Virtual instrumentation for electro–analytical measurements

This paper deals with some applications of Virtual Instrumentation to electroanalytical measurements. Virtual Instruments (VIs) are software programmes that simulate the external appearance and functions of a real instrument on the screen of a computer. In this work, programmes have been developed to control the potential of a working electrode (through a suitable potentiostat), acquire the cur...

An aid to interfacing analytical instrumentation to laboratory computer systems

Most current laboratory computer systems are based on operating systems designed for multi-terminal access to a shared data-base, and not for real-time data acqusition from on-line analytical instruments. Several years ago this would have caused severe problems, because most instruments produced data output in the form of a varying analogue voltage which needed to be sampled, digitized, and mon...

Use of RFID asset management systems for monitoring analytical instrumentation

radio generation and transmission of radio signals by Ernst F. W. Alexanderson in 1906 signalled the beginning of modern radio communication and, subsequently, radio frequency identification (RFID). RFID is the convergence of radio broadcast technology and radar, although many of its early developments are not widely known due to the military significance of this technology. Most documented his...

The Influence of Space Exploration on Analytical Instrumentation

The lack of organic compounds of biological significance on the Moon has provided carbon chemists with an opportunity to study chemical effects that are a result of solar wind ion implantation into lunar soil grains. The solar wind is the continuously expanding corona of the sun. It impinges on all unshielded objects in space at a velocity of around 400 km s-l. At the distance of the Earth/Moon...
