报告题目：Analytical Strategies to Assess PFAS Removal and Lifecycle Fate during Adsorption or Transformative Water Treatment Processes
报告摘要
Per- and polyfluoroalkyl substances (PFAS) occur in ground and surface water sources across the globe, and proposed drinking water regulations are driving PFAS treatment technology development and implementation. This presentation will first address current treatment technologies, which utilize adsorption (liquid to solid phase transformation), membranes (liquid to liquid separations) or transformative (oxidation or reduction) processes. Examples will be provided how treatment process efficiencies for “real waters” and how the processes challenge analytical methods. Second, the presentation addresses end-of-life for residuals (e.g., activated carbon) that contains PFAS, which will require incineration. Tracking PFAS during incineration requires unique analytical approaches to track fluorinated aqueous, gaseous and solid-phase species. Overall, the presentation will demonstrate how to match PFAS analytical strategies to PFAS drinking water treatment processes.

报告题目：False positive, negative, and unexpected Drug Testing Results in the Urine Toxicology Laboratory |药物测试：尿液毒理学实验室使用筛选法（免疫测定法）和确认法（MS）
报告摘要
In 1995 I co-authored a short article entitled “False-positive Immunoassay Results for Urine Benzodiazepine in Patients Receiving Oxaprozin (Daypro)”. This was published when rapid urine drug screening test methods were first becoming available. The laboratory community was starting to realize that not all assays can be tested for all of the thousands of drugs, substances or endogenous compounds that may potentially cause result errors.
There are false positive, false negative and unexpected patient urine drug test results that occur in the Urine Toxicology laboratory.
How does one research these results and assist the clinician in helping to assess these results to treat their patient?
Unexpected urine drug test results can occur during any phase of the testing process; however, the most common usual results occur during the pre- analytical or patient collection phase. During this phase patients can provide “fake” urine, take substances that can affect the testing method, or they can adulterate/dilute their urine specimen.
Depending on the screening test method used, the test method can be impacted by a variety of substances that can produce either false negative, false positive or usual results. Screening results can also be different than the confirmation results making interpretation of patient results even more confusing.
During this presentation we will review a basic screening test method and confirmation method. And discuss some of these unexpected urine drug test results.

报告题目：Certified Reference Materials for a Global Greenhouse Gas Monitoring Infrastructure
报告摘要
Understanding sources and sinks of Greenhouse Gases (GHG) and the impact of policies to mitigate emissions provides a key tool for action against Climate Change. GHG emissions and uptake can be determined through measurement systems that include in situ measurement of GHG concentration at varying levels of spatial distribution. These measurements together with wind-speed measurements and numerical weather prediction and dispersion models can be used to determine spatially and time resolved GHG emissions and sinks. Maintaining a global system of such measurements, as envisaged, for example, by the WMO initiative on a coordinated global Greenhouse Gas Monitoring Infrastructure, requires close attention to quality assurance and equivalence of measurements from different sites. Significant emissions may lead to small changes in GHG concentration, requiring highly consistent calibration standards at different measurement sites. The presentation will cover the establishment and characterization of CO2 in air standards for the measurements of concentration as well as isotope ratio, for source apportionment, that are required in GHG measurement networks. Generating the highest precision measurements of CO2 in air requires adopting metrological traceability to defined sets of primary standards, the so-called scale approach. The conversion of CO2 in air amount fraction values from one scale to another requires the scale relationships to be well known, noting that the requirement for internal consistency of standards within a scale, such as the WMO-CO2-X2019 scale, is at the 0.01 μmol/mol level, and consistency between different scales should not exceed the 0.02 μmol/mol level [1]. Certified reference materials that are needed to calibrate both in-situ based optical/laser based GHG amount faction and isotope ratio measurements as well as mass spectrometric laboratory-based measurements of isotope ratio will be described, as well as on-going comparisons to verify their equivalence. These comparisons are supporting National

报告题目：Development of a New Ionization Source for Single Cell Metabolome Analysis
报告摘要
Although the unrevealing of cellular heterogeneity is limiting for the understanding of complex processes in cancer research as e.g. its influence on the process of metastasising, current research still depends on bulk analysis technologies as no reliable method could be established for real single cell metabolome analysis yet.
The necessary analytical requirements that such a method for single cell metabolome analysis needs in terms of detection limit, sample amount and specificity will be discussed in detail in this presentation. Also, still unsolved problems will be addressed and put up for discussion.
Subsequently, our current work on an ion source, which should be able to destroy the cell and thus release the analytes and ionize them by means of Dielectric Barrier Discharge, will be presented. The current status of developments from the literature and from us will be briefly presented in this talk.
