Automatic Titration Using PC Camera in Volatile Basic Nitrogen Analysis by Microdiffusion Method

미량확산법에 의한 휘발성염기질소 분석에서 PC카메라를 이용한 자동적정

  • Published : 2005.01.01

Abstract

A PC-based automatic system was developed for automatic titration in volatile basic nitrogen analysis by the microdiffusion method. The system used a CCD-type PC camera for the automatic detection of the titration end point. The camera checked whether the green value of a pixel on the red image of titrated solution became greater than the red value. The data from the automatic titration using the system were not significantly different (p>0.05) from those taken by manual titration. The agreement between means of data from manual titration and those from automatic titration was good.

미량확산법에 의한 휘발성염기질소 분석에서 PC카메라를 이용하여 자동적정하기 위하여 자동적정시스템을 구성하였으며, 자동적정프로그램을 작성하였다. 자동적정방법은 피적정액 화상 중 마우스 포인터에 의하여 지정된 화소의 Green값과 Red값이 적정종말점에서 서로 반전되는 것을 이용하였다. 돈육시료를 사용하여 실험한 결과 부패도가 다른 모든 시료에서 자동적정과 수동적정간에 유의차가 인정되지 않았으며, 서로간에 높은 상관성이 있었고 잘 일치하였다.
