| Abstract: | In the measurement of the formaldehyde in the beer,the dependability of determining will reduce due to the influenced factors in- cluding reagent water,pH value,acetyl aceton,heated temperature,chromogenic time and sample pretreatment influenced the blank-value. In this paper,the influenced factors have been discussed thoroughly and new countermeasure has been proposed to increase the dependability. |
