Total organic carbon (TOC) is an analytical parameter representing the concentration of organic carbon in a sample. TOC determinations are made in a variety of application areas. For example, TOC may be used as a non-specific indicator of water quality, or TOC of source rock may be used as one factor in evaluating a petroleum play. For marine surface sediments average TOC content is 0.5% in the deep ocean, and 2% along the eastern margins.
Soil texture is a classification instrument used both in the field and laboratory to determine soil classes based on their physical texture. Soil texture can be determined using qualitative methods such as texture by feel, and quantitative methods such as the hydrometer method based on Stokes' law. Soil texture has agricultural applications such as determining crop suitability and to predict the response of the soil to environmental and management conditions such as drought or calcium (lime) requirements. Soil texture focuses on the particles that are less than two millimeters in diameter which include sand, silt, and clay. The USDA soil taxonomy and WRB soil classification systems use 12 textural classes whereas the UK-ADAS system uses 11. These classifications are based on the percentages of sand, silt, and clay in the soil.
A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The index of refraction is calculated from the observed refraction angle using Snell's law. For mixtures, the index of refraction then allows to determine the concentration using mixing rules such as the Gladstone–Dale relation and Lorentz–Lorenz equation.
The Liebenauer Stadium, sponsored as the Merkur-Arena, is in the Liebenau area of Graz, Styria, Austria. The ground is the home of the football clubs SK Sturm Graz and Grazer AK.
Small-angle scattering (SAS) is a scattering technique based on deflection of collimated radiation away from the straight trajectory after it interacts with structures that are much larger than the wavelength of the radiation. The deflection is small (0.1-10°) hence the name small-angle. SAS techniques can give information about the size, shape and orientation of structures in a sample.
Static light scattering is a technique in physical chemistry that measures the intensity of the scattered light to obtain the average molecular weight Mw of a macromolecule like a polymer or a protein in solution. Measurement of the scattering intensity at many angles allows calculation of the root mean square radius, also called the radius of gyration Rg. By measuring the scattering intensity for many samples of various concentrations, the second virial coefficient, A2, can be calculated.
Robin Hood Aviation was an Austrian airline, operating from its homebase Graz and from Linz to Zurich. It operated also charter flights. Majority owners were the Austrian entrepreneurs Dr. Helmut Rieder and Dr. Raimund Pammer.
The oscillating U-tube is a technique to determine the density of liquids and gases based on an electronic measurement of the frequency of oscillation, from which the density value is calculated. This measuring principle is based on the Mass-Spring Model.
Particle size analysis, particle size measurement, or simply particle sizing, is the collective name of the technical procedures, or laboratory techniques which determines the size range, and/or the average, or mean size of the particles in a powder or liquid sample.
AHT Cooling Systems is an Austrian company, active in both branches of industrial refrigeration and deep freezing. Its main areas of business are fridges and deep freezers for supermarkets, ice cream freezers and bottle coolers. Daikin acquired AHT in 2019. The company is considered to be a leading producer within the cooling and refrigeration technology market.
Proton-transfer-reaction mass spectrometry (PTR-MS) is an analytical chemistry technique that uses gas phase hydronium reagent ions which are produced in an ion source. PTR-MS is used for online monitoring of volatile organic compounds (VOCs) in ambient air and was developed in 1995 by scientists at the Institut für Ionenphysik at the Leopold-Franzens University in Innsbruck, Austria. A PTR-MS instrument consists of an ion source that is directly connected to a drift tube and an analyzing system. Commercially available PTR-MS instruments have a response time of about 100 ms and reach a detection limit in the single digit pptv or even ppqv region. Established fields of application are environmental research, food and flavor science, biological research, medicine, security, cleanroom monitoring, etc.

Leica Microsystems GmbH is a German microscope manufacturing company. It is a manufacturer of optical microscopes, equipment for the preparation of microscopic specimens and related products. There are ten plants in eight countries with distribution partners in over 100 countries. Leica Microsystems emerged in 1997 out of a 1990 merger between Wild-Leitz, headquartered in Heerbrugg Switzerland, and Cambridge Instruments of Cambridge England. The merger of those two umbrella companies created an alliance of the following 8 individual manufacturers of scientific instruments. American Optical Scientific Products, Carl Reichert Optische Werke AG, R.Jung, Bausch and Lomb Optical Scientific Products Division, Cambridge Instruments, E.Leitz Wetzlar, Kern & Co., and Wild Heerbrugg AG, bringing much-needed modernization and a broader degree of expertise to the newly created entity called Leica Holding B.V. group. In 1997 the name was changed to Leica Microsystems and is a wholly-owned entity of Danaher Corporation since July 2005. Danaher is a US venture capital company.
Otto Kratky was an Austrian physicist. He is best known for his contribution to the small-angle X-ray scattering method, for the Kratky plot, and for the invention of the density metering using the oscillating u-tube principle.
