Detecting the Eight Kinds of Organic Solvent Residue in Paper by HS-GCIMS
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 ℃,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℃; programmed temperature:keep 2 min at initial temperature of 35 ℃,then rise to 100 ℃ at a rate of 10 ℃/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%.
