This webinar will discuss the development of offline solid phase extraction and novel analytical methods for trace analysis of organic microcontaminants in wastewaters. The laboratory uses the Autotrace 280 offline SPE to eliminate matrix interferences and concentrate a wide variety of contaminants. After sample preparation, high performance mass spectrometry techniques (e.g. UHPLC-Orbitrap MS/MS) are used to detect, identify, and quantify emerging contaminants (including endocrine disruptors, pharmaceuticals, and surfactants) in wastewater and drinking water. We will discuss how optimized sample preparation coupled to high-resolution accurate mass MS/MS facilitates detailed investigations of targeted and non-targeted contaminants at trace levels and will illustrate the application of this approach to gain an increased understanding of how emerging contaminants are transported and transformed within aquatic ecosystems.

Who Should Attend:
  • Researchers interested in learning about PPCP analysis
  • Waste Water treatment personnel who want to keep abreast of released contaminants
  • Regulatory officials who are considering potential regulatory action for these compounds
Key Learning Objectives:
  • Learn the latest techniques for automated, offline SPE.
  • How to remove matrix prior to high resolution MS
  • How these techniques are applied to complex waste water matrices
Nanomaterials exhibit exceptional physical and chemical properties, showing a great potential for employment in eg. personal care products, solar panels and medicine. Fullerenes are carbon based nanoparticles that have been applied at an increasing rate, leading to a growing concern about the human health and environmental effects. A complete analysis workflow applied to the analysis of fullerenes will be discussed.

Who Should Attend:
  • Environmental chemists interested in the analysis of carbon based nanomaterials
  • Environmental chemists interested in the analysis of emerging contaminants
  • Environmental chemist interested in water analysis in general
Key Learning Objectives:
  • Understanding the demands of this analysis
  • Learn about different workflows: LC-MS/MS vs LC-HRAM
Archived Event:
We’ve examined the occurrence and distribution of wastewater-derived and turf grass management organic contaminants in storm water retention ponds impacted by sewage-derived irrigation water and located on a coastal golf course community at Kiawah Island, SC.

Targeted LC-HRMS methods were developed for ~30 organic micropollutants including known xenoestrogens, pesticides, herbicides, and fungicides. Furthermore, a LC-HRMS/MS non-targeted screening workflow, utilizing a comprehensive, accurate mass MS/MS spectral library of ~1000 unique substances relevant to environmental systems, was implemented to monitor the occurrence of micropollutants for which compound specific instrumental parameters had not been developed.

In this webinar, learn how the identified compounds were quantified using an online sample preparation system coupled to a triple quadrupole instrument.

Who Should Attend:
  • Environmental chemists interested in wastewater or storm water irrigation
  • Chemists interested in saving time through online SPE
  • Chemists interested in learning about software workflow strategies for the identification and quantitation of emerging environmental contaminants.
Key Learning Objectives:
  • Use of HRAM to identify targeted and non targeted emerging contaminants
  • Use of EQuan MAX Plus Online SPE for sample treatment and preconcentration
  • Use of the TSQ Quantiva LC-MS to quantitate the ID’d compounds
