Purpose: To measure epoxy value and starting liquid resin content with the two-probe Simulplex™ ChemView® photometer and fiber optic insertion probes with simple, easy-to-maintain, linear calibrations. Approach: The NIR peak at 2208 nm is traditionally used to measure epoxy value. However, this intense peak requires a narrow optical narrow path (2 mm). Also, the basic liquid resin starting material is a spectral interferent, requiring more sophisticated (multivariate) calibration methods. The Optical Solutions’ PS-2 diode array spectrometer was used to measure the NIR spectra of 13 samples at 190°C in a 5 mm cuvette in the HeaterCell™ fiber optic accessory. Products & Services
Molding compounds and resins are industrial plastics and polymers that are suitable for forming. They are available as pellets, liquids, and powders and are used in processes such as injection molding, compression molding, reaction injection molding (RIM), resin transfer molding (RTM), and blow molding.
Conductive adhesives and compounds provide an electrically and/or thermally conductive path between components.
Electrical resins and electronic compounds includes adhesives, greases, pads, stock shapes, tapes, encapsulants, potting compounds, thermal interface materials, and electrically conductive substances used in electrical, electronics, and semiconductor applications.
Spectrometers are analytical instruments which disperse an emission (such as particles or radiation) according to some property of the emission (such as mass or energy) in order to measure the amount of the dispersion. This product area includes visible, infrared (IR), ultraviolet (UV), atomic absorption (AA), optical emission (OE), Raman, X-ray fluorescence (XRF) and mass spectrometers. Specific search forms are also available.
Flame photometers use atomic emission for the routine detection of metal salts, principally sodium (Na), potassium (K), lithium (Li) and calcium (Ca).
