Leak Detector Guidance for FreonTM Refrigerants

Refrigeration service personnel have used leak detection equipment for years when servicing refrigeration equipment. In the past, leak detection typically was only concerned with leak pinpointing, either with an ultrasonic device, soap bubbles, dyes, thermal conductivity, or other electronic devices. Today, refrigerant leak detectors exist not only for pinpointing leaks, but also for monitoring...

Electric Ion Dispersion as a New Type of Mass Spectrometer

At the 2014 Fields-MPrime Industrial Problem Solving Workshop, PerkinElmer presented a design problem for mass spectrometry. Traditionally mass spectrometry is done via three methods: using magnetic fields to deflect charged particles whereby different masses bend differently; using a time-of-flight procedure where particles of different mass arrive at different times at a target; and using an ...

Development of a Miniature Mass Spectrometer and an Automated Detector for Sampling Explosive Materials

The development of a robust ionization source using the counter-flow APCI, miniature mass spectrometer, and an automated sampling system for detecting explosives are described. These development efforts using mass spectrometry were made in order to improve the efficiencies of on-site detection in areas such as security, environmental, and industrial applications. A development team, including t...
