Development of soybean certified reference material for pesticide residue analysis

Proficiency testing by the National Metrology Institute of Japan for quantification of pesticide residues in grain samples from 2012 to 2018

“…These target pesticides described in Table 1 were selected because they are widely used in Japan and most of their stabilities have been confirmed. [11][12][13][14] The grains, such as brown rice, wheat, and soybean, were selected as food matrices because little other PT has been performed by using grains, despite the fact that a large amount of grain is consumed in the world. Our PT program has three advantages 9) : 1.…”

Electrochemically pretreated zeolite-modified carbon-paste electrodes for determination of linuron in an agricultural formulation and water

“…Many analytical methods have been applied to the analysis of pesticides, and most are based on separation by gas or liquid chromatography [9][10][11][12][13]. High-performance liquid chromatography (HPLC) is preferable for phenylurea analysis [14][15][16].…”

Development of Analytical Reference Material for Proficiency Test of Pesticide Multi-residue Analysis in Tomato

“…무작위로 선별된 10 bottles의 상-중-하 위치에서 분석하 여 균질성을 확인결과는 Table 4와 Table 5와 에   자유도(degree of freedom)와 p=0.95일 때(95% 신뢰수준) Student's t-factor의 값을 곱한 값보다 작을 경 우에 불안정성이 관찰되지 않은 것으로 판단하였다 (Otake et al, 2013, Yarita et al, 2014.…”

“…그 중, 농산물에 잔류하는 농 약의 농도는 매우 미미한 수준이기 때문에, 이를 분석하는 장 비의 적합성 또는 분석자의 숙련도 차이는 잔류분석의 결과 에 매우 많은 영향을 미친다. 농산물 내 잔류농약분석 결과의 신뢰성과 일관성을 확립하기 위해 국제적으로 다양한 매트릭 스를 사용한 농약다성분 인증표준물질이 개발되고 있다 (Otake et al, 2009;Sin et al, 2012;Otake et al, 2013;Yarita et al, 2014;Grimalt et al, 2015). •…”
