Cell sorting plays a fundamental role in molecular biology, pathology, immunology and virology research. It requires the ability to rapidly search through and sort out cells based on their unique chemical features and shapes. Conventional methods are limited in uncovering these differences, or are too labor or time intensive, or have to tradeoff between speed and accuracy. The Department of Chemistry at the University of Tokyo has developed an intelligent Image-Activated Cell Sorter (IACS) with an ultra-fast Spectrum Instrumentation digitizer at the heart.

The VivoSight® OCT scanner uses the technique of swept-source Optical Coherence Tomography (SS-OCT) for cross-sectional imaging of skin. This is a significant new tool to assist in diagnosis and treatment of skin cancers and other skin conditions.

Over 140 digitizer cards from Spectrum Instrumentation are being used in the machine protection systems of the Large Hadron Collider (LHC) at CERN. The cards are used to check that the particle beams have been accurately deflected. Incredible precision is required for this as two high-energy particle beams travel at close to the speed of light in opposite directions in the 27 km LHC accelerator ring. They are then made to collide at four locations around the ring for runs of several hours. The particles are so tiny that the task of making them collide is akin to firing two needles 10 kilometers apart with such precision that they meet halfway.

CPU based embedded systems now play an increasing part in the monitoring and control of the mechanical and electrical components in many areas of our technological environment.

The scientific field of Mass Spectrometry (MS) has been under constant research and development for over a hundred years, ever since scientists discovered that charged particles could be separated via electromagnetic fields based on their charge-to-mass ratio (Q/m). While spectrometry systems now come in numerous configurations their performance largely depends on a few fundamental elements. In the modern Mass Spectrometer this is normally the ion source (for exciting ions from the material under analysis), the mass analyzer, the particle detector and its associated electronics.

Atmospheric research uses pulsed laser beams to measure temperature and wind speed along the beams by measuring the Doppler shifted and backscattered light at 100 km height in the atmosphere. The returning light signals are very weak and can be blocked by sunlight, but The Leibniz Institute for Atmospheric Physics (IAP) has solved this problem: they developed the world’s only portable instrument that can be used during the daytime and it has already provided new insights into Antarctic atmospheric conditions. This new generation of compact and reliable systems uses a novel, diode-pumped laser and, at its heart, are a Spectrum Instrumentation Arbitrary Waveform Generator (AWG) and two Digitizers that provide the extremely high speed, sensitivity and real-time capability required.
