Analytical Applications

High Resolution LA-ICP-MS Systems

-Teledyne Cetac Technologies


Extreme short ATLEX laser pulses (< 4 ns) are used by various analytical tools e.g. excimer laser high-fluence ablation systems in connection to LA-ICP/ICPMS – spectroscopy. The Analyte.G2 includes the sub-4 ns pulse, 300 Hz excimer laser from ATL Lasertechnik.

The S155 sample cell is the premium large format-cell for LA-ICP-MS analysis. With a large stage movement of 155 x 105mm, the cell is spacious enough to accommodate up to twenty 25mm (1") rounds, or nine 25 x 50mm (1 x 2") thin sections. Various sample holders are available to fit a wide range of sample sizes and types.

APLI Systems

-Bruker Daltonics


APLI (Atmospheric Pressure Laser Ionization) is a breaking ionization method with unrivalled sensitivity and selectivity for demanding applications such as the determination of PAH at low concentrations, polymer research, etc..

The ionization is performed via a two-step absorption process which is more selective than the conventional one-step ionization process exhibited through APPI (Atmospheric Pressure Photo Ionizaition). A further benefit  is that APLI can be used for non-polar compounds whereas APPI and APCI (Atmospheric Pressure Chemical Ionization) are both restricted to the analysis of polar molecules. Using APLI for PAH determination, a S/N >100:1 can be achieved at a concentration of 1ppb.

Aerosol particle measurement

-AeroMegt GmbH


The LAAPTOF (Laser Ablation of Aerosol Particles Time Of Flight Mass Spectrometer) is a single particle aerosol mass spectrometer. The LAAPTOF records size and bipolar time of flight mass spectra for individual particles. The inlet system efficiently transmits particles of up to 2.5 µm, which are analyzed at a frequency of up to 300 Hz.

Applications of the LAAPTOF range from analytics of environmental and laboratory aerosols over industrial operation to fundamental research. Unlike instruments which analyze several particles at once, the LAAPTOF provides detailed information on chemistry and size of individual particles. It is therefore able to distinguish between internal and external mixtures of particles. This is vital to control processes to synthesize aerosol particles, which often need to produce chemically homogenous populations.
