Longer focal length for spectrograph
TOOLS & TECHNIQUES
Diamonds are forever BudgetSensors® now offers a range of diamond-like-carbon (DLC)-coated atomic force microscope (AFM) probes. The hard, nonconductive DLC coating offers high durability and decreased tip wear, thus increasing tip life. The coating has little effect on the tip and all DLC-coated probes have a tip radius <15 nm. A DLC coating is available on the tip side of the cantilever for all silicon probes. An Al reflex coating on the back side of the cantilever is also available for these probes. Contact: www.budgetsensors.com
Longer focal length for spectrograph The Shamrock SR-750 is the latest addition to the Andor range of spectrographs for characterization of materials such as pigments and coatings. It has a 750 mm focal length, f/9.8 aperture, 0.03 nm wavelength resolution, and 68 nm x 68 mm grating. The pre-aligned detector/spectrometer integrates software, electronics, optics, and the detector. Users have full control over all spectrograph functions including wavelength and calibration, grating selection, shutter, slit and filter selection. The gratings can be changed using a triple grating turret located within the unit. Contact: www.andor.com
Working in the ultraviolet Ocean Optics has introduced the Maya2000 and Maya2000 Pro, new two-dimensional fast Fourier transform charge-coupled device (FFTCCD) spectrometers that offer high sensitivity. The instruments offer >90% quantum efficiency, high dynamic range, and good response for low light-level, ultraviolet (UV)-sensitive applications such as fluorescence. A detector collection lens enables enhanced signal collection, and either single or continuous strobes can be used. The 2000 has faster readout times but the 2000 Pro offers a better dynamic range and signal-to-noise ratio. Contact: www.oceanoptics.eu
Spectrometry made easy The Nicolet™ iS™10 with OMNIC™ Specta™ software is an easy to use Fourier Transform infrared (FTIR) spectrometer from Thermo Fisher Scientific. It uses deconvolution protocols to simplify spectrum interpretation and identify individual components in a mixture in one simple step. The Nicolet iS10 can be configured with a Thermo Scientific Nicolet iZ™10 module to allow two accessories, such as attenuated total reflection (ATR) and an integrating sphere or transmission compartment, to be installed at the same time, eliminating accessory exchange time. The spectrometer also features spectral performance verification (SPV), a function that monitors the accuracy and performance of the spectrometer on a regular basis.
Getting to grips with catalysis The Hiden Analytical Catlab for characterization and evaluation of catalytic activity now features a pulse chemisorption (PCS) mode for determination of adsorption isotherms, metal dispersion, and surface acidity. The integrated microreactor and mass spectrometer system enables sample exposure to precisely controlled repeat doses of a reactive gas injected into the primary gas stream, with continuous monitoring of each gas species of interest. Temperature programmed desorption (TPD), reduction (TPR) and oxidation (TPO) experiments can all be carried out on the system. The analysis cycle is fully pre-programmable and automated for linear ramp rate, temperature range, and temperature dwell periods. Contact: www.hidenanalytical.com
Thermo Fisher Scientific has also introduced the analysis package UniQuant® for the ARL QUANT’X, a high-performance energy dispersive X-ray fluorescence (EDXRF) system. ARL QUANT’X is used for rapid qualitative and quantitative, nondestructive elemental analysis of a variety of materials including solids, powders, liquids, and layered structures. UniQuant uses eight filters to collect emission lines and excite every sample. The software can acquire complete spectral profiles and correct all possible overlaps and background effects. The nature of multicondition X-ray excitation and detector resolution made this difficult to perform in previous models.
Plasma works away at the surface Plasma Etch has introduced the PE-100, a new low cost plasma etching system for research laboratories. The PE-100 provides a vacuum chamber that accommodates up to 240” capacity per run cycle.
Sample properties such as area, height, or mass can be specified if needed. An integrated, live sampleimaging camera can identify, isolate, and align very small features and areas, improving the accuracy of standard-less analysis.
The etching system uses a dry radio frequency induced ionized plasma process to uniformly remove organics, coatings, and metal oxides as well as providing a hydrophilic surface. Applications include medical devices, solar cells, optics, printed circuit boards, connectors, and other semiconductor processes.
