Equipment And Resources
Nuclear magnetic resonance (NMR) spectroscopy is a nondestructive analytical technique used to identify or confirm chemical structures of organic molecules. A sample is placed into a magnetic field which excites nuclei in a molecule and causes them to emit electromagnetic radiation. This radiation occurs at a specific resonance frequency which is highly characteristic for different functional groups in the molecule. Typically, NMR spectrometers have a large footprint and require cooling of the magnet with liquid helium or other cryogens. This benchtop model is ideal for a research environment because it requires very little maintenance and operates without the use of expensive cryogens, while still providing high-resolution H1 NMR spectra.
Formlabs Form 2 SLA 3D Printers
A stereolithography apparatus (SLA) is a type of 3D printer that produces parts layer by layer using photopolymerization. Structures can be produced quickly and with a variety of different resins to suit specific applications.
TA Instruments Discovery Hybrid Rheometer DHR-2
A rheometer measures the way a fluid responds to an applied force and is used by polymer scientists to understand the flow and deformation effects of a material. Common uses include the characterization of material properties such as viscosity, storage modulus, and loss modulus. The DHR-2 comes equipped with a UV power source so resins can be UV-cured into polymers while monitoring various rheological parameters.
TA Instruments Thermogravimetric Analyzer 550
Thermogravimetric Analysis (TGA) measures the mass of a substance as a function of temperature or time in order to provide information about vaporization, sublimation, oxidation, decomposition and other properties. It consists of a sample pan that resides in a furnace and is weighed by a precise balance as the temperature of the furnace is changed over the course of the experiment. TGA can be used both for chemical analysis and for evaluation of polymeric materials.
TA Instruments Differential Scanning Calorimeter 2500
Differential scanning calorimetry (DSC) calculates the heat flow into or out of a material by measuring the temperature difference between a sample pan and an empty reference pan being heated under identical conditions. Thermal transitions that can be measured by TA Instruments’ DSC techniques include glass transitions, “cold” crystallization, phase changes, melting, crystallization, product stability, cure kinetics and oxidative stability. This model also has the ability to perform modulated DSC for monitoring more complex transitions.
TA Instruments Dynamic Mechanical Analyzer Q800
Dynamic mechanical analysis (DMA) is a technique used to study the viscoelastic behavior of materials. A sinusoidal deformation is applied to a sample and the material’s response to stress, temperature, frequency or other values is studied. This approach can be used to locate the glass transition temperature of the material, as well as to identify transitions corresponding to other molecular motions.
Waters ACQUITY Advanced Polymer Chromatography System
The Advanced Polymer Chromatography (APC) system is able to characterize low to mid range molecular weight polymers using size-based analysis. The APC works faster than GPC and brings high accuracy to low molecular weight polymer analysis.
Waters Gel Permeation Chromatography System
Gel permeation chromatography (GPC) is a separations technique based on size differences between molecules. The sample is passed through columns containing packing materials of different pore sizes. The smaller molecules are caught by the pores while the larger molecules pass through without being impeded. The larger molecules are therefore detected earlier in a run while the smallest molecules are separated and detected last. This system includes the Waters 2695 Separations Module, the Waters 996 Photodiode Array Detector and the Waters 2414 Refractive Index Detector.
Grace Reveleris (R) X2 Flash Chromatography System
Liquid chromatography is a separation technique based on solvent and compound polarity. A stationary phase (typically highly polar silica gel) binds to the molecules that pass through with a strength relative to their own polarity. A solvent mixture is run through the column to move the applied compound through the column, achieving separation based on relative polarities in the process. The Grace Reveleris comes equipped with integrated UV/Vis and ELSD detection capabilities to identify a range of UV active and inactive compounds.
Thermo Scientific (TM) Nicolet (TM) iS (TM) 50 FTIR
Fourier-Transform Infrared Spectroscopy (FTIR) is a technique that uses infrared light to obtain absorption or emission spectra of a solid, liquid, or gas. Infrared light is passed through or reflected off of a sample and the instrument detects how much of the light has passed through the material. It is a simple, fast, and reliable way of identifying the presence or concentration of a compound. This model has both near-IR and mid-IR capabilities in addition to a heating cell for temperature control, a temperature controlled gas cell and a polarizer.
Thermo Scientific (TM) Nicolet (TM) 6700 FTIR
Fourier-Transform Infrared Spectroscopy (FTIR) is a technique that uses infrared light to obtain absorption or emission spectra of a solid, liquid, or gas. Infrared light is passed through or reflected off of a sample and the instrument detects how much of the light has passed through the material. It is a simple, fast, and reliable way of identifying the presence or concentration of a compound. This model comes equipped with an ATR smart accessory and has mid-IR capability.
HORIBA XploRA (TM) Raman Spectrometer with Olympus BX41 Microscope
Raman Spectroscopy is a technique that observes vibrational and rotational modes in a system in order to provide a molecular fingerprint of the sample. It is similar to FTIR, however, the two do differ. Raman spectroscopy measures relative frequencies at which a sample scatters radiation, unlike IR spectroscopy which measures absolute frequencies at which a sample absorbs radiation.
The Instron is an instrument used to test material properties by applying a load to the material. The various tests that the Instron can perform are compression, tensile, flexural, fatigue, impact, dynamic, torsional and multi-axial loading. The Instron does this with an interchangeable load cell and interchangeable mounting systems for the materials.
