When you need fast, accurate elemental analysis on-site — without shipping samples to a lab — the Portable LIBS Spectrometer changes the game entirely. Strukturnaya Diagnostika Pvt. Ltd. proudly introduces the LIS-02, a next-generation laser-induced breakdown spectroscopy instrument built for industrial professionals who can't afford delays or guesswork.

Whether you're verifying carbon content in steel, screening alloys at intake, or conducting quality checks on a production line, the LIS-02 delivers laboratory-grade results where your work actually happens.

What Is a Portable LIBS Spectrometer?

LIBS stands for Laser-Induced Breakdown Spectroscopy — a technique where a pulsed laser beam is focused on a material's surface, creating a tiny plasma. That plasma emits light unique to the elements present. The spectrometer captures and analyzes that light in milliseconds, giving you a precise elemental composition without any sample preparation.

Unlike traditional wet chemistry or X-ray fluorescence (XRF) methods, LIBS can detect light elements — most critically, carbon — which XRF devices struggle with. That's a critical advantage in metallurgical and industrial settings.

Introducing the Portable LIBS Spectrometer LIS-02

The LIS-02 is Strukturnaya Diagnostika's answer to the growing need for fast, mobile, and reliable elemental analysis. Compact enough to carry to a job site yet powerful enough to rival fixed laboratory instruments, it was engineered with the real-world demands of quality engineers, metallurgists, and R&D teams in mind.

Why Carbon Detection Matters — And Why LIBS Does It Best

Carbon is arguably the most important element in steel and cast iron. Even a 0.1% variation in carbon content can dramatically alter hardness, weldability, and fracture resistance. Yet most handheld XRF spectrometers simply cannot detect carbon reliably — their X-ray methodology doesn't interact with light elements the way LIBS does.

The Portable LIBS Spectrometer LIS-02 directly measures the carbon spectral emission line at 247.8 nm, giving you quantitative carbon readings that are accurate and reproducible — right at the source material.

This makes it indispensable for:

• Scrap metal sorting — Separate carbon steel from low-alloy or stainless grades instantly
• Incoming material verification — Confirm that supplied steel meets specification before it enters your process
• Weld quality checks — Verify base metal and filler composition at the joint
• Heat treatment validation — Confirm carbon levels before and after case hardening or annealing
• PMI (Positive Material Identification) — Required in pressure vessels, pipelines, and safety-critical structures

Portable LIBS Spectrometer in Real Industrial Settings

One of the biggest friction points in quality control has always been the gap between the lab and the shop floor. Samples get mislabeled. Results take hours. Decisions get delayed.

The LIS-02 Portable LIBS Spectrometer eliminates that gap. Strukturnaya Diagnostika's field teams have deployed the LIS-02 in steelworks, fabrication shops, foundries, and inspection services — consistently reducing material verification time from hours to seconds.

In one application, a structural steel fabricator used the LIS-02 to screen 400 incoming billets in a single shift. Previously, that work required lab sampling and a 24-hour turnaround. The LIS-02 completed it before the delivery truck left the yard.

How the LIS-02 Stands Apart from Competing Instruments

vs. Handheld XRF

XRF is widely used, but it has a well-known blind spot: light elements. Carbon, Boron, Lithium, and Beryllium are effectively invisible to most handheld XRF units. LIBS has no such limitation.

vs. Optical Emission Spectrometry (OES)

Bench-top OES instruments offer high accuracy but require sample polishing, argon purging, and a fixed lab setup. The LIS-02 needs none of that. It's ready to fire on a raw surface in seconds.

vs. Other Portable LIBS Units

Many portable LIBS instruments sacrifice carbon calibration accuracy for size. The LIS-02 uses multi-matrix calibration curves and built-in standardization routines specifically optimized for carbon steels, cast irons, stainless grades, and aluminum alloys — not a generic one-size-fits-all approach.

For carbon detection specifically, there is no more practical or accurate handheld solution available today. Strukturnaya Diagnostika built the LIS-02 to meet that need — and it delivers.

If precise, fast, field-ready elemental analysis matters to your operation, the Portable LIBS Spectrometer LIS-02 belongs in your quality toolkit.

❓ FAQs — Portable LIBS Spectrometer LIS-02

Q1: Can the LIS-02 detect carbon in low-alloy steel? Yes. The LIS-02 is specifically calibrated to detect carbon across a wide range — from ultra-low carbon steels (below 0.05% C) to high-carbon grades and cast irons. This is one of its primary differentiators from handheld XRF instruments.

Q2: Does the LIS-02 require sample preparation before analysis? No. One of the major practical advantages of LIBS technology is that it requires minimal to no sample preparation. The instrument can analyze a clean, ground surface directly. For painted or heavily oxidized surfaces, a quick wire brush or grind wheel pass improves accuracy.

Q3: How many elements can the LIS-02 analyze simultaneously? The LIS-02 can simultaneously detect and quantify over 25 elements including C, Si, Mn, Cr, Ni, Mo, V, Cu, Al, Fe, and more — depending on the calibration library loaded.

Q4: Is the LIS-02 suitable for non-metallic materials? While the LIS-02 is optimized for metals and alloys, LIBS technology can also be applied to ceramics, minerals, and polymers. Contact Strukturnaya Diagnostika to discuss custom calibration options for non-standard matrices.

Q5: What kind of after-sales support does Strukturnaya Diagnostika provide? Strukturnaya Diagnostika offers a 12-month hardware warranty, on-site commissioning, operator training, recalibration services, and ongoing application support through their technical team.
