Thermo Scientific Niton Apollo LIBS Analyzer Repair

The Niton Apollo is the LIBS instrument in the Niton range, and that distinction decides how it is repaired. It focuses a laser onto the sample to form a plasma, carries that light through fiber optics to a spectrometer under high-purity argon purge, and returns carbon in low alloy and carbon steels along with carbon equivalency and thirteen further elements in about ten seconds — from a 6.4 lb handheld running on Milwaukee M18 battery packs. Nothing in that chain is X-ray hardware, so an Apollo diagnosed like an XRF analyzer gets diagnosed wrong.

June Company’s certified technicians repair the Niton Apollo for PMI inspectors, weld shops, pipeline and pressure-vessel teams, and steel fabricators. We diagnose and repair at the board and component level, and every instrument is functionally tested against a known reference sample before it ships back.

Common Niton Apollo problems we fix

• Laser output degradation — weak or inconsistent ablation, showing up as unstable results before it shows up as no result at all.
• Argon purge faults — leaks, regulator failures or restricted flow — carbon results depend entirely on the purge being right.
• Optical path and fiber contamination — plasma light not reaching the spectrometer cleanly.
• Spectrometer faults — peak positions shifting and element identification becoming unreliable.
• Ablation window and spark-position faults — the laser no longer focusing at the correct standoff.
• Carbon equivalency drift — CE values moving while the other thirteen elements continue to read normally.
• Milwaukee M18 battery interface faults — the hot-swap system not carrying between packs.
• Laser safety interlock and sample sensor faults — the analyzer refusing to fire — working as designed, and repairable.
• Display and control faults — the interface or trigger failing mid-shift.

FAQs

My carbon numbers are unstable but the other elements look fine. What is that? That pattern usually points at the argon purge or the laser rather than the spectrometer. Carbon is the element most sensitive to purge quality, which makes it the first symptom.

Do you actually service LIBS instruments, or only XRF? LIBS specifically. The Apollo is a laser and gas-path instrument, and we diagnose it as one rather than treating it like an XRF analyzer.
