How to minimize carryover with a new washing method

Carryover is the appearance of a small sample peak when injecting a blank after the sample. It is caused by sample residues which remained in the system after the preceding injection. One significant factor for carryover is the injection mode used. In this study it was investigated to what extent the carryover correlates with the number of subsequent washing steps. Both the wash volume and the properties of the wash solutions have a significant effect on sample carryover. Sample carryover was reduced to less than 0.003 % for the analytes, caffeine and chlorhexidine.
