Aluminum Alloys Plus all the others too
LIBS (Laser Induced Breakdown Spectroscopy) has been used for more than 30 years as a laboratory technique  for analyzing any element in the periodic table. It is a type of optical emission spectroscopy used to measure elemental concentrations in a material. SkyAps uses a patented stack-spectrometer design. Its unique design offers a wide wavelength range and yields the best resolution of any handheld LIBS. The key to good LIBS analysis is creating a good plasma. The best plasma’s come from the highest power densities on the sample. The Z’s PULSAR laser technology fires laser pulses in the 5-6 mJ/pulse range, at up to 50 Hz frequencies, with 1 ns wide pulses. It is well established that mJoule, rather than micro-joule laser pulses yield superior analytical results.

LIBS Handheld Spectroscopy

The Z-200 has a standard range of 190 nm – 615 nm. The Z-200 can measure the emission of every element from hydrogen (H) to uranium (U) with the exception of: H, F, Br, Cl, N, O, S, Rb, Ce and K*. *K: For potassium, the best line is > 615 nm. K can be measured with the Z-200 but only for cases where the concentration is greater than 1-2% and there is very little iron interference. The Z-200 is the most portable, high performance LIBS analyzer ever created. It’s advanced technology includes on-board argon purge to deliver quantitative results; laser burst surface cleaning to eliminate grinding or surface prep; laser rastering for improved precision.

The Z-300 accomplishes what no other portable analyzer has done. It’s a handheld analyzer that measures every element in the Periodic Table.

The Z-300 is revolutionary. It’s the most portable, high performance LIBS analyzer ever created. Its advanced technology includes a stacked, high resolution spectrometer that spans from 190 nm – 950 nm, thus covering the emission lines for every element from H to U. The spectrometer can be operated in either gated or ungated mode. It uniquely features an on-board argon purge to deliver higher-precision, quantitative results; laser burst surface cleaning and rastering to eliminate grinding or surface prep and improved accuracy. The Z’s Android-based operating system is as friendly and intuitive as a Smartphone, and it supports numerous analytical Apps for a variety of sample types.

Additional range compared to Z-200 model provides additional elements
H, N, O, F, Cl, Br, Rb, Cs, K, S.

Z-50 is a basic alloy sorter. Like the other air-burn LIBS units, the Z-50 will sort common alloys, but with the benefit that it won’t require grinding every sample. It’s the least expensive handheld LIBS available, it does NOT use argon (air burn only), and is ideal for basic alloy grade sorting. It features the same powerful laser, rangy spectrometer, camera, Wifi as the Z-200.


Unique to the industry: Want to start simple, and add argon later? If you buy the Z-50 you can always upgrade to the Z-200, and get at least 90% of what you paid credited towards the new model.

Four reasons to consider a handheld LIBS gun versus X-ray:

Reason 1 - You simply don’t want to deal with radiation regulations, badges, and inspections, then get the Z. Both the Z-200 and Z-50 will sort all your alloys. The Z-200 will sort more alloys, more precisely, because the argon purge provides 10x better precision than air-burn.

Reason 2 - A priority is to sort aluminum alloys as precisely and as fast as possible, especially when dealing with grades that differ only by fine chemistry differences. For example, alloys that differ by small amounts of Mg, which is hard to measure with X-ray. For example sorting 3003, 3004 and 3005 quickly, or 356 and 357. These are a few of many examples.

Reason 3 - You must measure the elements Li, Be, B, C, Na, and low concentrations (< 0.2%) of Mg, Al and Si in various alloys. Handheld X-ray cannot measure Li, Be, B, C, or Na (sodium) at all.

Reason 4 - You’ve broken detectors or tubes and you just don’t want to use X-ray anymore, even though SciAps offers the lowest X-ray service costs of any brand. Good news! The Z has no detectors or tubes to break. Poke away at the aperture, you can’t damage the Quartz blast shield. In fact, except for the laser diode array, the most expensive components to repair on the Z range from $100-$500. The diode array costs $1,200 but they’re virtually impossible to break.
