From monitoring impurities in vents, stacks, air or water to point source or area monitoring, automatic and on-line measurement is an important tool. This type of measurement will detect, quantify and assist in reducing emissions. Siemens analytical products are utilized for many of these measurements.

Diffuse irradiance measurements: Diffuse Horizontal Irradiance measurements are performed with a thermopile sensor called Pyranometer mounted on a Sun tracker or shading ring. When the pyranometer is installed on an automatic sun tracker, the diffuse radiation can be measured in two different ways. Measuring Diffuse irradiance requires an accurate pyranometer with low offset properties. Duirng clear sky conditions the DHI irradiance (W/m2) is less than 20% of the total irradiance. Zero offsets lead to...
Solar Direct Normal Irradiance (DNI) represents the direct solar component and contains about 80% of the total solar energy budget on earth. Outside the atmosphere (AM0) the solar irradiance is considdered as a constant (1367 W/m2) that slightly fluctuates with a 11 year cycle. The DNI at the earth surface is highly variable due to the atmospheric conditions (clouds, aerosols, water vapor and molecules).
Spectral irradiance is the irradiance of a surface per unit frequency or wavelength. spectral irradiance of a wavelength spectrum is measured per watts per square metre per nanometre (W·m−2·nm−1). Spectroradiometers are devices designed to measure the spectral power distribution of a source. From the spectral power distribution, the radiometric, photometric, and colorimetric quantities of light can be determined in order to measure, characterize, and...Premium
State of the art noise monitoring systems; Modern noise monitoring systems offer a wide range of advanced features and come with software that can analyze and structure long term measurements data efficiently. A complete noise monitoring system consists of one or more noise monitoring terminals, a noise server and work stations for presentation, post processing and reporting.

Reflection and transmission measurements on materials, vegetation, water or atmosphere give valuable information about biological, physical and chemical processes. Processes driven by solar radiation, in particular bands of the spectrum through the so called action spectra, can be analysed or quantified with a sensor senitive in the particular spectral band. The MS-720 portable spectroradiometer gives total freedom to be used in different applications and range of the spectrum between 350 - 1050 nm.Premium
Concentrating Photovoltaics (CPV) is driven by only direct solar radiation. To quantify the energy efficiency of a CPV system the total DNI and direct spectral solar irradiance, called spectral DNI, can be measured. Solar sensors are crucial during the phase of development and operation. Even at high sunny places, the composition and variability of the atmosphere strongly affects the solar spectral distribution and will impact on the energy yield and the decision on which cell type to use. The...Premium
Besides Mass Spectrometry, a further variety of analysis techniques are categorized as atomic spectroscopy. Analysis techniques which use inductively coupled plasma (ICP), such as ICP-OES and ICP-MS, are among these. With increasing environmental awareness backed by regulations, an increasingly important use of atomic spectroscopy techniques is in mercury analysis. Achieving a high mass flow control performance, e.g. high repeatability or an excellent turn-down ratio, is a prerequisite to achieve a high...

Grand Prix racing utilizes cutting-edge high performance engines operation at extreme RPMs and temperatures. To keep the very valuable engines operational and competitive requires a team of mechanics paying careful attention to the engine and lubricant condition. To support this, engine condition monitoring based on oil analysis has become a widely practiced technique by Formula One racing teams.
Not only do the racing teams themselves take Spectro Scientific...
