You can use gas chromatography to analyze Bisphenol A, but you must derivatize it first.  It does not chromatograph well in its natural form.  I typically use BSTFA/TMCS to convert the compound to its di-TMS analog.  I've attached a publication summarizing the procedure for analyzing Bisphenol A with this derivatization approach.  I hope this helps.

Hi, at our Lab. we apply GC FID/MS for analyzing it:

Analysis was performed using GC-FID with Agilent Technologies 6890N and GC-MSD 5973 series equipped by Willey 7n.1 database (2004),on HP-5 column (30 m x 0,250 mm x 0,25 µm).Inlet temperature was set at 250 C, split ratio 50:1, flow rate 1mL/min (He), oven temperature was programmed from 100 C-250 C, 50C/min for 30 minutes analysis. Transfer line temperature from oven to detector was 280 C; energy of ionization was set at 70 eV.

I've run it using GC-MS many times without derivatization. Conditions were similar to those that Dr. Indrayanto indicates.

 Dear sir, 

thank you very much indeed for your valuable answers and provided paper. it was really helpful and i do really appreciate it 

I wish to express my opinion. Surely Gas-Chromatography (GC) with FID is the quantitative method if high-recovery analysis from the column is achieved.

However, development for the high-recovery separation (choice of adequate gas-eluent) seems to be difficult as compared to HPLC-photometric method.

I am currently trying to run it on GC-FID. We have found it does not need to derivatized (tried it both ways and the only difference seems to be that it shifts slightly to the left when not derivatized. Areas are more or less the same).

What I am having trouble with is that I seem to get carryover from the BPA. I have done front end maintenance on my injector (septum change, liner change, gold seal change and trimmed about a meter off the column which is a ZB5-MS+).

My split is 5:1. If I have any BPA in a sample it tends to hang around after the initial injection, especially if that sample was particularly high in BPA (~100 ppm). I have run mulitple blanks after a BPA containing sample and you can watch the BPA content decrease with each injection, like it is being washed away each time. My program is 31.5 minutes long starting with 50'C @ 2 min then a 10'C/min ramp to 325'C and 2 minute hold. Have not yet tried a longer hold.

I am trying it on the GCMS at this point but I am wondering if anyone else has experienced carryover and what you did about it.
