Total organic carbon analyzer explained: how it measures water purity and detects organic contamination accurately.
A Laser Ablation System is an analytical instrument that uses a focused laser beam to remove (ablate) microscopic amounts of material from a solid sample for chemical, elemental, or isotopic analysis.
The ablated material is converted into an aerosol and typically transported to an analytical detector such as:
Laser ablation is widely used because it enables direct solid sampling with high spatial resolution and minimal sample preparation.
The IRIDIA Ultimate Elemental Imaging Laser Ablation System is a purpose-built laser ablation platform designed to deliver fast, high-precision elemental imaging and solid sampling for analytical laboratories. It’s engineered to make complex laser ablation ICP-MS workflows easier to set up and faster to run, enabling high throughput and reproducible results
The new Iridia is a purpose-built laser ablation system designed for high-speed imaging applications that can take your overnight projects and complete them in minutes. Iridia produces high stability laser energy at higher speeds to make full use of the latest ICP-MS technology. The Cobalt sample cell offers single millisecond analytical performance. Iridia features a 500 Hz ATL laser, custom-designed for Teledyne Photon Machines to give ultimate reliability and performance, backed by a two year warranty and a 1 billion shot guarantee. The integrated, fully enclosed and actively vented gas cabinet holds all the necessary excimer premix and helium gas bottles. The patented ExiCheck gas exchanger automatically exchanges the ArF gas on a pre-set interval with no
user interaction required.
A wide variety of commercially available sample cups are supported to achieve maximum productivity and to ensure compatibility with your lab’s digestion vessels
A laser ablation system uses a focused laser to remove microscopic material from solid samples, enabling high-resolution elemental and isotopic analysis. When coupled with analytical instruments such as ICP-MS, it allows direct solid sampling, minimal preparation, preserved spatial context, and precise elemental imaging across a wide range of scientific applications.
IRIDIA is designed for high-resolution elemental and isotopic imaging of solid samples when coupled with ICP-MS. It is commonly used in geoscience, materials science, environmental research, life sciences, and forensics to visualise elemental distribution at the micrometre scale.
IRIDIA stands out due to its 193 nm excimer laser, ultra-fast washout Cobalt sample cell, and high repetition rates (up to 1 kHz). These features enable faster imaging, improved spatial resolution, and reduced signal dispersion compared with many Nd:YAG-based systems.
IRIDIA uses a 193 nm ArF excimer laser, which offers:
This makes it ideal for precision imaging applications.
IRIDIA supports spot sizes from approximately 1 µm up to ~210 µm, allowing both ultra-fine elemental mapping and bulk analysis within the same platform.
IRIDIA supports a wide range of samples, including:
Thanks to its high repetition rate (up to 1 kHz) and fast washout sample cell, IRIDIA significantly reduces acquisition time, making it well-suited for large-area, high-density elemental maps.
IRIDIA is operated using Chromium software (with HDIP imaging tools), which provides:
Key design elements such as the patented Cobalt sample cell, dynamic Z-control, and dual attenuators help ensure:
IRIDIA is ideal for laboratories that require:
This includes academic institutions, national labs, and industrial R&D facilities.
Yes. When properly calibrated with matrix-matched standards, IRIDIA supports quantitative and semi-quantitative elemental analysis, in addition to qualitative imaging.
