Using Light To Unlock Secrets: The Definitive Guide To FTIR Testing

August 19th, 2011


FTIR TestingCompanies in industries across the board are searching for ways to understand material composition, provide better quality control of their products and identify materials and contaminants. FTIR Testing (Fourier Transform Infrared Spectroscopy, a technology using absorbance  infrared radiation makes all this possible.

 What is FTIR Testing?

FTIR Testing is an analytical technique used to identify organic and some inorganic materials.  Samples can be identified through the application of infrared radiation (IR).  As the sample absorbs the infrared light, the absorbance of energy at the various wavelengths is measured to determine the material’s molecular composition and structure.

Uses For Differential Scanning Calorimetry

February 25th, 2011


Differential scanning calorimetry is a process widely used for both quality testing and research in different industries. DSC is a technique to measure the difference in heat required to increase the temperature of a sample versus a known reference sample.

Using this technique, researchers and testers are able to gather critical data before, during and after creation of different products for industries including the pharmaceutical industry, food science and more.

To understand this process and what it does for different industries, let’s take a look at three industry examples for Differential Scanning Calorimetry:

Auger Electron Spectroscopy to Uphold Product Quality and Safety

January 10th, 2011


Auger Electron Spectroscopy To understand the composition of surfaces or interfaces of a particular product, manufacturers may rely on an analytical technique called: Auger Electron Spectroscopy.

This information is important to product manufacturers as it tells the story behind product contaminations, stains and passivation layers. With this information, solutions to these problems become available. This ensures the quality of the product and upholds the safety of their customers.

To understand the overall Auger Electron Spectroscopy process and how it helps manufactured product production, before and after, please refer to the following:

Ensuring Product Cleanliness with Ion Chromatography

December 21st, 2010


Testing the cleanliness of a product after the manufacturing process is critical. Ensuring a product is free from deposits and other contaminants insures quality and fewer complications when products ship out to market.

To guarantee the ionic cleanliness of products after manufacturing, a process called Ion Chromatography can be employed. This analytic process measures the levels of anions and cations present on a product   to make certain it meets specified requirements

To understand the IC process and how it helps products after the manufacturing process, consider the following information:

Using GC/MS to Analyze Unknown Compounds In Manufacturing

December 1st, 2010


Gas Chromatography

During the manufacturing process unknown compounds may be left in a product.  GC/MS is used by manufacturers to detect residual solvents trapped in a product either from the production line or cleaning process, trace levels of impurities in liquids, or atmospheric impurities in a sealed environment.

The detection of these foreign compounds left behind may be vital for manufacturers demanding the quality of their products and the safety of their customers.

A successful technique to discover these types of compounds is combining the features of gas chromatography and mass spectrometry. This process allows for the identification and quantification of many organic compounds left behind after the manufacturing process.

Using ESCA for Chemical Analysis of Stainless Steel

November 1st, 2010




The resistance of stainless steels to rust or corrosion is accomplished by passivation of the alloy to create a chromium-rich oxide layer.  The ESCA technique is an excellent tool to monitor the quality of the stainless steel passivation layer.

To understand the overall ESCA method and how it helps manufacturing needs, please refer to the following:

Electron Spectroscopy for Chemical Analysis of Stainless Steel

Many industries use stainless steel in manufacturing tools, instruments and products. During the manufacturing process, passivation or obtaining a chromium rich layer on the surface of the steel is required to ensure the surface is inert or non-reactive. This keeps the steel from developing corrosion or rust on the surface.
