    Particle Size Measurement

    Particle size is a geometric characteristic that is usually assigned to material objects with sizes ranging from nanometers to millimeters. There is a wide variety of real systems that contain particles within this size range. These systems are generally polydisperse, meaning that the particles in a particular sample vary in size. Therefore, in order to adequately characterize such systems, it is not sufficient to simply determine a single particle size. We must instead determine the system’s particle size...

    Scientific instrumentation solutions for emulsions and microemulsions sector

    Acoustics makes possible measurement of Particle size of the emulsion and microemulsion droplets with no dilution, which is critical for these systems. Papers presented below indicate very good agreement between this method and independent data. Combination of Acoustics and Electroacoustics could reveal peculiar mechanisms controlling emulsion stability, such as ion exchange in water-in-oil emulsion.

    Scientific instrumentation solutions for CMP slurries, content of large particles sector

    There are two papers published on subject of applicability of ultrasound for characterizing CMP slurries, see below. There are also 2 newsletters, # 1 and # 13 on the same subject. Acoustics provides accurate particle size that agrees well with independent data. It can monitor presence of 1% large particles on the background of small nano-particles. Electroacoustics yields very precise value of zeta potential. These measurements can be done with no dilution, which opens possibility for continuous on-line control...

    Particle measurement and sampling equipment for Inhalation aerosol measurements

    Dekati Solutions for inhalation aerosol research include real-time particle net charge and bipolar charge measurement instruments. Dekati BOLAR™ is the only commercially available instrument that can detect both positive and negative charge levels of different sized particles in real-time. This electrical charge carried by inhalation aerosols has been found to have effect on device performance and lung deposition of Dry Power Inhalers (DPI), Metered Dose Inhalers (MDI) and nebulizers. Measuring and optimizing...

    Particle measurement and sampling equipment for Non-Exhaust vehicle emissions

    As exhaust emissions from engine tailpipe have been decreasing in recent years through development of engines and exhaust after-treatment systems, non-exhaust emissions have become a major contributor to total particle emissions from vehicles. Dekati provides complete measurement solutions for brake wear and blow-by gas emission measurements and we can cover the complete particle size using only one measurement method – 6 nm – 10 µm with one measurement method.

  • Personal Exposure During Industrial Process for Glass Breaking

    Various industrial processes create exposure to Ultra fine particles. In case of engineered nanomaterials this is explicit. However, some processes create high exposure rates without EMN being involved. In this study, carried out by ArboNet (Dutch EHS organisation) in cooperation with software partner PIMEX the production of LCD screens with coatings based on nano-size particles was investigated. NanoTracers were used for personal mobile measurement as well as background sensing. Reference sensor was a SMPS. It...

  • 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.

  • Road Sweepers for Hazards on Street

    Several studies made by the Environmental Protection Agency, USA shows that the dirt on the road is just not normal soil but contains hazardous heavy metals. Recent studies have shown that more than 50% of heavy metals and other serious pollutants are attached to particles which measure 60 microns in size and smaller.

  • Gas analysis & monitoring systems 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.
