From specimen collection to delivery of test results, laboratory testing must conform to the highest standards of quality: lives depend on it. Click the image below to read more from APHL.
Use and application of Piezocone Penetration testing in Presumpscot Formation
Abstract: This paper examines the advantages and limitations of CPTu and SCPTu as an exploration method for geotechnical engineering of Presumpscot Formation. Discussion will include typical results of CPTu and SCPTu data for Presumpscot Formation, application and use for settlement prediction, bearing capacity analysis, slope stability evaluation, and seismic design considerations. Intent is to provide an overview of the Use and Application of Piezocone Penetration Testing for the Presumpscot Formation in...

Case study - SP Fire Laboratory, Sweden
Fire laboratory at SP Borås uses EnviBat’s Wet Electrostatic Precipitator technology (WESP) since 2007. Extremely low emissions and high availability are key advantages. Project: WetESP for Fire LaboratoryMany fire tests are made in full scale. Example for fire tests can be engine rooms, vehicles, store houses, compartments etc. Most of the tests will include ignite phase, full fire and extinguishing. The ignite phase is sooting, full fire will give high temperatures (500-700 °C) and the extinguish...
The Five Factors of Smart Laboratory Success
The Five Factors Research organizations are under pressure to cut costs while maintaining or increasing throughput. To improve their operations, many laboratories are considering investments in data management or support and automation systems like ELNs, LIMS or Robotics/HTS. Whatever the change that is introduced, there are many pitfalls on the way to delivery, roll-out and successful adoption. In our experience the key to successful completion of these change programmes is understanding and mitigating the...
Environmental fate and behavior of acesulfame in laboratory experiments
Acesulfame is a widely used artificial sweetener. It can be discharged into surface water by domestic wastewater due to its incomplete retention during wastewater treatment. Concentrations may reach up to 10 μg/L for smaller rivers. State-of-the-art analysis allows the determination of acesulfame traces (0.01 μg/L) and thus a potential tracking of the presence of wastewater in riverbank filtrate. To evaluate the behavior of acesulfame in the aquatic environment, biodegradation and sorption of acesulfame were...
