    Laboratory Weighing - Differential Weighing

    Perfecting a classical method. Determining the difference between the initial and residual weights of samples in percent and grams is one of the most frequent routine applications in a laboratory. METTLER TOLEDO offers a complete solution in this area. It consists of a balance, a printer, and application software for the specific balance being used. There is a choice between an integrated balance application, or an optional software cassette which simply plugs into the balance.

    Analysis of Isocyanates Using the ASSET™ EZ4-NCO Dry Sampler

    Isocyanates are used as a raw material to produce a number of products . Personal exposure can occur while the products made with isocyanates are being applied, or when the materials are removed by grinding or thermal degradation. Workers who are exposed to these compounds are at risk for respiratory disorders and asthma. The highly reactive nature of the isocyanate compounds and the low occupational exposure limits put high demands on both sampling and analytical techniques for monitoring of isocyanates in...

    Capabilities of the Adsorbent Tube Injector System (ATIS™)

    The Adsorbent Tube Injector System (ATIS) was developed at Supelco® by R&D Scientists, as a tool to assist in our comprehensive adsorbent research for thermal desorption tubes. The ATIS provides an efficient means of transferring calibration standards in either the gas or liquid phase onto the adsorbent packed tubes. The ATIS employs the technique of flash vaporization to vaporize the sample in a continuous flow of inert gas; the inert gas carries the sample to the tube. The sample pathway of the ATIS is construct...

    Laboratory instruments solutions for environmental industry

    The environmental challenges require internationally accepted standards, in which limits and test methods are defined. Metrohm instruments and applications comply with a lot of international environmental standards. Substances introduced into the environment are distributed among the environmental compartments water, soil (sediment), and air, as well as among the organisms living in them (biosphere). Only if we know the type and quantity of these contaminants can we protect the environment and its inhabitants.

    Validation of Salt Water Disposal Well Treatment Plants with Handheld Oil in Water Sample Analyzer

    Ideally, a continuous online monitor would be used for collecting data to determine upset frequencies, duration and normal conditions. Many of the SWD facilities and demonstration plants do not have a budget that allows for continuous monitoring. However, high frequency sample analysis can be performed on site, using a portable analyzer. Easy to use, low cost field analyzers, such as the TD-500D, are essential for optimizing the effectiveness of treatment systems during pilot studies and meeting a budget that...

    Carbon Dioxide Monitoring for Indoor Air Quality

    Introduction: Accurate control of critical indoor environmental parameters is not only essential for the well-being and comfort of building occupants, but also has a major impact on energy efficiency. A multitude of parameters can affect indoor air quality (IAQ) from gases such as carbon dioxide, carbon monoxide and volatile organic compounds to particulates, humidity and bacteria such as legionella. Carbon dioxide is one of the greatest variables affecting indoor environmental quality since it is produced by...

    Marine monitoring solutions for the SO2/CO2/NOx monitoring

    Process control of a SO2 scrubber on a ship is a challenge due to wet and corrosive gases. In such environment, extractive gas sampling systems require high levels of maintenance in order to operate correctly. OPSIS monitoring system solves this by using an optical, non-contact, cross-duct technique. A light beam is sent across the duct or stack to be measured, and the captured light is sent through an optical fibre cable to an analyser. The analyser measures SO2, CO2 and NOx concentrations using UV and IR...

    Continuous emissions monitoring for CO2 capture

    The process control of a CO2 capture plant needs good and reliable detection of gas phase NH3 and CO2. Measuring NH3 is a challenge due to the corrosive environment and high concentrations of NH3. Several places in the process needs to be monitored and to transport the sample is difficult. A large dynamic range is needed as the NH3 concentration can vary between 15% volume and a few mg/m3.
