| Abstract: | A series of ten biological tea, milk powder, chicken meat and reference materials including rice, wheat, corn, soybean, apple was prepared and certified. The freezing cabbage , spinach, and drying technique was used in sample preparation and a co-laboratory analysis scheme with 14 famous Chinese analytical laboratories was adopted in certification procedure. More than ten reliable analytical methods based on different measurement principles were adopted, of which ICP-MS, ICP-AES and INAA were taken as the primary analytical techniques. Total of 22477 determination data were collected and 5 136 average data sets were obtained. Values for fifty-nine elements were provided, among which fifty-four elements were certified. |
