Introducing the one electron microprobe that really pays for itself. Worldwide, ARL has now installed over 400 scanning electron microprobes. In electronics manufacture, geological exploration, and metallurgical analysis, the SEMQ has proven uniquely cost efficient with outstanding throughput and the provision of the ultimate in useful analytical information. The SEMQ’s ability to handle large samples, up to 4" (10cm) In diameter and 2" (5cm) in depth, and its nine x-ray spectrometers make it extremely flexible and
rapid in either the sequential or simultaneous analysis mode. The x-ray spectrometers feature a 52.5° take-off angle that ensures the highest X-ray efficiency and optimizes the peak to background ratio for elemental analysis. Stateof-the-art back-scattered electron imaging mode provides superb qualitative composition data with resolution of a fraction of an atomic number. Secondary electrons yield high-resolution topographical Information. A complete software system
extends the unit’s total capability. Conversational and interactive in character, SEMQ BASIC software has been designed to allow easy user modification. In short, you can tailor the performance of your probe to make it pay for itself in analyst manhours, research results, and process and quality control.
