Antec Leyden has developed an integrated system solution for the analysis
of Bisphenol A in drinking water or beverages from polymer bottles. The system uses a 10-port
valve for automated sample enrichment to improve detection limits.
Bisphenol A
- Automated sample enrichment for better detection
limits
- Excellent reproducibility and linearity

water samples (3 upper traces) and standards (2 lower
traces: 0.5 and 1 nmol/L). Only water sample no 1
contained BPA (1.5 nmol/L).

ALEXYS
Bisphenol A |
For the analysis of Bisphenol A an AS 100 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 completely
maintenance free, and compatible with high modifier percentages. The ALEXYS system comprises the following parts:
- AS 100 autosampler with 10port valve, cool
- LC 110 HPLC pump (2)
- OR 110 organiser rack
- Clarity data acquisition software
- DECADE II electrochemical detector
- Flow cell with GC WE, HyREF
