AttoMap™ - µXRF analytical microscope

from SIGRAY

The AttoMap™ x-ray analytical microscope offers the highest resolution and the highest sensitivity one can find in a laboratory based microXRF system. The AttoMap™ system can be used for transmission-based x-ray structural analysis as well as for fluorescence chemical mapping. The system has a chemical sensitivity of <1-10 ppm for trace element analysis and the measuring time is within 1 second.

Further information

The key advantages of the AttoMap™ system compared to standard µXRF systems are three major innovations developed by Sigray.

The patented FAAST™ x-ray source with 50X higher brightness than microfocus sources used in standard microXRFs
Proprietary, high efficiency x-ray mirror lens that provides a combination of small achromatic focus and large working distance for superior detection sensitivity and accuracy
Unique detector geometry enabled by the design of the x-ray mirror lens that collects 10X more fluorescence x-rays than conventional designs.

These innovations provide the AttoMap™ with the ultimate laboratory microXRF performance:

Substantially higher resolution at single digit microns-scale (e.g. 3-5 µm MTF) resolution versus conventional microXRF
- Detectability of nanoparticles down to 50-100 nm
Dramatically faster analytical speed of a single minute - rather than a half day - for equivalent measurements on an AttoMap™ versus a conventional microXRF with up to 500X higher throughput
Sub-ppm and sub-femtogram sensitivity in seconds
- >100X the sensitivity of standard microXRF
- Only microXRF that can map trace elements (conventional microXRF is capable of mapping only major constituents at reasonable throughputs, as it requires long spot acquisition times for trace elements)
Most accurate quantification capabilities and optional dual energy source for maximum flexibility
Ability to analyze buried microfeatures
