    AutoChem - Formulations and Product Development

    The particle size distribution is one of the most critical parameters in drug product quality. Real time understanding and control of particles ensures Quality by Design (QbD) in solid and liquid dosage formulation. FBRM and PVM Process Analytical Technologies (PAT) provide in-process real time measurements of particle dimension, particle shape, and particle count. FBRM and PVM are used to promote faster formulation development, improve process confidence, and control batch-to-batch consistency.

    Laboratory Weighing - Filter Weighing

    Traffic means mobility and air emissions. Thanks to economical advantages, diesel engine becomes more and more popular, but particle emission is strictly restricted by regulations. Determining the weight of particulate matter (PM) is a key task in the automotive industry and one which is likely to become even more important as emissions standards become stricter. To allow fast and easy measurement of particulate matter at any time, METTLER TOLEDO has developed new filter weighing solutions.

    PTR-TOFMS systems for automotive real-time vehicle exhaust analysis

    Monitoring exhaust gas from combustion engines, emitting a large number of different compounds and with rapidly changing concentrations due to variations in operating conditions, necessitates an instrument that measures in real-time and with high sensitivity – an IONICON PTR-TOFMS.

    Particulate matter, halogens and aerosols

    Without CTP's innovative upstream systems, regenerative thermal oxidation would not be possible, which would render the waste gas purification cost-intensive and inefficient. Continuous burning off in the RTOs eliminates the deposits which periodically clog the ceramic honeycomb blocks.

    Gas monitoring instruments and systems for titanium dioxide

    Titanium dioxide is the most important white pigment used in the polymer industry. It is widely used, because it efficiently scatters visible light, thereby imparting whiteness, brightness, and opacity when incorporated into a plastic product.

    Low level measurement of VOCs and Terpenes close to the sea and the Landes Forest

    It has been established that organic aerosol (OA) makes up for a major fraction of fine particulate matter in all region of the atmosphere. This fraction accounts approximately for half of the total PM2.5 dry mass.1,2 Primary OA is directly emitted in the troposphere from anthropological and natural sources whereas secondary OA (SOA) is formed in-situ in the atmosphere from the oxidation of biogenic or anthropogenic gas-phase precursors and subsequent partitioning of the less volatile products into the particle phase. The current number is that, on a global scale, SOA would represent around 60% of the overall OA.3 However, recent global mass-balance estimations for the removal of volatile organic compounds (VOC) suggest that this number could under-predicts SOA production.4 Recent field measurements in urban locations are also in support of a larger share, indicating that SOA is the dominant fraction of OA, with amounts considerably 20 greater than models predictions.

    Gas monitoring instruments and systems for engine emissions measurements

    The exhaust gas from combustion engines is a complex mixture of gases and particulate matter. The composition of the gas may change rapidly. Multicomponent analysis of exhaust gases can be performed with a Gasmet™ FTIR Gas Analyzer with a response time (T90) of one second. The winning combination is the result using of a small volume gas sample cell, a powerful sample pump and a fast detector with liquid nitrogen cooling. The analyzer, sampling system and computer can be assembled on a cart for use in a dynamometer laboratory, or the portable version can be used for roadside tests.

    Air quality monitoring

    To estimate the effects of aerosols on health and climate, it is essential to know their chemical composition. Sampling is done using two different types of aerosol collector. The first type are filter collectors that are based on the deposition of suspended particles on surfaces; the second type are powerful aerosol collectors.

    Air Pollution Control Solution for the FGD - SO2

    Flue Gas Desulfurization (FGD) involves the removal of sulfur dioxide and other acids from flue gases. Typical sources of acid gases include fossil fuel boilers, waste combustors, and other industrial applications such as refining and smelting. The Macrotek wet and dry FGD systems can achieve over 99% acid removal by using a variety of reagents, including caustic, sodium carbonate, lime and limestone, and waste alkaline solids or liquids.

    High quality gas sensor solutions for building and IAQ

    Precise measurement of air quality. The carbon dioxide content of room air gives a measure of the air quality, especially as it relates to the health and comfort of the people occupying the building. Air quality can be adversely affected by increased levels of carbon dioxide, carbon monoxide, volatile organic compounds (VOCs), particulates, or bacteria. Increased ventilation reduces the level of all of these unwanted contaminants. Measuring the CO2 concentration provides an economical way of ensuring that there is sufficient air circulation and prevents over-ventilation which can add unnecessary heating or cooling costs.

    Gas analysis & monitoring system for dust

    Particulate matter, suspended particulate matter, atmospheric dust, particulate matter, total suspended particulate (TSP), are terms that commonly identify the group of substances suspended in the air (fibers, carbon particles, metals, silica, polluting liquid or solid). Particulate matter is the pollutant that is now considered the greatest impact in urban areas, and is composed of all those solid and liquid particles dispersed in the atmosphere, with a diameter ranging from a few nanometers to 500 microns and above (ie billionths of a meter to half a millimeter).

    Gas analysis & monitoring system for emission monitoring

    From the environmental point of view, an issue is any solid, liquid or gaseous substance introduced into the atmosphere that can cause air pollution. Given the wide variety of substances present in the atmosphere, have been proposed several methods of classification: Primary pollutants can be of gaseous or particulate.

    Industrial Solution for metallurgical, mining & chemical

    Hydrometallurgical extraction of metals such as Nickel and Cobalt generate emissions of lethal gases such as Hydrogen Sulphide or Hydrogen Chloride. Macrotek has designed and supplied many systems to capture and treat these gases. In most cases the by-product is returned back to the process for reuse. Pyrometallurgical extraction of metals from sulphur containing ores generate large amounts of SO2 and particulate emissions. Macrotek has designed integrated systems to capture particulate and neutralizes SO2.
