Combining LIBS & Raman

Unlocking the Secrets of Molecules with LTB’s Raman Spectroscopy Solutions

For a multitude of scientific research and industrial applications, the ability to analyse and comprehend the fundamental properties of molecules is absolutely crucial. At LTB Lasertechnik Berlin GmbH, we are proud to offer cutting-edge Raman Spectroscopy solutions, a powerful analytical technique that has proven to be an invaluable tool for these challenges. Our advanced systems empower scientists to investigate the vibrational and rotational modes of molecules, providing profound information about their chemical composition, intricate structure, and dynamic behaviour.

Raman spectroscopy is a non-destructive optical technique based on the interaction of light with matter. It harnesses the Raman effect, discovered by Indian physicist Sir C.V. Raman in 1928. This effect occurs when incident photons interact with molecules, causing them to scatter photons at different wavelengths. The difference in wavelength between the incident and scattered photons – known as the Raman shift – is directly proportional to the vibrational energy of the molecule, providing a unique spectral fingerprint.

Raman spectroscopy, supported by LTB’s precision instrumentation, has found extensive use across various sectors. The true power however can be found when paired with LIBS.

For truly exhaustive material characterisation, a single analytical technique often tells only part of the story. At LTB Lasertechnik Berlin, we understand that deeper insights come from combining powerful methods. That’s why we champion the synergistic pairing of Laser-Induced Breakdown Spectroscopy (LIBS) and Raman Spectroscopy, offering you the capability to unlock both the elemental and molecular secrets of your samples with unparalleled precision.

Our advanced LIBS solutions excel at rapid, real-time elemental analysis. By focusing a high-energy laser pulse onto a sample, LIBS generates a micro-plasma whose emitted light reveals the unique elemental fingerprint of the material. This technique is superb for rapid elemental identification, quantitative elemental analysis, fast screening with the added benefit of minimal sample preparation. This way solids, liquids, and gases can be analysed with little to no pre-treatment.

Complementing LIBS, our cutting-edge Raman Spectroscopy solutions delve into the molecular world. Raman spectroscopy interacts with molecules to reveal their vibrational and rotational modes, providing invaluable information about chemical structure and bonding, phase identification (amorphous or crystalline) structures, stress & strain analysis, non-destructive analysis and high spatial resolution for sample mapping.

Why Combine LIBS and Raman?

While LIBS tells you what elements are present, Raman tells you how those elements are bonded together and what molecules they form. This combined approach delivers a complete picture, making it indispensable for complex analytical challenges such as material characterisation, forensics, quality control and technical cleanliness analysis.

Imagine analysing a painted artefact: LIBS can identify the inorganic pigments (e.g., lead, iron), while Raman can tell you the specific molecular compounds of those pigments (e.g., lead white, iron oxide) and even identify organic binders. This dual insight provides an unparalleled understanding.

At LTB, we are uniquely positioned to provide robust solutions for both LIBS and Raman spectroscopy. Our expertise in developing high-performance Echelle spectrometers and precision laser systems ensures that whether you choose a standalone LIBS or Raman system, or opt for an integrated solution, you receive the highest quality data. We understand the nuances of each technique and how they can be leveraged together to overcome complex analytical hurdles.
