FTIR(S) – Fourier Transform Infrared Spectroscopy

tl;dr – Fourier Transform Infrared Spectroscopy (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.

NIR(S) – Near Infrared Spectroscopy

nm – Nanometer

In the International System of Units, the prefix “nano” means one-billionth, or 10^-9  ; therefore one nanometer is one-billionth of a meter.

Cellofaan/ Cellophane

PPS – Polyphenylene sulfide

PI – Polyimide

PEI – Polyethylenimine

PP – Polypropylene
