SUBJECT: Polymer Identification on one material.
RECEIVED: One bag of light purple powder labeled “ABS Masterbatch”
POLYMER IDENTIFICATION ASTM D 3677-00 (2004)
Instrument: Perkin-Ekmer Clarus 500 Gas Chromatograph with a
Clarus 560D Mass Spectrometer
Accessory: CDS Analytical Pyroprobe 5000 Series
Column: Forte BPX5 GC Capillary Column
RESULTS:
SAMPLE
Poly I.D.
ABS Masterbatch
Acrylonitrile – Butadiene Styrene
Polyethylene
DISCUSSION :
An analysis of the resulting Chromatogram and comparison to the established NIST Library gives the following matches :
Time (min) Compound
2.32 1,3 – Butadiene
3.25 Acrylonitrile
9.74 Butadiene
11.35 Styrene
All of these represent indicator peaks for Acrylonitrile-Butadiene Styrene (ABS)
Chromatograms also matched the following :
Time(min) Compound
3.99 1-hexene
5.91 1-heptene
8.33 1-octene
10.87 1-nonene
13.33 1-decene
15.63 1-undecene
All of these represent indicator peaks for Polyethylene
As this was going to be a basic Polymer Identification, the instruments used were set up for qualification (identification) and not for quantification (%), however our estimate from analyzing the peaks from the Pyrolysis GC-MS is ABS with approximately 6 – 8 % polyethylene, with polyethylene most likely being the carrier for the purple color concentrate.
