S2 PICOFOX is the worldwide first and only transportable TXRF-device with detection limits in the lower pg, ppb and ppm-regions.

The advantages of TXRF become especially effective in cases of very small sample amounts, liquid samples with high matrix content and frequently changing sample types. The method impresses particularly through its universal applicability.

Easy sample preparation

TXRF analysis is suitable for all types of samples, digestion is not always required. The sample, which must be placed on a sample carrier, can be prepared using different methods.

  • Liquids are pipetted directly onto the sample carrier and dried subsequently
  • Powder samples can be applied directly to the sample carrier or prepared as suspension
  • Single micro or nanoparticles can be prepared in a similar way.
