Z-50 LIBS Analyzer

The alternative to the TSI ChemLite and ChemLite + LIBS units

The TSI ChemLite was a good handheld LIBS analyzer. We know because we’ve competed against it for years and we congratulate the LIBS team at TSI for developing and marketing such an impressive product.

Due to events out of their control, the TSI LIBS group has recently announced they’re exiting the handheld LIBS business. Over the past several days, we’ve worked closely with TSI users to modify the SciAps handheld LIBS to provide the performance and operation TSI customers have come to expect. After extensive side-by-side testing, we’re pleased to announce the Z-50, the SciAps handheld LIBS that offers fast, quantitative testing results WITHOUT argon purge.

  • Handheld LIBS, weighing about 4 lbs.
  • Air-burn operation for five alloy bases: Al, Ti, stainless, Fe and Ni
  • 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 +
  • Expanded Ti and Al libraries compatible with ChemLite user expectations
  • Detect down to 10 ppm Li and Be contamination in aluminum alloys

Great News: If you buy a Z-50 and need improved precision or carbon analysis, we offer attractive trade-ins to more advanced argon purge models. Even carbon. Defy Obsolescence!

For the metals industry, the Z-50 is an inexpensive but reliable alloy sorting device, mostly for aluminum, titanium alloys, and stainless. It will ID high-temp alloys, but should not be used for precise Ni analysis. For precise analysis of nickel alloys and other high temps, use the SciAps X handheld XRF analyzer.

Z-50 Analytical Range

Typically 15-20 elements calibrated, specific elements depending on alloy base.

Z-50 Spectrometer/Range

190 nm – 625 nm



4 lbs. with battery


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)


CE, RoHS, USFDA registered. Class 3b laser. Sample sensor on board, allows for operation under Class 1 conditions, subject to local LSO approval.
