I am injecting sugar standards and tobacco samples on HPLC-RID. The standard is prepared in pure water and the sample is extract in pure water. When I compare the peaks found in the standard vs sample, there is a slight shift of about 0.1 min in the sample. Why is this even though diluent is the same?
