PBDE determination by USEPA 1614
Posted: Sun Feb 23, 2014 4:54 am
Could someone share your lab experience in handling PBDE analysis by USEPA 1614 ？Any tips and tricks, in particular for BDE209 and other higher brominated DE? Thanks
I don't run that method exactly but I do analyze BDE209. What is your specific analytical issue with that compound? Phenomenex just recently released an application note on it's analysis using their new Semi-Vol column. It dramatically, according to their app note, increases signal and S/N for BDE209. I ordered a couple different dimensions of it but I haven't used it yet. https://phenomenex.blob.core.windows.ne ... 057d5e.pdf
I found BDE209 sensitive to injector and column temperature greater than 270°C and thus I use a PTV inlet for ramped temp volatilization. Also On-Column or On-Column-like injections can increase sensitivity of BDE209.
