Grab frames fast
Ionized-PVD goes retro
For high quality imaging, DataCell’s Phoenix board
SKION’s new retrofit kit converts conventional magnetron sputter cathodes to a negative sputter ion
provides framegrabbing at a transfer rate of up to 528 Mb/s. Particularly suited to fluorescence microscopy, the frame rate and sensitivity can be adjusted for optimum images in specific conditions. Image quality is further enhanced by operating the light sensitive chips at 0°C to reduce noise and allowing

Samples for spectrophotometers A new sample preparation unit/autosampler from Hitachi High-Technologies Corporation is now available for use with the Z-5300 flame only and Z-5000 atomic absorption spectrophotometers. The SSC-400 can accommodate up to 80 15 ml sample tubes and up to eight 50 ml reagent vessels. Reagents can be added to the sample in volumes from 0.1-5 ml. Standards can be measured automatically and calibration curves produced. Samples can be diluted by a factor of 2-100 times and measured. The SSC-400 can also be used with the spectrophotometer’s automatic QC facility to test validity of calibration data and other parameters, ensuring reliability and accuracy of the analysis data.

MKS Instruments Inc. announces a portable, selfcontained mass spectrometer-based leak detector
Designing materials Supramolecular Organization and Materials Design edited by William Jones and Chintamani Rao demonstrates the importance of supramolecular chemistry and self-organization in the design and synthesis of novel organic, inorganic, and biomaterials. The bottom-up approach of supramolecular chemistry is looked at in the context of the synthesis of new materials and function-specific molecular devices. Published by Cambridge University Press (CUP), this book will be of interest to researchers and graduate students of chemistry, materials science, and physics who require a summary of the most recent developments in this field.
