Thermal Micro-Extraction Laboratory

Typical extractions in the laboratory require a significant amount of sample material, large-scale equipment, and hands-on participation of a scientist. Such a setup is impractical (or impossible), heavy, and expensive to be carried out on spaceflight instrumentation. While great strides are being made to improve spaceflight instrumentation, the front-end sampling and extraction steps are often neglected. Only a few examples discuss the development of extraction systems for spaceflight, and they are immature in development. Additionally, several other microfluidic methods in development at GSFC will eventually require front-end sampling and extraction instrumentation.

Container Screening Device (CSD)

The CSD detects anomalies, contraband, and hidden compartments in liquid-filled containers, and discriminates between threat and non-threat materials.

The Container Screening Device (CSD) is a portable, benchtop measurement system for real-time sealed-container inspection, and content (liquid/ material) classification and discrimination. The technology uses sound waves to acoustically detect, classify, and discriminate threat versus non-threat substances and materials such as liquid explosives, hazardous and flammable liquids, and other caustic or dangerous liquids at security checkpoints. The CSD originally was designed as a prototype for both field measurements and bench-top applications for liquid forensics, intelligence, and law enforcement scenarios.

Product of the Month: July 2017

Tektronix, Beaverton, OR, introduced the TTR500 Series USB vector network analyzer, a USB-based RF test instrument. It includes VectorVu-PC analysis software and built-in bias tee for testing active devices. The 2-port, 2-path S-parameter VNA features 100 kHz to 6 GHz frequency range, 122 dB dynamic range, less than 0.008 dB trace noise, and -50 to +7 dBm output power. The built-in bias tee allows for 0 to ± 24V, and 0 to 200 mA on both ports for active devices. The analyzer operates with any Windows PC or laptop, and VectorVu-PC software controls and calibrates the instrument. For automated test systems in design or manufacturing, the software offers programmatic support for SCPI commands, including command compatibility with common legacy VNAs for integration into existing test systems. In addition, the software offers an offline mode for data analysis with an output file format compatible with common EDA simulation tools. Accessories include a rugged carrying case, rack mount kits, phase-stable cables, attenuators, adapters, and calibration kits.

Flexibility in Low-Cost Microphone Array Systems

As more and more production items are required to comply with a variety of environmental standards, noise control is increasingly key to successful market placement. Effective control of testing costs is equally as critical as deployment of the systems themselves. The ADLINK's fully modular solution provides flexible configuration based on actual demand, while substantially reducing implementation costs, for highly efficient and precise measurement with minimal investment.

National Institute of Standards and Technology (NIST)

The National Institute of Standards and Technology (NIST) was founded in 1901, and is now part of the U.S. Department of Commerce. Based in Gaithersburg, MD, it was established to remove a major challenge to U.S. industrial competitiveness at the time — a second-rate measurement infrastructure that lagged behind the capabilities of the United Kingdom, Germany, and other economic rivals.
