Material Testing

FTIR, Water Retention, Gurley Porosity, and Surface Tension

SNP offers material testing and has the capability of evaluating a wide range of materials, from paper to polymers, identifying contaminants, and general physical properties. See a small sampling of our capabilities below, as well as some of the top-of-the-line equipment we use in our testing. All work is strictly confidential, and we are fully prepared to perform your material testing under a signed confidentiality agreement. Call or email to discuss your specific materials testing needs!

FTIR

Fourier Transform Infrared Spectroscopy

Fourier Transform Infrared (FTIR) Spectroscopy is a measurement technique where infrared light is guided through an interferometer and through the sample. The interferogram, representing light output as a function of mirror position, is related to the IR spectrum by Fourier transformation.

This technique measures the types of bonds present in the test specimen.

STATIC AND DYNAMIC WATER RETENTION TESTS

Static and Dynamic Water Retention Tests

The water retention of coatings can be tested statically or dynamically. Water retention is an important characteristic of a coating because the rheology of the coating changes as free water leaves the coating and moves into the base sheet.

Gurley Porosity

Gurley testing measures the air resistance or porosity of paper, films, and related materials. This test helps determine how easily air passes through a material, which can be an important indicator of barrier performance, coating uniformity, and overall product quality.

SURFACE TENSION AND SURFACE ENERGY

Surface Tension and Surface Energy

Surface tension is the measurement of the amount of resistance the surface of a liquid has to the application of an external force. This is caused by the cohesion of molecules within the substance. In solids, this is described as surface energy, or the amount of energy per unit area.

CEM SOLID MOSITURE ANALYZER

CEM Solid Moisture Analyzer at SNP Inc.
Testing Service

CEM Solid Moisture Analyzer

SNP uses a CEM Smart 6™ Microwave and Infrared Moisture and Solids Analyzer. It is one of the most technologically advanced rapid moisture and solids analyzers available. The system features two major benefits compared to other moisture analyzers: the ability to accurately analyze both wet and dry samples and a significant reduction in sample drying times.

The combination of microwave and infrared energies allows any sample to be analyzed on one system without sacrificing accuracy or precision. The CEM Smart 6™ features include:

  • Direct loss on drying measurement
  • Up to ten times faster than halogen systems
  • Analyze wet and dry products on one system
  • Meets various AOAC requirements
  • Title 21 CFR Part 11 compliant
