The standard for the ingredients in refreshing drinks as specified in the Food Sanitation Act states
that arsenic should not be detected. Therefore, for the purpose of quality control, the analysis of
arsenic is being performed. ZA3000 series instruments employ the polarized zeeman method as the
BKG correction method even for the hydride generation method and it is possible to perform accurate BKG corrections and also to analyze arsenic with an extremely stable baseline. The result of the
spike recovery test indicates that arsenic in drinks can be correctly analyzed.
