Silicone oil was analyzed using GPC K-806M, an organic SEC (GPC) column. For polymers such as silicone oil, which does not have UV absorption and small differences in refractive index with THF or chloroform, neither THF eluent nor chloroform eluent can be used. For the RI detection of silicone oil, therefore, toluene whose refractive index is significantly larger than that of silicone oil should be used as an eluent. Since the refractive index of silicone oil is smaller than that of toluene, negative peaks will appear when the detector polarity is normal position. Therefore, it is advisable to use reversed polarity to obtain positive peaks. Methylphenyl silicone oil which has UV absorption can be detected by UV detector with THF eluent.
