Headspace Analysis of Solvents in Printed Paper
Applications | | SCION InstrumentsInstrumentation
Printed paper products may contain residual solvents from inks and coatings that can affect product safety, performance, and regulatory compliance. Rapid and accurate determination of these volatiles is essential for quality control and risk assessment in packaging and printed materials
This application note demonstrates a headspace gas chromatography method with flame ionization detection to identify and quantify common solvents in printed paper substrates. The study aims to establish operating parameters and validate peak identification for routine laboratory analysis
Headspace sampling was performed using an HS injector coupled to a gas chromatograph equipped with an FID detector. Separation was achieved on a 30 m × 0.32 mm SCION-5MS column with 1.0 µm film thickness. The oven temperature program started at 45 °C for 12 min, ramped at 10 °C/min to 100 °C, and held for 8 min. Helium served as the carrier gas at 2 mL/min
Twelve solvent peaks were resolved and identified based on retention times: ethanol, iso-propanol, n-propanol, ethyl acetate, iso-propyl acetate, 1-methoxy-2-propanol, propyl acetate, an unknown compound, toluene, ethylbenzene, m/p-xylene, and o-xylene. The method provided clear separation and sensitive detection under the defined conditions
Advancements may include coupling headspace sampling with mass spectrometry for definitive compound confirmation, automation for high-throughput screening, and miniaturized systems for on-site testing in manufacturing environments
The reported GC-HS-FID method offers a reliable approach for monitoring solvent residues in printed paper, ensuring quality and safety in packaging applications
