LabVIEW virtual instrument

LabVIEW Front Panel display (top) of photomultiplier count rate in counts per second (cps) and block diagram (bottom) for a Virtual Instrument (VI) that measures this. The VI is used to count scattered photons using a counter (ctrO) on a National Instruments M622at PC board and is useful in optimizing die imaging optics and for ensuring adequate count levels for the experiment.

Abstract— In this study, a wireless sensor network (WSN) for flexible pH array sensor has been developed by virtual software of National Instrument (NI) Laboratory Virtual Instrument Engineering Workbench (LabVIEW). The measurement data were received from measurement node and sent to a gateway connecting with computer through WSN. The WSN has been combined successfully with flexible pH array sensor. And the sensitivity and linearity of the flexible pH array sensor received through WSN are 53.39 mV/pH and 0.990 in pH concentrations between pHl and pH13 at room temperate (25 C), respectively. Therefore, the developed WSN can be applied to the flexible pH array sensor practically.

LabVIEW is the abbreviation of Laboratory Virtual Instrument Engineering Workbench, which is the innovative software product of National Instruments (NIs) in United States. It is the preferred platform when people exploit virtual instrument as the most functional graphic software at present [1—5]. 

The virtual instrument system based on LabviewS.O for ion analyzer, which has advantages of easy operation and friendly interface, can determine pX, realize real-time displaying and drawing a curve of pX or mV with the change of time t,... 

A Virtual Instrument (VI), a LabVIEW program whose appearance and operation imitate actual instrumentadon, was written in the present study to acquire and process data. LabVIEW is a program development application, much like various commercial C/C++ or BASIC programing languages. It differs from those other languages in one... 

Chapter 4 presents the recent advances in antibodies research and their applications for immunosensor development. Electrochemical immunosensors for metaUoproteins, nonmetaUoproteins, and cancer cells using their specific antibodies are emphasized. In Chapter 5, the essential components for the development ofbiosensors instrumentation are discussed. Virtual electrochemical instrumentation development using labVIEW is presented. Also, hand held microcontroUer-based electrochemical biosensors are assembled and applied for the measurement of various biomarkers including cytochrome c and nitric oxide metabohtes. These chapters provide the essential background knowledge and up-to-date advances in this field. The book should thus serve as an introductory text for those who intend to specialize in either the theoretical or practical apphcations. It is hoped that this textbook will be a fruitful launch pad for many careers in biosensors and bioelectronics.
