Molex, LLC is showcasing its new Polymicro Technologies™ nano-Capillary Tubing in booth 2333 at Pittcon 2016 Congress and Expo, which focuses on analytical chemistry and applied spectroscopy and will be held March 6-10 at the Georgia World Congress Center in Atlanta.

“Proven as a substrate for packaging integrity and leak testing, this capillary also offers the potential for single-molecule research and analysis. Diameter control is assured through SEM verification.”

The Polymicro Technologies nano-Capillary line features tubing with internal diameters (IDs) from 200 to 1,000nm (0.2 to 1.0μm). Traditional capillary tubing products do not offer IDs smaller than 1μm. Prior to the development of nano-Capillary tubing, the Scientific, Industrial and Medical communities leading options for sub-1 micrometer diameter substrates were wet-etch or ion-beam milling, both of which are expensive and relatively inaccessible.

“Building on industry-leading capabilities, Polymicro Technologies™ nano-Capillary tubing delivers cost-effective, high-performance capillary tubing in the sub-1 micrometer regime,” said Joe Macomber, separation science product manager, Molex. “Proven as a substrate for packaging integrity and leak testing, this capillary also offers the potential for single-molecule research and analysis. Diameter control is assured through SEM verification.”

Synthetic fused silica offers mirror-smooth interior surfaces that enable stable flow of liquids and gases. The material’s low metal ion content provides an inert inner surface and facilitates efficient cleaving or cutting for custom tubing lengths. In addition, a polyimide coating on the tubing exterior offers excellent abrasion resistance during handling and use and allows the tubing to be used in temperatures ranging from -65ºC to +350ºC.

Scientific applications include analytical chemistry, chromatographic techniques, nanofluidics, on-column monitoring, evanescence-based sensing, and coaxial-light and fluidic devices. Industrial applications include package leak testing, evaporative cooling systems, petroleum analysis, and catalytic research. Medical applications include drug delivery, flow-control systems, clinical and diagnostic devices and wearable drug delivery devices.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Combinatorial ChemistryCombinatorial chemistry, also known as combichem, is a technique used in drug discovery to create libraries of structurally related compounds. A library is generated by synthesis with a chemical reactor system or by computer-based modeling of compound combinations. When undertaking combinatorial chemistry consider reagents, buffers, resins and standards.Supercritical Fluid ChromatographySupercritical Fluid Chromatography (SFC) is used for the rapid separation and analysis of complex mixtures. SFC systems require injectors, pumps, columns, ovens and detectors. The SFC retention method uses a supercritical fluid, usually CO2. There are a number of different SFC detector types including UV / VIs, ECD, mass spectrometry and fluorescence.NanotechnologyNanotechnology, or nanotech, is an engineering technique using molecular scale functional systems. Applications of nanotechnology include medicine and medical devices, electronics, air and water purification, food science and energy production.Clinical ChemistryBiochemistry (or clinical chemistry) involves the analysis of bodily fluids using chemical tests. Techniques used include HPLC, chromatography, spectroscopy, mass spectrometry, immunochemical, electrophoresis, turbidometric / spectrophotometric assay, MRI and ISE analysis. Tests are often carried out on plasma or serum but urine (urinalysis) and fecal specimens are also processed.Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.
