Varian, Inc has extended its line of cold probes for NMR with the 13C Enhanced HCN (hydrogen, carbon, nitrogen) Cold Probe that enables the use of a single probe, rather than several different ones, to run a wide variety of applications. A probe is a critical device that holds the sample within the magnet bore and makes possible both the transmission and detection of RF signals. A cold probe is cooled to reduce the resistance of its multiple detector coils to zero, and thus reduces noise. The 13C Enhanced HCN Cold Probe features an increased carbon sensitivity that allows four times greater speed or much smaller sample size—by half—in conducting carbon-observe NMR experiments. Such experiments are common in the pharmaceutical and life science sectors where users often must run both hydrogen (proton) and carbon NMR spectra.

Newport Corp has introduced the OSM-400, a portable spectrometer with a choice of spectral ranges to cover the UV through the near-IR. The UV model offers the 250–550 nm range; the UV/visible model, 250–850 nm; and the VIS-NIR model, 500–1000 nm. Optical input is via a fiberoptic/SMA connector or directly through the input slit. With an onboard 32-bit processor, color liquid crystal display, and graphical user interface for data display and touchscreen control, the OSM-400 can carry out local data analysis in real time. Data can be stored, archived, and transported on removable SmartMedia memory cards or downloaded through an RS-232 link or optional 10/100 Ethernet port. The new spectrometer provides resolution up to 0.5 nm and uses a 12-bit A/D converter with a high dynamic range for data acquisition. Newport Corp, 1791 Deere Avenue, Irvine, CA 92606,

The CEDIP Infrared Systems Altair Li Workstation produces high-quality images of stress in materials and structures under dynamic loading conditions. Altair Li uses the company’s JADE IR focal plane array camera to provide thermal images of the scene at fast frame rate. When a structure undergoes cyclic loading, small temperature changes are produced at its surface. Under adiabatic conditions, a linear relationship exists between temperature variation and localized stress; the Altair Li makes use of this thermoelastic effect. The transformation of the thermal images into stress images is made by software, without any contact with the material surface. In its D-mode, the system can measure heat dissipation in a structure under dynamic loading. CEDIP Infrared Systems, 19 bd Bidault, F-77183, Croissy Beaubourg, France,

Ocean Optics has developed the Foxy-Lite handheld oxygen sensor, which uses time-resolved fluorometry and sol-gel based optical sensing technology to calculate oxygen concentration in a sample. The Foxy-Lite includes the company’s Foxy-R, a 1-mm stainless steel probe whose transducer material consists of a fluorescent ruthenium complex immobilized in a submicrometer-thin sol-gel matrix. The instrument’s onboard blue (470 nm), pulsed, LED light source excites an analyte, while its filtered single-element detector, determines oxygen levels by capturing the sample’s fluorescence decay at 600 nm; the response time is less than 1 s. Oxygen levels may be displayed in ppm or in percentage values. The sampling probe couples to the Foxy-Lite through a 600-µm bifurcated optical fiber.

Axios from PANalytical (formerly Philips Analytical) is a new range of wavelength-dispersive x-ray fluorescence spectrometers. The instruments feature a new x-ray tube, the SST-mAX, which offers stable tube output up to 160 mA and thus improves performance in the light element range. Axios also incorporates the latest innovations in multilayer technology for analyzing crystals; through these innovations, sensitivity can be doubled for elements such as boron. The new spectrometers can handle up to 168 samples at a time and measure and analyze samples including solid pieces, pressed and loose powders, fused beads, liquids, and thin films. All Axios systems run on a new version (4.0) of the company’s SuperQ software, a modular design with multiple program options for specific industries and analysis needs.

OPTRA, Inc has introduced the OP-FTIR open-path Fourier transform IR spectrometer for quantifying volatile organic compounds in industrial settings. The system includes an encoder-based reference system, operation in the “fingerprint” region of the IR spectrum (7–14 µm) at a spectral resolution of 8 cm−1, an uncooled pyroelectric detector, and a plastic injection-molded retro-reflector array. The OP-FTIR operates over an extended path; the optical probe beam is double-passed through the defined path volume using a retro-reflector at the distal end to return the beam to the transceiver. The spectrometer uses automated software algorithms that incorporate artificial neural networks and partial least squares to discriminate and quantify a list of 105 organic compounds in the presence of varying humidity levels.

The McPherson FL-750 Fluorescence Detector with an included laptop computer delivers digital control of sensitivity, wavelength, and signal acquisition. It can be configured for dynamic flow and high-pressure liquid chromatography applications (FL-750B and BX versions) or used with cuvettes for static analysis (FL-750A). The much higher sensitivity of fluorescence detection usually determines when fluorescence is used in conjunction with or instead of absorbance. Application-optimized light sources guarantee enhanced excitation, so three different CW sources are available: deuterium, xenon, and xenon-mercury. The FL-750 fluorescence detector efficiently collects emission spectra. The user can choose between two detection modes: a monochromator for highest selectivity, or a filter for highest sensitivity.

The Orion upgrade from JEOL improves the performance of its analog- and DOS-based scanning electron microscopes. This is done with new computer hardware and software that allow rapid digital-image acquisition and control, frame averaging, and frame integration. The upgrade consists of a Microsoft Windows XP-equipped PC configured with software that acquires highspeed-averaged and slow-scan images for storage and recall. Orion allows the user to manage and create recipes, view live and stored images, and control specified functions. For later model SEMs, the addition of an electron optics control package permits access to most column control through the desktop or a knobset. A third version of Orion enables the driving of stage coordinates by joy-stick, numerical entry, incremental step, or location recall. JEOL USA Inc, 11 Dearborn Road, Peabody, MA 01960,

The 428 EC Cell Blackbody Source from Isotech North America was developed by the National Physical Laboratory in the UK for the calibration of IR tympanic thermometers (ITTs). The cell creates a fixed temperature of 36.3°C (97.3°F) while its ethylene carbonate contents melt or freeze; the repeatability is better than ±0.02°C. The blackbody cavity consists of a cylindrical cone approximately 40 mm in diameter, suitable for the wide-angle field-of-view characteristics found in some ITTs. The new portable fixed-point cell was developed to provide clinicians with a means of validation for ITTs in the environments in which they are used, such as wards, clinics, and general practices. The company also offers the EC Cell Melter. Isotech North America, P.O. Box 636, 10 Leroy Road, Williston, VT 05495,
