Formally confirming that your products and services meet all trusted external and internal standards. Search all products by. Materials with similar organic bonds but different molecular weights such as hydrocarbon oil, paraffin wax, low density polyethylene, and high density polyethylene can have similar spectra.
This results in an FTIR spectrum without the minute details necessary to identify the unknown material. Standards can be obtained from appropriate standards authorities. The amount of contamination that can be detected depends on the spectral scans of the base polymer and the contaminant.

A spectral scan of a reference material can be generated and stored in a spectral library database. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. You may experience issues viewing this site in Internet Explorer 9, 10 or Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
adtm FTIR can identify the difference between materials, such as polypropylene and polyethylene, which are made of only carbon and hydrogen but have different types of bonds between the elements.
Certification Formally confirming that your products and services meet all trusted external and internal standards. If the material does not absorb infrared light a spectral scan cannot be obtained. You may find similar items within these categories by selecting from the choices below:. FTIR spectral subtractions are used to look for internal contamination in polymers.
A solvent wash involves using a solvent that is nondestructive to the sample. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Assurance Testing Inspection Certification.
Computer matching programs have difficulties with subtle differences that can be critically important. Material testing you can trust since Find Similar Items This product falls into the following categories. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. The objective is to look for material differences. Identify the primary component of a plastic, rubber, or organic material. This instrument transmits an infrared light through a sample and varies the wavelength of the light as it records how much light is absorbed at each wavelength.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. FTIR is also used for quality control of materials and for contamination analysis surface or internal.
Fourier Transform Infrared Spectrometry ASTM E, ASTM E
The better the match, the higher the certainty for a correct identification asgm the unknown polymer. However, an FTIR spectral scan alone should not be expected to identify the type of Nylon or Polyester, identify a Polypropylene or Acetal as a homopolymer or copolymer, or determine whether the Polyethylene is a high density or low density material.
Further identification may be aided by DSC. Your basket is empty. A skilled FTIR analyst is needed to examine the computer selected spectral matches to ensure that sample identifications are both accurate and complete. Take the smart route to manage medical device compliance. Poor at identifying minor components in mixtures or finding trace additives unless they can be separated prior to analysis.
