History

Historically, the definition of a scientific instrument has varied, based on usage, laws, and historical time period.JOURNAL, What Is a Scientific Instrument, When Did It Become One, and Why?, Warner, Deborah Jean, The British Journal for the History of Science, 23, 1, March 1990, 83–93, 4026803, 10.1017/S0007087400044460, 145517920, JOURNAL, United States v. Presbyterian Hospital, The Federal Reporter, 71, 866–868, 1896, Before the mid-nineteenth century such tools were referred to as "natural philosophical" or "philosophical" apparatus and instruments, and older tools from antiquity to the Middle Ages (such as the astrolabe and pendulum clock) defy a more modern definition of "a tool developed to investigate nature qualitatively or quantitatively." Scientific instruments were made by instrument makers living near a center of learning or research, such as a university or research laboratory. Instrument makers designed, constructed, and refined instruments for purposes, but if demand was sufficient, an instrument would go into production as a commercial product.BOOK, Early Scientific Instruments: Europe, 1400-1800, Turner, A.J., Phillip Wilson Publishers, 1987, BOOK,weblink Early American Scientific Instruments and Their Makers, Bedini, S.A., Smithsonian Institution, 1964, 18 January 2017, In a description of the use of the eudiometer by Jan Ingenhousz to show photosynthesis, a biographer observed, "The history of the use and evolution of this instrument helps to show that science is not just a theoretical endeavor but equally an activity grounded on an instrumental basis, which is a cocktail of instruments and techniques wrapped in a social setting within a community of practitioners. The eudiometer has been shown to be one of the elements in this mix that kept a whole community of researchers together, even while they were at odds about the significance and the proper use of the thing."Geerdt Magiels (2009) From Sunlight to Insight. Jan IngenHousz, the discovery of photosynthesis & science in the light of ecology, page 231, VUB Press {{ISBN|978-90-5487-645-8}}By World War II, the demand for improved analyses of wartime products such as medicines, fuels, and weaponized agents pushed instrumentation to new heights.JOURNAL, The Rise of Instruments during World War II, Analytical Chemistry, Mukhopadhyay, R., 80, 15, 5684–5691, 2008, 10.1021/ac801205u, 18671339, Today, changes to instruments used in scientific endeavors — particularly analytical instruments — are occurring rapidly, with interconnections to computers and data management systems becoming increasingly necessary.BOOK, Analytical Instrumentation: A Guide to Laboratory, Portable and Miniaturized Instruments, McMahon, G., John Wiley & Sons, 2007, 1–6, 9780470518557, BOOK, Handbook of Analytical Instruments, Khandpur, R.S., McGraw Hill Education, 2016, 9789339221362,

Scope

Scientific instruments vary greatly in size, shape, purpose, complication and complexity. They include relatively simple laboratory equipment like scales, rulers, chronometers, thermometers, etc. Other simple tools developed in the late 20th century or early 21st century are the Foldscope (an optical microscope), the SCALE(KAS Periodic Table),JOURNAL, KAS PERIODIC TABLE, International Research Journal of Natural and Applied Sciences, Shadab,K.A., 4, 7, 221–261, 2017, the MasSpec Pen (a pen that detects cancer), the glucose meter, etc. However, some scientific instruments can be quite large in size and significant in complexity, like particle colliders or radio-telescope antennas. Conversely, microscale and nanoscale technologies are advancing to the point where instrument sizes are shifting towards the tiny, including nanoscale surgical instruments, biological nanobots, and bioelectronics.BOOK, Systems Engineering for Microscale and Nanoscale Technologies, Osiander, R., Darrin, M.A.G., Barth, J.L., Janet Barth, CRC Press, 137–172, 2016, 9781439837351, BOOK, James, W.S., Lemole Jr, G.M., Technological Advances in Surgery, Trauma and Critical Care, Latifi, R., Rhee, P., Gruessner, R.W.G., Springer, 2015, 221–230, 9781493926718,

The digital era

Instruments are increasingly based upon integration with computers to improve and simplify control; enhance and extend instrumental functions, conditions, and parameter adjustments; and streamline data sampling, collection, resolution, analysis (both during and post-process), and storage and retrieval. Advanced instruments can be connected as a local area network (LAN) directly or via middleware and can be further integrated as part of an information management application such as a laboratory information management system (LIMS).JOURNAL, Integration of instruments and a laboratory information management system at the information level: An inductively coupled plasma spectrometer, Chemometrics and Intelligent Laboratory Systems, Wilkes, R., Megargle, R., 26, 1, 47–54, 1994, 10.1016/0169-7439(94)90018-3, JOURNAL, Integration of Analytical Instruments with Computer Scripting, Journal of Laboratory Automation, Carvalho, M.C., 18, 4, 328–33, 2013, 10.1177/2211068213476288, 23413273, free, Instrument connectivity can be furthered even more using internet of things (IoT) technologies, allowing for example laboratories separated by great distances to connect their instruments to a network that can be monitored from a workstation or mobile device elsewhere.JOURNAL, The Internet of Things comes to the lab, Nature, Perkel, J.M., 542, 7639, 125–126, 2017, 10.1038/542125a, 28150787, 2017Natur.542..125P, free,
