Educating the Next Generation of Metals Chemists

UW Bothell School of STEMDr. Hakan Gürleyük, Brooks Applied Labs’ Technical Director and Sr. Scientist, was recently a Chemistry Seminar Series guest lecturer at the University of Washington – Bothell’s School of STEM. On March 13th Hakan led a class of approximately 45 undergraduate chemistry students as they learned about “Speciation Analysis Using ICP-MS”. Visit our website if you would also like to learn more about trace metals speciation, or to receive a copy of the slide deck from this presentation, please contact us.

BAL is On the Road Again…

EWCPS - Pau, France 2019BAL’s methods are predominantly based on ICP-MS technology so it should surprise no one that the Winter Conference on Plasma Spectrochemistry is one of the highlights of our year. This year’s conference takes place February 3-8 in Pau, France, and Dr. Nausheen Sadiq will be presenting exciting new research on iodine isotopic ratio analysis in kelp samples. BAL’s Dr. Hakan Gürleyük and CEO Michelle Briscoe will also be attending this year’s conference. Please contact us if you will be attending and you’d like to connect, or if you would like more information about this new method!

Battelle’s Conference on Remediation and Management of Contaminated Sediments will be held February 11-14 in New Orleans and BAL’s  Dr. Stephen Springer and Jamie Fox will be attending. Stephen will be presenting a poster on an exciting new method that he developed for the determination of elemental mercury in soils. Please contact us if you will be attending or if you would like more information about this new method!

ACCBIOBAL’s Business Development Director, Russ Gerads, will be attending the International Conference on Accelerating Biopharmaceutical Development in Carlsbad, CA from February 17-20. Schedule a meeting with Russ to learn more about our novel technologies for not just advancing biopharmaceutical development but achieving greater yield and reducing risk in your current operations through chemistry.

Quantifying Trace Selenium in Seawater

The Coast at SunsetBrooks Applied Labs (BAL) is now offering the most innovative method commercially available for the quantitation of selenium in saline waters at concentrations as low as 5 ng/L (parts-per-trillion). BAL’s novel method utilizes in-line matrix component separation and preconcentration, is fully automated, and has no spectral interferences attributed to the saline matrix. Ultra-trace detection limits for selenium in saline waters (such as seawater, brackish waters, RO reject water, and brines) to support discharge requirements and investigations for estuaries, bays, near shore and open ocean, and saline lakes with unparalleled quality are now a reality.

Inductively coupled plasma mass spectrometry (ICP-MS) is a powerful and efficient tool for the determination of low-level metals; however, the high salt content of seawater can lead to elevated method detection limits and inaccurate results. Several methods have been developed that utilize reaction-based chemistry (e.g., hydride generation and coprecipitation) to remove selenium from the saline matrix prior to analysis. Trace-level detection limits have been achieved with these methods; however, reaction-based chemistry has inherent limitations and is susceptible to interferences from elevated concentrations of common constituents found in seawater and procedural inefficiencies.

The need to improve method robustness, reduce operational costs, and increase data quality motivated BAL scientists to generate this new method to meet both our client’s needs and the needs of regulatory agencies around the world. As part of our commitment to quality, BAL’s new method has undergone extensive validation confirming both inorganic and organic molecular forms of selenium are represented in our results, making it a truly species-independent quantitative approach.

Monitoring elements at environmentally-relevant concentrations in seawater is critical for developing accurate environmental assessments and evaluating the effectiveness of various pollution controls. BAL’s improved methodology allows for an unprecedented level of data quality at concentrations as low as just a few parts-per-trillion.

Mark Your Calendars: BAL Giving ACS Webinar

On May 3rd, our Technical Director, Hakan Gürleyük, will be presenting a webinar sponsored by Agilent through ACS’s Chemical & Engineering News (C&EN). The title is “Why ICP-MS/MS? How Tandem MS Solves Analytical Problems and Improves Data Quality in a Commercial Metals Laboratory.” Please join Hakan for what will be a highly informative and important discussion on the future of metals analysis by registering here.

In Case You Missed It: BAL Presentations February – April

If you follow our newsletters, you probably have noticed that BAL staff have had a busy winter and spring attending and presenting at many conferences around the country and even overseas. In case you missed any of the announcements or would like a copy of the presentations, here is a recap:

In February, Jamie Fox, presented at the Energy, Utility & Environment Conference in San Diego on Wastewater Selenium Chemistry in Bioreactor Treatment Systems (contact Jamie for a copy of the presentation). Also in February, two of our scientists, Dr. Hakan Gürleyük and Tamas Ugrai, presented at the European Winter Conference on Plasma Spectrochemistry in Austria. Hakan spoke about the Determination of radium in natural waters using IC-ICP-MS after on-line preconcentration (contact us for a copy of the presentation), while Tamas presented on Reducing the risk of inaccurate results when quantifying trace elements in seawater using ICP-QQQ-MS.

In March, Elizabeth Madonick, presented a poster at the AEHS Foundation’s International Conference on Soil, Water, Energy, and Air in San Diego on Reducing the Risk of Inaccurate Results When Quantifying Trace Elements in Seawater.

And then last month, Jamie presented at the Department of Defense Environmental Monitoring and Data Quality Workshop in Phoenix on Advances in Detection of Hexavalent Chromium, while Michelle Briscoe presented the same week at the ACIL Policies and Practices Meeting in Washington, D.C. on Reducing the Risk of Staff Turnover: Developing Great Managers and Culture.

Stay tuned for future conference announcements and presentations through our newsletter. Hope to see you out on the road!
