This internship summary outlines Isaac Hardison's work at an environmental engineering internship. Some of his projects included updating process flow diagrams, stack testing, and evaluating monitoring equipment for pH, phosphates, and total suspended solids. He found that adding defluorinated phosphate increased water pH. Phosphate and TSS monitors showed good accuracy compared to lab analyses. Through this internship, Isaac learned about experimental design, water quality monitoring, and working with other departments. He thanks the various teams and departments that supported his learning experience.

Analysis of Volatile Organic Compounds (VOCs) in Air Using U.S. EPA Method TO-17PerkinElmer, Inc.
EPA Method TO-17 is used to determine toxic compounds in air after they have been collected onto sorbent tubes. These tubes can either adsorb specific compounds or adsorb a broad range of compounds, quantitatively. Adsorbent tubes have many applications in the investigation of volatile organic compounds (VOCs) found in EPA Method TO-17. Examples include indoor air, fence line, stack, workplace, personal monitoring and soil gas. The type of tube used, and whether the sampling is passive or active, depends upon the need at the particular site being investigated. This application note demonstrates that the PerkinElmer TurboMatrix™ Thermal Desorber and the PerkinElmer Clarus® SQ 8 GC/MS will meet and exceed the criteria set forth in EPA method TO-17. Detailed instrument method parameters are presented, with precision, recovery, linearity and detection limit results.
Investigation into the design and application of solid core stationary phases has led to a better understanding of how the phases work and has resulted in their design aligned to the structure of the analytes being separated. The current range of columns available is discussed both in terms of selectivities, and also morphologies, allowing informed decisions to be made by the chromatographer. Using real life examples, coupled with advanced modeling, the effects of the particle size and morphology will be given for both small and large molecules, offering an insight into what the future holds for solid core products.
In the pharmaceutical arena there is great interest in solid core technology, where there is a broad range of sample types as well as requirements throughout the process of developing new chemical entities. The presentation looks at how solid core technology can be readily adapted to cope with the challenges associated with the pharmaceutical sector, looking at various sample matrices and molecular entities, from small molecules to large biomolecules. The presentation gives an insight into how varying the solid core to porous layer allows the user to optimize separation performance by reducing extra band broadening. Data presented demonstrates how this technology is more robust than fully porous systems when analyzing biological extracts, routinely used in DMPK departments, resulting in longer column lifetimes.
Life Cycle Management of Chromatographic Methods for BiopharmaceuticalsWaters Corporation
The development and manufacture of biopharmaceuticals is a dynamic and rapidly growing industry. By the nature of their production, biopharmaceuticals are highly complex heterogeneous mixtures that require many analytical techniques for characterization and routine testing. As a result, many manufacturers incorporate life cycle management into their respective workflows to take advantage of newer technologies and methodologies to ensure efficacy and patient safety.
In this presentation, we will address the range of chromatographic categories – HPLC, UHPLC, and UPLC – and define the characteristics associated with each. The discussion will continue with several examples of methods transferred from legacy HPLC instrumentation to modern UHPLC and UPLC instruments. We will compare qualitative and quantitative data across each chromatographic class. Resolution, sensitivity, and overall run time will be used as metrics to assess the success of the method transfer to the respective LC platform, to ensure the transferred methods are in line with current acceptance criteria.
Learn:
- The importance of selecting the correct instrumentation to meet user needs.
- Which parameters influence method transfer from one LC platform to another.
- How workflows can benefit from features such as Multi-flow path technology and Gradient SmartStart when transitioning methods.

Why are proficiency testing programs useful?ExternalEvents
First lab managers’ meeting of the South-East Asia Laboratory NETwork (SEALNET 2.0) - Quality improvement in Asian soil laboratories: towards standardization and harmonization of soil analyses and their interpretation, Bogor, Indonesia, 20 - 24 November 2017.
Today’s analytical laboratory is faced with tight deadlines to produce results from testing environmental samples. Too often, solid-phase extraction (SPE) presents a bottleneck in the analytical testing process and may cause poor analyte recoveries and highly variable. Despite advances in analytical instrumentation, sample prep often relies on tedious, manual, and expensive techniques such as liquid-liquid extraction.
Sample preparation of environmental water samples can be automated, however.. Use of automated sample preparation addresses the many challenges that laboratories face when preparing samples and can help improve sample processing turnaround times.

Chris Impellitteri: EPA's update on PFAS analytical methodsOECD Environment
On 11 June 2020, the OECD hosted a webinar on the latest developments in analytical and monitoring methods for PFASs. It is important to understand the levels and trends of PFASs in the global environment, biota and in products so as to take relevant measures to reduce environmental and human exposure.
The webinar featured the following speakers:
Introduction by Eeva Leinala, Principal Administrator, Environment Directorate, OECD
Shoji Nakayama, Centre for Health and Environmental Risk Research, National Institute for Environmental Studies, Japan presented work on worldwide trends in tracing PFAS in the environment;
Chris Impellitteri, EPA’s Office of Research and Development, United States presented an update on EPA’s Analytical Methods for PFAS;
Stefan Posner, Independent researcher, presented work on the development of CEN and ISO test methods for the analysis of PFAS in textile and leather.

Application of Aqsens Technology: Case studies presented at SPE Oilfield Chem...Aqsens Oy
Aqsens novel method for testing polymeric scale inhibitor was presented with two case studies at SPE International Symposium on Oilfield Chemistry 13th-15th April 2015 in Texas.
Polymeric scale inhibitors can be difficult to detect at MED levels even with sophisticated analytical procedures. The necessary equipment is located in remote laboratories causing delays in obtaining results. It can take weeks to know the effectiveness of the scale control program.
Novel Aqsens technology is based on time-resolved-fluorescence method. It opens the possibility to control scale program efficiency infield with portable field lab unit. The results are ready for use in 10-15 minutes depending on the concentration.
The case studies presented at SPE symposium tested how well Aqsens technology performs compared to current testing possibilities such as HPLC. Aqsens effectiveness was demonstrated on more than 90 produced water samples collected from offshore and onshore wells.
See the full case studies on onshore mature heavy oil field and North Sea fields from attached SPE presentation.
