Journal ArticleDOI
Review of the state-of-the-art of laser ablation inductively coupled plasma mass spectrometry.
Joachim Koch,Detlef Günther +1 more
TL;DR: The performance of femtosecond LA-based analyses as one of the most important advancements made over the past years is discussed and the benefits offered by fs-LA in comparison to LA using nanosecond laser sources are demonstrated.
Journal ArticleDOI
Particle size distributions and compositions of aerosols produced by near-IR femto- and nanosecond laser ablation of brass
TL;DR: Particle size distributions and compositions of primary aerosols produced by means of near-IR femtosecond laser ablation of brass in He or Ar at atmospheric pressure have been measured.
Journal ArticleDOI
Capabilities of inductively coupled plasma mass spectrometry for the detection of nanoparticles carried by monodisperse microdroplets
Sabrina Gschwind,Luca Flamigni,Joachim Koch,Olga Borovinskaya,Sebastian Groh,Kay Niemax,Detlef Günther +6 more
TL;DR: In this article, a commercial micro-droplet generator was used to generate 30-40 µm droplets with nearly 100% efficiency and high uniformity to the inductively coupled plasma optical emission spectrometer (ICP-OES).
Journal ArticleDOI
Performance characteristics of ultra-violet femtosecond laser ablation inductively coupled plasma mass spectrometry at ∼265 and ∼200 nm
TL;DR: In this article, the analytical figures of merit of ultra-violet femtosecond laser ablation inductively coupled plasma mass spectrometry (UV-fs-LA-ICP-MS) using the 3rd and 4th harmonics of Ti:Sapphire (∼265 and ∼200 nm, respectively) were explored.
Journal ArticleDOI
Femtosecond laser ablation inductively coupled plasma mass spectrometry: achievements and remaining problems
Joachim Koch,Detlef Günther +1 more
TL;DR: The prospects of fs-LA as a way to improve the quantification capabilities of LA-ICP-MS using non-matrix-matched calibration is reported on and some of the remaining problems related to ICPinduced elemental fractionation which affect the overall accuracy of analysis are addressed.
