Sample Introduction - Nebulizers

Posted by Manny Almeida on Apr 28, 2022 11:37:34 AM

For most applications, the ICP-OES requires the sample be in liquid form. Solid samples can be acid digested or dissolved in a solvent suitable for use with the ICP.

Liquid samples are delivered to the ICP using a sample introduction system, which is made up by the torch, spray chamber, nebulizer, peristaltic pump and tubing. In this blog post, we will look at the nebulizer.

Are you considering purchasing an ICP - here is a guide to help in selecting the right ICP for your needs.

Posted by Teledyne Leeman Labs on Jul 25, 2019 3:27:35 PM

Selecting the right ICP requires consideration of analytical requirements, available technologies, manufacturer specific features and benefits, estimation of current and future sample loads (as well as the number of
elements determined), warranty and service offerings, and instrument cost vs return on investment (including the cost of analysis). While it can be difficult to navigate industry terminology, the answer to what ICP fits your needs, is not difficult to determine.

Food Sleuths Seek Out Bogus Ingredients, Bad Pathogens and Imposter Foods

Posted by Betsey Seibel on Oct 3, 2016 1:01:27 PM

With millions of consumers reportedly getting sick each year from foodborne diseases, how do food analysts know the best methods to keep products safe, manage risk and protect the integrity of their brands?  With the variety of methods available in the battle of food defense, food safety experts have to carefully hone their choices. A recent article in Lab Manager magazine went into more detail about a few of these methods.

Heavy Metals in Reagent Chemicals

Posted by Betsey Seibel on Aug 30, 2016 2:27:59 PM

When it comes to analytical testing, there is a single organization that sets the requirements and develops the methods for determining the purity of reagent chemicals, the American Chemical Society (ACS).


Teledyne Leeman Labs recently completed an analysis of reagent chemicals to determine their ultratrace elemental levels. The purpose of the analysis was to “demonstrate the ability of the Teledyne Leeman Lab’s Prodigy7 simultaneous ICP-OES, to quickly and accurately determine ultratrace elemental levels in selected reagent grade chemicals.” The company performed the analysis using procedures developed by the ACS. Results were then compared with ACS specifications.

Introducing the Prodigy Plus Inductively Coupled Plasma – Optical Emission Spectrometer

Posted by Betsey Seibel on Jul 20, 2016 3:05:55 PM

Leeman Labs is a pioneer in the ICP spectrometry industry, and we were the first to use an Echelle spectrometer for ICP-OES. Recently we added our new Prodigy Plus High Dispersion ICP Spectrometer to our family of ICP-OES instruments. The Prodigy Plus builds upon our legacy and experience, while incorporating new state-of-the-art technology.

Using Teledyne Leeman Labs Prodigy7 ICP-OES for Analysis of Petroleum Samples

Posted by Betsey Seibel on Nov 5, 2015 3:26:27 PM

Since the 1970s, petrochemical labs have used Inductively Coupled Plasma - Optical Emission Spectroscopy (ICP-OES) as a key technique to determine a range of elements and concentrations in both aqueous and organic samples. ICP is compatible with a variety of organic solvents, which means it permits the preparation of a broad range of sample types using a simple dilution.

Alloying Elements in High-Carbon Steel

Posted by Betsey Seibel on Aug 13, 2015 1:42:00 PM

Steel is critical to our modern world, with companies producing more than 1.6 billion tons every year[i]. When it comes to high-carbon steel, the higher the carbon content, the harder and stronger the steel is.  As carbon is reduced, the iron becomes more flexible and easier to form. Carbon steel makes up more than 85% of the steel produced in the United States, and while other alloys can be used to change steel properties, such as Manganese and Vanadium, carbon is the most cost-effective alloying material for iron.

Teledyne Leeman Labs: A Historical Perspective

Posted by Jason Davis on Mar 20, 2015 4:08:59 PM

History of Teledyne Leeman Labs

OldLeemanLabsInclogoIn 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.

PS950ICPOESThis 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.

Evolution of ICP, Part IV – 2000 to Present

Posted by Betsey Seibel on Feb 10, 2015 1:10:00 PM

The instruments being marketed today have reached a level of sophistication that would not have seemed possible 40 years ago. Though the fundamental principles of the technique have not changed, the technology has seen significant advancements, especially in the design of the ICP source, optical spectrometer and detection systems. Simultaneously, milestones in real-time elemental coverage, sample throughput and ease-of-use, continue to make it easier to reach new pinnacles in productivity and data quality.
