Z-50 LIBS Analyzer


The alternative to the TSI ChemLite and ChemLite Plus LIBS units

The SciAps Z-50 is the handheld LIBS that offers fast, quantitative testing results without argon purge. With its expanded spectral range (190 nm – 625 nm), the Z-50 also provides lithium and sodium analysis, making it the perfect alternative to the former TSI ChemLite and ChemLite Plus LIBS units. We’ve worked closely with TSI users and performed extensive side-by-side testing to provide the performance and operation TSI customers have come to expect.

  • Handheld LIBS, weighing about 4.4 lbs.
  • Analyzes Li down to few ppm
  • Air-burn operation for six alloy bases: Al, Ti, stainless, Fe, Ni and Cu
  • May be operated under Class 1 conditions, provided sample sensor is engaged (engaged by default, password protected)
  • Internal camera and flatter nose-plate for easier testing on curved or irregular circles
  • 1-second tests like ChemLite and ChemLite Plus
  • Expanded Ti and Al libraries compatible with ChemLite user expectations
  • Detect down to 10 ppm Be contamination in aluminum and copper alloys

For the metals industry, the Z-50 is an inexpensive but reliable alloy sorting device, mostly for aluminum, titanium alloys, and stainless. It will reliably ID high-temp alloys, but we do not recommend use for precise analysis of high temp alloys like nickel, cobalt, refractory alloys and super-alloys. For precise analysis of nickel alloys and other high temps, use SciAps XRF analyzers.

Quick Product Comparison

Model Measure Li? Air-burn or Argon Purge? Spectral Range (nm)

8.25″ x 11.5″ x 4.5″


5″ color touchscreen, smartphone-type display – PowerVR SGX540 3D graphic

Sample viewing

On-board camera/video for viewing sample before and during analysis, laser spot finder to show where laser strikes sample.


Z-direction stage, computer controlled for manually or automatically adjusting laser focus location on sample —essential for liquids analysis.

Comms/Data Transfer

Wifi, Bluetooth, USB. Connectivity to most devices, including SciAps ProfileBuilder PC software.

Excitation Source

5-6 mJ/pulse, 50 Hz repetition rate, 1064 nm laser source

Processing Electronics

ARM Cortex -A9 dual-core / 1.2 GHz Memory: 1 GB DDR2 RAM, 1 GB NAND

Operation Air Burn

The Z-50 operates in ambient environment, not argon purge. Users may update the Z-50 to a Z-200 or any other model for the difference in price.

Laser Raster

On-board XY stage for rastering laser to discrete locations for targeted analysis or averaging. Typically raster in 3 locations.

Calibration Check

Internal shutter is also 316 stainless for totally automated calibration and wavelength scale validation.


On-board rechargeable Li-ion battery, rechargeable inside device or with external charger, AC power.

Drift Correction

Automated drift correction using factory provided or user provided reference materials.

Grade library (alloy)

500+ grades, multiple libraries supported, grades may be added on analyzer or via PC software package (ProfileBuilder).

Data Storage

Results Storage: 8 GB SD


Password protected usage (user level) and internal settings (admin)
