The key point of this paper is to explore the limits of very high resolution spatial analysis of samples. This is achieved using 100fs pulses and a very small focal spot. Craters of 450nm where achieved while still detecting Na and K in a Mica sample. Detection limits as low as 220 10^-18g (6 10^6 atoms) for Na and 4.2 10^-15 g (3.2 10^7 atoms) for K were achieved.
Element Detection Limit (ppm) Wavelength (nm) Other Wavelengths (nm) Calibration Method Calibration Range (ppm) Notes
Na 2700.0000 (Calibration Curve Slope) 588.9900 589.59 Univariate -10.0000--10.0000 This detection limit corresponds to 102 10^-18g of sample due to the very small (1um) laser spot size
