ALEXYS Bisphenol A in water
Bisphenol A (BPA) is an important chemical building block that is used primarily to make polycarbonate plastic and epoxy resins, both of which are used in a wide variety of applications. Common examples of polycarbonate products include eyeglass lenses, digital media (e.g., CDs, DVDs), electronic and electrical equipment housings (e.g., personal computers, appliances, power tools), automobile headlight lenses, sports safety equipment (e.g., helmets, goggles), and reusable food and drink containers. For analysis of Bisphenol A an ALEXYS system is used in combination with a solid phase sample pre-concentration step. The chromatogram shows water samples and standards. Only water sample no 1 contained BPA (1.5 nmol/L).
- Automated sample enrichment
- Optimized for best detection limits
- Excellent reproducibility and linearity
- SenCell for best detection sensitivity
- Low solvent consumption with microbore HPLC
System configuration
For the analysis of Bisphenol A an AS 110 cool with 1 mL injection loop and a 10-port injection valve was used. The HPLC system uses an additional pump for sample enrichment on a pre-column. A 2mm column has been used at a flow rate of 200 uL/min which results in less chemical waste. A flowcell with glassy carbon electrode and HyREF was used for analysis. The HyREF is maintenance free, and compatible with high modifier percentages. The ALEXYS system comprises the following parts:
- AS 110 autosampler with 10port valve, cool
- LC 110S HPLC pump (2)
- OR 110 organiser rack
- Clarity data acquisition software
- DECADE II electrochemical detector, SCC
- Flow cell with GC WE, HyREF
