A team of Eurofins scientific experts will head to San Diego Aug 25 through Aug. 29 as part of the American Chemical Society’s Fall 2019 National Meeting & Exposition

One of the largest scientific conferences of the year, ACS’ National Meeting features more than 9,500 presentations on the meeting’s theme, “Chemistry & Water,” and topics such as food, nutrition, medicine, health, nanotechnology, space science, energy and the environment.

During the conference, seven Eurofins scientists will be presenting on range of topics ranging from early career guidance at a Contract Research Organization to how best to overcome challenges when running SANCO-compliant method validations in support of ecotoxicological studies. In addition to the presentations below, Eurofins will also be hosting a table at the ACS Division of Agrochemicals’ VIP Meet and Greet on Aug. 27.

Chromatographic Separations of Several Functional Analogs
Presented by Tanuj Chowdhury
1:05 p.m., August 25 in Ballroom 20B-D, Theater 3 | Click to add to calendar
Chromatographic separations of several functional analogs which contain either α, β unsaturated ketone, ketone, alcohol or carboxylic acid functional groups, which do not have strong UV absorbance are a challenge to detect. In this presentation you will learn how Eurofins scientists evaluated several methods using SPE and/or TLC to separate the mixture of compounds and how TLC separation followed by visualization of compounds using various staining reagents was useful to detect non-UV absorbing compounds.

Lessons Learned From Starting Career at a Contract Research Organization
Presented by Sara Whiting
1:05 p.m., August 26 in Ballroom 20B-D, Theater 2 | Click to add to Calendar
Learn about one Eurofins scientist’s experience starting her career as part of a global CRO. This presentation will explore the excitement of getting your first real job after graduate school, as well as some of the highlights of working for a CRO, including the fast-paced environment where scientists switch between analytes or chemistries on a daily basis, if not more frequent, as well as the stability of an industry-related position over something shorter-term, like a post-doctoral position in an academic laboratory.

Method Development and Optimization for Extracting a Pesticide From Bee and Corn Pollen
Presented by Sara Whiting and Kevin Clark of Eurofins Agroscience Services
9:25 a.m., August 28 in Ballroom 20B-D, Theater 3 | Click to add to Calendar
Learn how Eurofins scientists approached a project in which they were provided a complex analytical method to extract a pesticide from pollen. After some trial and error, they simplified the extraction method and modified the instrument parameters to fully validate a method.  This presentation will highlight some of the trial and error procedures and how they were able to successfully validate the method.   

Challenges, Approaches and Achievements on Surface Water Mineralization with Amended Solids: Case Study for Insoluble Compounds and High Volatility
Presented by Robin Lomax
8:35 a.m., August 28 in Ballroom 20B-D, Theater 4 | Click to add to Calendar
Mineralization studies (OECD 309) main objective is to determine the biodegradation rate of a test substance in aerobic natural water as well as degradation and formation of transformation products other than CO2. In this presentation, you will learn how Eurofins scientists were able to address the challenges of conducting mineralization studies on compounds with extremely low solubility in aerobic natural water with amended sediment and our approaches to achieve recoveries from various types of materials, while dealing with challenges of highly volatile compounds.

The Obstacle Course of Running SANCO Compliant Method Validations to Support Ecotoxicology Studies
Presented by Ling Zhang and Kathy H. Martin
4:30 p.m., August 28 in Ballroom 20B-D, Theater 3 | Click to add to Calendar
In recent years, the regulatory authorities have scrutinized more strictly the analytical phase of ecotoxicology studies to ensure that a reliable analytical methodology is used to conduct risk assessment.  This emphasis by authorities on analytical methods poses new challenges to analytical laboratories that conduct method validations to support exposure concentration verifications in ecotoxicology tests. In this presentation you will learn some of these challenges that Eurofins encountered in recent years and our effort to meet all the regulatory guideline requirements and client expectations as well as a brief summary of specific requirements in SANCO/3029/99 rev.4 11/07/00 on analytical methods used in support of ecotoxicology studies and present examples of different interpretations of these requirements by different clients.

Two Perspectives on Transfer of Residue Analytical Methods
Presented Kevin Clark with Leah Riter of Bayer Crop Science
8:35 a.m., August 28 in Ballroom 20B-D, Theater 3 | Click to add to Calendar
The transfer of analytical methods is often critical to either meet registration guidelines or enable efficient global business function. This presentation will outline the highlights and learnings from the recent transfer and GLP validation of a residue analytical method to enable registration of an agrochemical product from the perspective of both the method originator and the recipient. From the method originator point of view, key aspects of the transfer process include evaluating the business drivers for enabling external residue analysis, determining the robustness of a method to effectively transfer, writing clear and concise method SOPs to facilitate the transfer, and implementing post-transfer modifications. From the perspective of the method recipient, additional aspects of the transfer process include improving the functionality of complicated methods in production-scale use and determining realistic timelines for transfer and validation. In addition, an example of a collaboration and communication model, designed to ensure efficient and reliable transfers of complex analytical methods, will be presented.
