Z-903 : GeoChem & Soils analyzer

One analyzer, every element

Every element in the periodic table, in seconds, in a handheld

One analyzer, every element

The Z-903 accomplishes what no other portable analyzer has done. It’s a handheld analyzer that measures every element in the periodic table of the elements – from H to U.

It uses the same powerful laser as SciAps other Z-900 models, but with an extended spectrometer range from 190 nm out to 950 nm.

  • The extended range allows emission lines from elements H, F, N, O, Br, Cl, Rb, Cs and S to be measured. These lines cannot be measured with the other Z-900 series analyzers.
  • There are other benefits to the extended range. For example, it measures a more sensitive line for lithium near 675 nm to achieve limits of detection in the 2-5 ppm range.
  • It also measures a more sensitive, and interference-free line for potassium (K). The more traditional potassium lines have heavy iron interference, whereas the line used by the Z-903 is free of such interference.

In use globally

The Z-903 is most widely used for mineral exploration including lithium in both hard rock and brines. It is also used in forensics, authentication, archeology and oil/gas exploration due to the wide elemental range.

Complete user control

The laser strike pattern, cleaning shots, spectrometer settings are all under user control. The analyzer includes advanced software for modifying all settings, comparing spectral data, and for generating quantitative calibration curves. The Z-903 features the same Android OS and intuitive App-driven software as all other SciAps models.

GeoChem Pro Mode

This application, available as an option, allows the Z-903 portable LIBS analyzer to have the unique ability to perform basic elemental mapping in the field.

In the example below, the LIBS elemental distribution mapping for Iron shows an excellent correlation with the XFM data, the use of third party data processing software such as Reflex ioGAS allows rapid processing of the information on field.

Development of applications in the field of Geosciences:

LIBS is an innovative analysis technique that opens new doors and capabilities previously unknown. The development of complex applications in the geological, mining and environmental fields can nevertheless be a hindrance because they require internal resources and variable development time.

To address this issue Quantum-RX works in close collaboration with the company INGEN.


We are both customers and suppliers to each other and have extensive experience working together.

INGEN has already developed dozens of LIBS calibrations in the field of Geosciences to meet the needs of our joint customers, this application library is therefore already ready and available for fast, easy and transparent integration into our portable LIBS.

Entrust us with your analytical needs and your projects, Quantum-RX and INGEN will take care of the preliminary feasibility study, turnkey development, and implementation.
