern technical solutions to ion separation and quantification with time-of-flight (ToF) mass spectrometry, allow one to overcome the above-mentioned obstacles in LIMS. Thus, the performance in direct-sampling solid analysis demonstrated by the LAMAS-10M instrument is similar to that typically obtained by laser ablation/inductively-coupled plasma mass spectrometry (LA-ICP-MS) and glow-discharge mass spectrometry (GD-MS) methods. At the same time, there are additional advantages, including compactness of the instrument, absence of the need for expensive consumables and freedom from mass line interferences. Direct-sampling elemental LIMS is discussed as a promising alternative to LA-ICP-MS and GD-MS. Existing and prospective approaches to designing direct-sampling laser-ionisation mass spectrometers are theoretically justified. Factors affecting the main performance criteria, such as reproducibility, correctness, variations of relative sensitivity factors, linear dynamic range and resolution are considered. The demonstrated reproducibility, resolution, low-ppb limit of detection and one order-of-magnitude variation in elemental sensitivity are not the limit for direct-sampling laser-ionisation mass spectrometry of solid samples. Ways of improving LI-ToF-MS instrumental performance are discussed and theoretically justified.
