Z-903 LIBS Analyzer

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.

Z-903 for geochem & soils

SciAps Z-903 handheld LIBS offers two distinct features not available with handheld X-ray analyzers. First, the Z analyzes elements that X-ray cannot, including lithium, beryllium, boron, carbon, fluorine, and sodium. Second, the Z performs micro-analysis in the field, something not available with any other analyzer. The laser beam is 100 um, and the Z can raster the laser in discrete increments in two dimensions. This allows for heat mapping of regions on rocks. And, the Z is generally better on low concentrations of major elements or metals including magnesium and aluminum compared to handheld XRF.

Bulk samples
and micro-analysis

The Z is the world’s only handheld offering elemental micro-analysis in the field. Users may set up the raster to a grid pattern, using the 100 um laser spot size for elemental heat mapping point-by-point. For bulk samples, the Z can be set to average results from every raster location for a bulk sample result, just like handheld XRF analysis.

Some of many Z-903 applications

In-field Lithium

Trace level lithium analysis is best done using the strong 675 nm Li line. Often users also want to measure sulfur (in the 930 nm) and light metals or transition elements (typically B, Mg, Ca, K) in the 200 – 400 nm range.  The Z-903 is perfect because it covers the full range.

Fluorine (PFAS) in Food Packaging Materials

Fluorine is the market for PFAS (Per- and polyfluoroalkyl substances).  F is measured in the 720 nm spectral region.  Many users also want to measure heavy metals as well in the 200 – 350 nm range.

Supply Chain Requirements

Need to keep conflict minerals out of your supply chain? Dr. Richard Hark of Yale University uses geochemical mapping with a full spectrum LIBS to identify conflict minerals.

Glass Chemistry

This application requires analysis of both boron (B) and sodium (Na), which reside at very different wavelengths 210 nm and 585 nm, respectively.  The Z-903 is the LIBS of choice because it covers this wide range.

Trans-uranic Analysis

Los Alamos personnel need a method to perform rapid chemical analysis in a nuclear facility. Ben Manard and his colleagues use the SciAps Z-300 handheld LIBS to quantify levels of rare earth elements in a uranium oxide matrix.

Z-900 Series LIBS Analyzers

ModelRangeBest Application
Z-901200 – 420 nmGeneral alloy testing for scrap sorting, PMI/NDT or quality assurance. Does not measure carbon.
Z-902210 – 625 nmSame as 901 except spectral range extended to include lithium for users that must measure Li in aluminum or other alloys.
Z-902 Carbon190 – 440 nmIdeal for carbon analysis in steel and L, H-grade stainless and nickel alloys. Also measures general alloy elements and carbon equivalents, residuals. Does NOT measure Li.
Z-901 CSi190 – 260 nmAnalyzes carbon and silicon only. The perfect complement to your XRF.
Z-903190 – 950 nmMeasures every element in the periodic table. Measures carbon in geochemical samples and total organic carbon (TOC). Not for carbon in steel or stainless alloys.
Z-903 Carbon190 – 625 nmSame as 902 Carbon, except spectral range is extended to measure Li in alloys.
Z-901 Beryllium210 – 440 nmPurpose built for beryllium measurements, generally paired with XRF to cover all 13 EPA Priority Pollutant elements. Handheld XRF cannot measure Be.
Z-901 Lithium480 – 690 nmPurpose built for lithium in soils, rocks and brines.
Z-901 Fluorine600 – 720 nmPurpose built for fluorine analysis for PFAS in various materials. Note: uses helium purge rather than argon purge.
Factory calibrations do not include every element, but are provided for a set 15-20 elements depending on the application. Elements exclude unstable and radioactive elements. Detection limits vary greatly by element and sample type.
