Position: Precision to the Very Last Particle
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.
For an accurate differentiation of the smallest weights we offer a complete portfolio of filter weighing kits. They fit perfectly on microbalances, ultra microbalances and analytical balances. To complete the solution we offer a printer or if preferred, LabX balance PC software for customized data handling.
We also offer the world’s first automated weighing solution for the measurement of particulate matter in the automotive industry. This innovative filter robot solution, especially designed for diesel engine emissions, enables easy, fast and cost saving weight determination of particulate matter.
Determining the weight of particulate matter is a key task in emission testing and one which is likely to become even more important as emissions standards become stricter.
The robotic filter weighing solution and the Excellence Balances equipped with a Filter Weighing Kit provide a state-of-the-art solution for emissions determination. The Mettler Toledo measurement and weighing system enables fast and accurate weight determination down to 0.1 μg, meeting strict automotive and environmental requirements.
Microsep offers a complete solution to monitor environmental pollutants using Millipore membrane filters, cassettes and aerosol analysis monitors, available with 0,45 μm and 0,8 μm cellulose ester membranes. Matched weight monitors can contain two filters matched in weight to within 0,1?mg, eliminating test filter pre-weighing in gravimetric analysis applications.
Subsequent filter weighing is simplified using a Mettler Toledo high precision microbalance or analytical balance. An appropriate filter set can be included, depending on the size of the filter and the required measuring accuracy.
Weighing filters with Mettler Toledo MX or UMX micro- and ultra-microbalances, with resolution of up to 0,0001 mg, require special care in order to avoid electrostatic charges or other physical effects that could lead to improper results. This specific range of balances and accessories are specially designed for such delicate measurements using the most advanced weighing technology available, together with metal shielded filter sets. Two different sets are available - for filters up to 50 mm in diameter or 110 mm in diameter, with 0,002-0,1 mg resolution.
For large and/or heavier filters, filter weighing can be done with a Mettler Toledo AX analytical balance and an appropriate filter set. An optional RS42 printer can be attached to the balance in question for easy and error-free documentation including date, time and/or sample ID.
