Analysis of Plasticizer Contaminants in Beverages and Milk using an Automated System Based on Turbulent-flow Chromatography Coupled to LC-MS/MS

Instrument Type: LCMSMS

Phthalates are known endocrine disruptors that have been used to deliberately adulterate beverages and sports drinks in Taiwan. Phthalates and other plasticizers are ubiquitous contaminants particularly in fatty foodstuffs. Contamination arises from numerous sources such as the environment and food packaging. Cross-contamination with phthalates can easily arise during trace analysis in the laboratory and there are significant advantages in minimizing sample handling through online automated analysis. A method using online Thermo Scientific TurboFlow chromatography is presented.

TN62: Reducing Carbonate Interference in Anion Determinations with the Carbonate Removal Device (CRD): Trace Anions

Instrument Type: IC

Carbonate can interfere with accurate quantification of adjoining anions, such as sulfate. Here we show the efficient removal of the carbonate peak from a trace analysis water sample using the Dionex CRD 200 device. In this example, a large volume (1000 uL) of water spiked with < 4 ug/L concentration of 17 anions is directly analyzed.
