Gas sampling system



SEMI-GAS Systems, a division of Applied Energy Systems Inc., now offers an automatic gas sampling system that eliminates operator touch time while certifying cylinders of blended gas mixtures. The Samplex, a gas sampling system from the Xturion product line, can sample any gases that can be detected using a Fourier transform infrared (FTIR) analyzer. The system is useful for EPA protocol analysis and for gas suppliers and gas companies that make EPA-approved blended mixtures. It enables more efficient sampling and certification of cylinders, ensuring that certain EPA specifications and requirements, like the EPA Traceability Protocol for Assay and Certification of Compressed Gas Calibration Standards, are being met. Samplex confirms the accuracy of constituent gases within a gas mixture, enables batch analysis, and can display up to six samples. Samplex features a workstation PC with LabView interface and a color touch screen controller. Applied Energy Systems Inc., SEMI-GAS Systems, Malvern, PA, www.semi-gas.com.


Defect inspection system


Nanotronics Imaging has announced new capabilities to its nSPEC semiconductor inspection system. nSPEC now detects and categorizes defects on semiconductor wafers after photolithographic patterning and other chip processing steps. nSPEC has been proven effective for inspection of blank wafers (substrates and epitaxial) across a full range of compound semiconductor materials, e.g., SiC, GaN, GaAs, and InP. The patterned wafer inspection feature gives nSPEC the capability to track wafer quality through the whole chip manufacturing process from bare substrate all the way to fully processed devices. Software has been developed in collaboration with Microsemi Corp. of Aliso Viejo, CA, and supported by funding from the US Air Force. Commercial release of the patterned wafer inspection software for new and existing nSPEC systems is expected in 1Q13; it is currently available for evaluation as a beta version.

Ultrasonic spray system



Spraying Systems Co. has introduced the AccuJet Ultrasonic Spray System, which delivers a precise, extremely fine spray that is good for micron coating, high-precision coating, vaporization, spray drying, and humidification. The Ultrasonic spray nozzle will operate at flow rates that range from 0.5 to 10 cc/min. The high vibration frequency generates fine droplets. Air assist shapes spray pattern and allows adjustment of droplet velocity. Shaping air pressure as low as 0.1psi will affect spray velocity. Spray velocity adjustments can be made to optimize coverage with minimal overspray, resulting in savings on materials and maintenance costs. The spray controller allows for power adjustment to the nozzle and maintains the nozzle at resonant frequency. Applications for ultrasonic spray include: coating of medical devices, (stents, catheters), solar panels and semiconductors; spray drying; humidification (glove boxes); and applications in nanotechnology.
