產(chǎn)品詳細(xì)介紹
The IAEA-359 Cabbage material was grown from seed in the vicinity of the IAEA laboratory in Seibersdorf, Austria. Since this material was originally intended for use as an agrochemical reference material, the seeds were treated with Lindane and Aziprotryne and during the growth of the crop, it was treated with a further eight agrochemical compounds (Metazachlor, Propachlor, Desmetryne, Endosulfan, Bromophos, (Lindane), Fluazifop-butyl, Bitertanol and Trifluralin). The raw material was oven dried at 40°C for several days. The dried cabbage was ground in an impact pulveriser mill to pass through a 300 μm sieve and then further processed in an air jet mill, resulting in a particle size below 50 μm. This material was γ-sterilized at 25 KGy using a Co-60 source to ensure long-term stability of the material by inhibiting microbial action.
