Detecting the Eight Kinds of Organic Solvent Residue in Paper by HS-GC/MS

Abstract:

A method is established to determine eight kinds of residual solvents in paper package by HS-GC/MS, such as benzene, toluene etc. Response surface method is used to optimize pretreatment temperature and time, the terminal pre-temperature is 100 °C, with time 40min. The result reveals that the pretreatment-temperature has a significant impact on peak area and pretreatment-time has no significant influence. The residual solvents in sample was separated using HP-5MS chromatographic column; Flow velocity of He:1ml/min; Inlet temperature:250°C; programmed temperature: keep 2 min at initial temperature of 35 °C, then rise to 100 °C at a rate of 10 °C/min and keep 3min; the total time is 14.5min. The eight kinds of residual solvents can be effectively separated by this method. The linear range was 0.330~7.956mg/m2 and the correlation coefficient was between 0.995~0.999.The Recovery rate was 99%~114.8% and the relative standard deviation (n=5) was 0.916%~1.333%.
