Our Brands | Teledyne LABS

In 1981 John R. Leeman and Karl Hildebrand founded Leeman Labs to produce analytical instrumentation based on the promise of Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES) [also referred to as Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES)] to identify and quantify the concentration of elements within a sample. This initial success established Leeman Labs as both an innovator and an expert in ICP-OES and lead the company to endeavor into other realms of atomic spectroscopy adding the DC Arc technique and Mercury Analysis to its line of analytical instrumentation. In 2004 Leeman Labs was acquired by Teledyne technologies to augment Teledyne's existing laboratory and continuous monitoring instruments used in environmental applications, and complement Teledyne Tekmar's organic analysis instrumentation.

Today, its instruments can be found conducting analyses across a broad spectrum of industries and sample types. The usefulness of Teledyne Leeman Lab's elemental analysis instrumentation ranges from agriculture to aerospace and forensics to food in over 50 countries.

The history of Teledyne Leeman Labs is filled with "firsts" in Atomic Spectroscopy. But the past is not only about revolutionary moments, it is also about refinement. It's easy to discern from the timeline of Teledyne Leeman Labs historic milestones, that we have always maintained a balance of innovation and refinement. Over the years the path to excellence in atomic spectroscopy has always led to Teledyne Leeman Labs, and still does.

2000-2009

2009 - Introduction of the Hydra II Mercury Analyzer series. Building on the strengths of the original Hydra series, this versatile product line currently includes: The Hydra IIAA - A fully automated Mercury Analyzer based on the traditional Cold Vapor Atomic Absorption (CVAA) technique to address a host of applications such as mercury in soils, sludge, tissues, blood, wastewaters, drinking waters, and more. The Hydra AA typically yields limits of detection in the 1 to 2 ppt range. The DC Arc Spectrometer is developed in response to customer request. Teledyne Leeman Labs developed the DC Arc instrument to offer fast, quantitative, elemental analyses of difficult samples. The hallmark of the DC Arc technique is the ability to analyze samples that are difficult or impossible to digest. With high sensitivity and simple operation, the DC Arc is capable of performing elemental analysis of samples in their native form without sample digestion.
2007 - Hydra C Mercury Analyzer was introduced. They Hydra C is a fully automated Mercury Analyzer capable of measuring mercury in solid and semi-solid sample matrices without acid digestion. The Hydra C uses sample combustion (thermal decomposition), mercury concentration via gold amalgamation, and detection by Cold Vapor Atomic Absorption (CVAA). The Hydra C has the unique advantage of eliminating the sample preparation and hazardous waste associated with conventional mercury techniques. The product set the stage for the Hydra II family. The Hydra C was renamed the Hydra IIC in 2009.
2006 - Introduction of the Prodigy-H ICP. The Prodigy H permitted the measurement of halogen elements as well as more routine metal analysis. Historically, the determination of halogen elements required alternative analytical techniques such as ion chromatography or ion selective electrodes. This new frontier was made possible due to advancements in ICP-OES spectrometer and detector designs resulting in increased wavelength sensitivity. Teledyne Leeman Labs adds Time Resolved Analysis (TRA), broadening its instrument capabilities. Both the Prodigy ICP and Prodigy DC Arc incorporated modes giving them the ability to acquire elemental data on an intensity versus time basis. Applications include element specific chromatographic separations (e.g., differentiating between Cr, Cr III and Cr VI) and spatially resolved laser ablation experiments (e.g., depth profiling and/or linear traverses across a sample).
2005 - Prodigy XP ICP was introduced. The Prodigy XP accomplished a shorter wavelength range.
2004 - The introduction of the UP266 MACRO Laser Ablation System. Laser ablation was first investigated in the early 1960s and explored further 25 years later using ICP-MS. Teledyne Leeman Labs specifically designed this system for use with both ICP-OES and ICP-MS. UP266 MACRO offers a wide variety of ablation methods such as spot ablation for depth profiling, line scanning for lateral analysis and raster scanning for bulk analysis. Leeman Labs is acquired by Teledyne Technologies.

The Analyte 16, which incorporated this new technology, was first introduced by Analyte Corporation of Medford, Oregon, and was developed using a new optical spectroscopy technique called AtomSource Atomic Absorption. The technique, based on Glow Discharge, was a major breakthrough in optical spectroscopy for the direct analysis of solid samples by Atomic Absorption (AA). Introduction of the first Data Acquisition System for ICP-OES with unlimited autoranging capability. This advancement matched the data system to the capability of the ICP. Developed the first unique RF drive electronics capable of boosting the output of hollow cathode lamps. This resulted in both high-light flux and longer lamp life.
1993 - The first Transportable ICP, the PS-Series Mobile, was introduced for efficient, on-site analysis. The PS-Series Mobile was engineered to withstand the rigors of in-field operation, without sacrificing laboratory quality data. The benefits of a transportable ICP included onsite analysis on both land and at sea, rapid results to guide site characterization and/or remediation efforts, rapid metals analysis at the research site, pollution source, or spill site.
1996 - Introduction of the Direct Reading Echelle (DRE) ICP Detection System. In addition to the features of its predecessors, the DRE ICP could be configured in any viewing mode (i.e., radial, axial or dual view) for superior analytical performance and significant minimization of interferences.
1992 - The first Automated Mercury Sample Preparation System, the AP 200, is introduced. The AP 200 automated all aspects of Mercury Analysis sample preparation. This automation reduced the time and labor associated with sample preparation, and eliminated the uncertainty associated with missed spikes and/or reagent additions. The first Automated Cyanide Analysis System, the PS 1214, is introduced.

The PS series was available in automated sequential, simultaneous, or combination Sim/Seq Echelle-based ICP. After years of continual ICP refinement the PS Series was an impressive milestone, possessing fully automated control of all operating parameters.
1987 - The "Flagg Oscillator", the first 40 MHz Free Running Oscillator, was introduced. The oscillator was a highly efficient, user-friendly ICP source. This ICP generator simplified the plasma ignition process and had very high-speed impedance mismatching capability. This simplified operation when analyzing complex matrices such as organic solvents. The Plasma-Pure Standards Product Line is introduced, including single and custom multi-element inorganic standards for the analytical marketplace.
1986 - The Hildebrand Nebulizer, designed to resist clogging by solutions containing high levels of dissolved solids is introduced. Because this nebulizer produces a very fine, uniform aerosol, it yielded significant improvements in limits of detection and higher precision.
1983 - Leeman develops the first benchtop ICP, The Plasma-Spec. This instrument represented an unflinching departure from the conventional optical systems used in atomic spectroscopy. It was the first ICP to use an Echelle optical system, which gave it the highest resolution and dispersion of any commercially available ICP. It is interesting to note that today most ICP manufacturers have abandoned the more classical spectrometer designs in favor of Echelle-based systems similar to Leeman Labs first offering.
1981 - Leeman Labs is founded by John R. Leeman and Karl J. Hildebrand with the intention of producing analytical instrumentation based on new technological advancements in ICP-AES.
