Company Description
Since its founding in 1981, Teledyne Leeman Labs has been an innovator in atomic spectroscopy and introduced many concepts that are now considered industry standards. Among these was the first use of an Echelle spectrometer and the first fully automated mercury analyzer. As a leading supplier of instruments for elemental analysis, we take great pride in the quality and value of our products and the depth of our commitment to our customers.
Chief Spectroscopic Techniques Supported
- Inductively coupled plasma (ICP) spectrometers
- DC Arc spectrometers
- Mercury analysis of liquids, solids, and semi solids via cold vapor atomic absorption or atomic fluorescence
Markets Served
Teledyne Leeman Lab's products are used in applications essential to QA/QC, environmental analysis, research and development, and commercial production. They are used in many industries including: aerospace, agriculture, automotive, beverage, biofuels, electronics, energy, environmental and contract labs, gas, food and food processing, forensics, geological, metals production, mining, nuclear, petrochemical, petroleum, pharmaceutical, wastewater, and wear metals and oils.
Major Products/Services
Inductively Coupled Plasma Spectrometers (ICP): Prodigy ICP line is our most powerful and versatile ICP spectrometer. It brings together a state of the art large format, programmable array detector (L-PAD) with an advanced high dispersion Echelle spectrometer to provide exceptional analytical performance.
Mercury Analysis: The Hydra II AA and C and QuickTrace™ 7600 and 8000 automated mercury analyzers operate on the principle of cold vapor atomic absorption (CVAAS) spectrometry or atomic fluorescence (CVAFS). The analyzers are used for the determination of mercury in a wide variety of liquid sample matrices including water, wastewater, urine, and blood. They can also be used to perform the direct analysis of mercury in solids and semi-solids such as soils, sludges, powders, foods without any sample preparation.
DC Arc Spectrometer: The Prodigy DC Arc spectrometer is specially designed for fast, quantitative analysis of elements in samples that are difficult, if not impossible, to dissolve or digest such as high purity metals. The Prodigy DC Arc analyzes elements at low to trace levels (sub ppm) in native solid materials without the need for time consuming, labor intensive sample preparation.
Facility
Teledyne Leeman Labs is located in Hudson, New Hampshire (40 min from Boston). Our facilities include both product demonstration and customer training laboratories. We have a global network of sales, technical specialists, and service personnel to provide high responsive support for all of your needs.

In this Q&A article, we highlight several prominent researchers being recognized at the 2026 SciX Conference for their significant contributions to spectroscopy and photonics and discuss what these researchers talked about at the conference.
Amy Colleran, a Postdoctoral Researcher in the Centre of Metabolomics Research at the University of Liverpool, is exploring how to detect volatile organic compounds by bubbling them directly into colloidal silver and gold nanoparticles.
The Eastern Analytical Symposium returns to Plainsboro, New Jersey, November 16–18, with a keynote on AI-ready data and a posthumous award honoring solid-state NMR researcher Robert Schurko.
In this segment of our SciX interview with Kevin Wilkinson, a professor of environmental chemistry at the Université de Montréal, discusses extending lead isotope work to greater distances and explains why graduate students need adaptability, critical judgment, and coding skills more than expertise in any single instrument.
Atomic spectroscopy has quietly gone from counting elements in bulk to counting single nanoparticles, imaging tissue at the micrometer scale, and reading Martian rocks from several meters away. The instruments got smaller, the software got smarter, and the questions they can now answer got a lot more interesting.
