Dear ACS members
Due to previously I posted fully details stated ( consult spectra analyze of SSNMR ) upload to ACS network till to now still nobody reply,
because SSNMR are the reliable instrumentation for identification , but three of university professor has inconsistence result
and the sample related organic chemistry, I think only chemical identify method can find out what material created the sample
Recently I sends the sample to Hong Kong Baptist University Chemical Testing services for GC-MS identification and got
the result but still haven't concrete conclusion, so I want consulting with to ACS members, the below GC-MS report
can shows the sample are the synthesis man- made product = common plastic ?
Now physical data , SSNMR spectra, if interesting please search ACS network ( consult spectra analyze of SSNMR ) , in this stage I only want to
clarify the sample are the natural or man-made product, the GC-MS report as below:
Thanks to ACS Chemist & members , for yours help I deeply appreciate from the bottom of my heart !

The GCMS screening by Dichloromethane as extraction solvent. The screening result as below:
Retention Time (min)
Phthalic acid, monoethyl ester
2-Aminoacetic acid, N-[4acetylphenyl]-
There are major 13 peaks was found from screening.
4 compounds could match with our library ( Matching quality > 80%).
Since the file of each mass spectrum is too large, It would be send to you with the full report. The full report will send to you in this week.
