Birch Plastics’ certified laboratory offers plastics resin identification testing services. This service is used mainly to check for contamination in parts or pellets. We use a Perkin Elmer FT-IR Spectrometer. This device can determine what ingredients were used to make up your sample. It can also conclude what type of fillers are used like talc, calcium and mica or if your plastic test sample has multiple materials, for instance, barrier resin in film like nylon or EVOH.
Plastic Identification Testing is only $75 per test sample
Please send us a small sample. A minimum of 5 grams is needed.
Once received, we will have the results within 48 hours.
After payment is received, a report will be emailed to you.

What is FTIR?
Fourier transform infrared spectroscopy, also known as FTIR analysis or FTIR spectroscopy, is an analytical technique used to identify organic, polymeric, and, in some cases, inorganic materials. The FTIR analysis method uses infrared light to scan test samples and observe chemical properties.
How Does FTIR Works?
Birch Plastics begins polymer identification projects by scanning the material with infrared spectroscopy (FTIR). This gives us a chemical fingerprint of the plastic which we can compare to a database of polymers.
The FTIR instrument sends infrared radiation of about 10,000 to 100 cm-1 through a sample, with some radiation absorbed and some passed through. The absorbed radiation is converted into rotational and/or vibrational energy by the sample molecules. The resulting signal at the detector presents as a spectrum, typically from 4000 cm-1 to 400cm-1, representing a molecular fingerprint of the sample. Each molecule or chemical structure will produce a unique spectral fingerprint, making FTIR analysis a great tool for chemical identification.
