 Benzyl alcohol measured by high pressure liquid chromatography. Trigon depot, benzyl alcohol concentration in the original resuspended Trigon ampule; 0.22 μm Millipore and 5 μm Pall; benzyl alcohol concentration after the corresponding filter techniques; Sed 0.5 ml and Sed 0.9 ml, benzyl alcohol concentration after the corresponding sedimentation technique and pellet reconstitution with 0.5 or 0.9 ml of BBS; Cent 1 ml, benzyl alcohol concentration after the corresponding centrifugation technique. Bars are means of three independent assays performed in duplicate. Errors bars represent standard deviations. *Benzyl alcohol was statistically significantly higher in Trigon depot than in the techniques used to reduce the solvent agent (p<0.05).
