Gas Adsorption Analysis
Gas Adsorption Analysis (Physisorption)
In Material Testing
please contact us for pricing

Gas Adsorption Analysis (also called Physisorption Analysis or BET Analysis) is a highly flexible and accurate technique for measuring specific surface area, pore sizes / size distribution, and overall porosity of solid samples as well as active metal area, dispersion and crystallite size for materials with gas-reactive surface like catalysts. These can impact electrical, physical, and thermal properties and affect overall performance of devices and systems. See also: Capillary Flow Porometry (or Porometry) is an alternative porosity measurement technique suited for permeable samples.

Gas Pycnometry
Gas Pycnometry (Pycnometry)
In Material Testing
Base Price: $180 per Sample

Gas Pycnometry is one of the most widely used techniques for analyzing true and skeletal density of any solid (even ones which are porous, granular, and irregularly shaped!). It provides fast, high accuracy volume measurements that can be used to calculate density and porosity, and can be adapted to analyze purity, quality, volatile organic content, and stability of certain materials. Covalent uses an industry-leading Ultrapyc 5000 Gas Pycnometer from Anton Paar for true density analysis. This tool achieves best-in-class accuracy across the widest array of sample types, including coatings, polymer foams, cements, mining, pharmaceuticals, ceramics, catalysts, metallurgy and more.

Photoelectron Spectroscopy in Atmosphere
Photoelectron Spectroscopy in Atmosphere (PESA)
In Analytical Services,Material Testing
please contact us for pricing

Photoelectron Spectroscopy in Atmosphere (PESA) is a technique used to analyze the work function of a surface: i.e., the amount of energy needed to remove an electron from the sample. Work function is particularly important to measure as it can determine the efficiency and other key properties of junction contacts. It is a fundamental property for Schottky barrier devices used in many of our electronics. In addition to measuring the work function, PESA can also be used for certain samples to estimate the density of states (DoS), highest occupied molecular orbital (HOMO) energy level, lowest unoccupied molecular orbital (LUMO) energy level, band gap and energy gap.

Raman Microscopy
Raman Microscopy (Raman)
In Analytical Services,Chemical Composition,Material Property Analysis,Microscopy & Imaging
please contact us for pricing

Raman spectroscopy is a chemical analysis technique which probes the vibrational modes of compounds. It produces a spectrum which can provide fingerprint identification of materials when compared against a reference library of known standards.
