Measurement Team

Materials measurement outputs defined values for various properties of materials—an example of this is an analytical balance, which outputs a numerical mass. The Measurement Team conducts testing for tensile and compressive strength, microhardness, contact angle measurement, UV-Vis spectroscopy, and thermal properties.

The Measurement Team is led by Seneca Stevens. Please contact Seneca for more information!


Equipment List:

SOP: Mark-10 ESM303 Mechanical Tester

Wiki: Mechanical Tester

The Mark-10 ESM303 is a single column mechanical testing frame capable of measurement applications up to 1.5 kN. It uses tensile, compression, cyclic loading, 3-point bending, and peel tests to quantify the stiffness, ultimate tensile strength, toughness, strength, ductility, and brittleness of your samples.

Instron Mechanical Tester

Located in Main Lab (169)

SOP: Instron 5967 Mechanical Tester

Wiki: Mechanical Tester

The Instron 5967 is a dual column mechanical testing frame made capable of measurements up to 30 kN. performing custom tensile, compression, 3-point bending tests. Various grips are located on the shelf adjacent to the testing frame.

The Instron 5967 has a max travel distance of 1.212 m (47.7 in) and max width of 0.418 m. For more specifications, see our SOP and Wiki pages.

Microhardness Tester

Located in Main Lab (169)

SOP: LECO LM248AT Microhardness Tester

Wiki: Microhardness Tester

Video: User Tutorial

The LECO LM248AT is a microhardness tester that can measure the Knoop and Vickers hardness of a material in local areas. This allows the user to understand how the microhardness of a material varies across different microstructural phases or surface layers. The measured hardness values can then be compared to industry standards to quantify the hardness of the material.

The microhardness tester features 10x and 50x objectives along with Knoop and Vickers indenters. For more specifications, see our SOP and Wiki pages.

DSC

Located in Main Lab (176)

SOP: Linseis Chip-DSC 10

Wiki: Differential Scanning Calorimeter (DSC)

Differential scanning calorimetry (DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. It allows for rapid cooling rates without active cooling and can identify crystallization temperatures, enthalpies of transformation, phase transitions, and heat capacities. The Linseis Chip-DSC 10 sensor is calibrated based on the known melting points and latent heats of fusion of In, Sn, Pb, and Zn.

For specifications, see our SOP and Wiki pages.

TGA

Located in Main Lab (176)

SOP: Coming soon!

Wiki: Thermogravimetric Analyzer (TGA)

A thermogravimetric analyzer (TGA) uses heat to force reactions and physical changes in materials, and provides quantitative measurements of mass change associated with transition and thermal degradation. TGA records changes in a sample’s mass from the dehydration, decomposition, and oxidation of a sample against changes in time and temperature. The characteristic thermogravimetric curves of materials and chemical compounds are given by unique sequences of physicochemical reactions, which occur at specific temperature ranges and heating rates depending on the sample’s molecular structure.

For specifications, see our SOP and Wiki pages.

Moisture Analyzer

Located in Main Lab (176)

SOP: OHAUS MB120 Moisture Analyzer

Wiki: Moisture Analyzer

The OHAUS MB120 Moisture Analyzer measures moisture content in liquid, paste, and solid materials by utilizing a loss on drying (LOD) method. The moisture analyzer weighs a sample, heats it up to dry it, and weighs it again once it’s dry. The weight after drying is subtracted from the weight before and the original moisture content is determined using the difference in mass.

The OHAUS MB120 has a mass range of 0.5 – 120 g with 0.1 mg precision. For more specifications, see our SOP and Wiki pages.

IR Camera

Located in Main Lab (176)

SOP: FLIR ETS320 Infrared Camera

Wiki: Infrared Camera

The FLIR ETS320 Infrared Camera is used for imaging heat transfer in electronic components and monitoring the progress of chemical reactions. Infrared cameras are used for thermal imaging and display the surface temperature of objects in a heat map. It only takes about one-thirtieth of a second for the detector array to obtain the temperature information to make the thermogram, and this information is obtained from several thousand points in the field of view of the detector array.

For specifications, see our SOP and Wiki pages.

UV-Vis Spectrophotometer

Located in Main Lab (176)

SOP: Avantes UV-Vis Spectrophotometer

Wiki: UV-Vis Spectrophotometer

The Avantes UV-Vis Spectrophotometer allows you to measure the reflection, irradiance, transmission, and absorption spectra of materials. It has three different source setups to accommodate liquid, powder, and solid samples. It can measure peak absorbance wavelengths and perform colorimetry experiments. PMMA and quartz cuvettes are available for solution testing.

For specifications, see our SOP and Wiki pages.

Contact Angle Goniometer

Located in Main Lab (169)

SOP: ramé-hart Contact Angle Goniometer

Wiki: Contact Angle Goniometer

The ramé-hart Contact Angle Goniometer (model 210) is primarily used to measure the contact angle of water and other liquids, which is defined as the angle formed by a liquid when in contact with a solid surface. The instrument uses DROPimage Pro software to determine the contact angle from the shadow image of the drop placed on the stage.

For specifications, see our SOP and Wiki pages.

Analytical Balance

Located in Main Lab (176) & Ceramics Lab (369)

SOP: VWR Analytical Balance (includes Archimedes method)

Wiki: Analytical Balance

Analytical balances provide the best weighing performance and are used for the accurate weighing of samples and precipitates. They are a class of balance designed to measure small masses in the sub-milligram range to high precision, accounting for temperature and humidity correction. VWR’s balances can be used for density determination by Archimedes method and for mass over time measurements.

The VWR-164AC mass a mass range of 10 mg – 160 g with 0.1 mg precision. For more specifications, see our SOP and Wiki pages.
