Sierra Instruments today introduces their new QuadraTherm™ 640i / 780i Thermal Mass Flow Meter Series, marking a disruptive breakthrough in thermal dispersion technology. With its sensor design advancements, coupled with a proprietary iTherm “Brain”, the 780i inline version achieves gas mass flow rate measurement accuracy of +/- 0.5% of reading above 50% of the full scale (Air) making it the most accurate thermal meter in the industry. Before today, this level of accuracy was never thought possible with thermal dispersion mass flow meters.
At the heart of the 640i / 780i is its revolutionary patented QuadraTherm sensor and proprietary iTherm™ algorithm set. Traditional thermal sensors have two sensors–one temperature sensor and one velocity sensor, each in a separate probe. QuadraTherm introduces four sensors—three precision platinum temperature sensors and one patented no-drift DrySense™ mass velocity sensor, which is backed by a lifetime warranty and uses a proprietary manufacturing process to greatly improve accuracy and long-term stability.








FOSS NIRSystems, Inc. (USA) have introduced Vision 3.60. Vision is a software package specifically designed for use with the FOSS NIRSystems Near-Infrared (NIR) laboratory and process analysers. Vision 3.60 replaces earlier versions of Vision and offers support for the latest NIR laboratory and process hardware.
Teledyne Leeman Labs (USA) Hydra IIC Mercury Analyser eliminates the complicated chemistry and hazardous waste associated with conventional mercury techniques. The Hydra IIC is a fully automated turnkey analyser that measures mercury in solid and semi-solid sample matrices directly without any acid digestion (sample preparation).
To efficiently compost waste, continuous temperature readings are required from the compost heap or windrow.
MLE GmbH (Germany) provide a flexible, automated analysis system, developed specifically for water and environmental analysis. It operates with a standard photometric determination method (ISO). The application of flow injection analysis (FIA) allows low reagent consumption, short analysis times and is suitable for large sample throughput (as a multi-channel system, shown in the picture) and also for smaller sample series (single channel system).
An automated segmented flow analyser, the AA3 from SEAL Analytical (UK), is being used at BASF’s manufacturing facility at Ludwigshafen in Germany, to protect manufacturing equipment from corrosion or chemical attack from potential impurities in demineralised water, boiler feed water and steam condensate.
New data from Malvern Instruments (UK) demonstrate how rheological methods can be used to investigate the speed at which biopolymers, such as polylactic acid (PLA), whose low environmental impact is a defining feature, will biodegrade and compost within landfill. The results show how rheological measurements made in the laboratory provide information about the kinetics and thermodynamics of polymer breakdown, helping accelerate the development of products that meet defined biodegradability criteria. The work is presented in a recently recorded webinar entitled ‘Using rheology to assess the biodegradability and compostability of polylactic acid’ and is freely available for download from the Malvern website.
Environmental monitoring specialist, enitial (UK), has been selected as a preferred partner of the National Laboratory Service (NLS) to provide a comprehensive environmental sampling, monitoring and analysis service.
