Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS) and Fourier transform infrared (FT-IR) spectroscopy were used for characterizing specks in cellulose pulp, polymeric materials and pitch formed during the cellulose extraction and paper production in the Brazilian mill. Three samples were analyzed and the pyrograms and infrared spectra obtained were compared. The results showed that the analytical pyrolysis more effectively differentiated between impurities (dirt specks) when compared to the infrared spectroscopy.
热解气相色谱-质谱联用仪（Py-GC/MS）和傅里叶变换红外（FT-IR）光谱仪被用于表征巴西工厂在纤维素提取和纸张生产过程中形成的纤维素浆、聚合材料和沥青中的斑点。分析了三个样品，并比较了得到的热解图和红外光谱。结果表明，与红外光谱相比，分析热解能更有效地区分杂质（污垢斑点）。
