Dima Technology established solid phase extraction-high performance liquid chromatography for the determination of Sudan red in duck egg yolk. The duck egg yolk sample was extracted with n-hexane and purified by ProElut SDH Sudan Red detection special solid phase extraction column and detected by high performance liquid chromatography. 1. The method uses the national standard method for sample extraction. The purification process uses a commercial solid-phase extraction column for Sudan Red detection. It is not necessary to carry out column packing and neutral alumina activity adjustment according to the national standard method. The activity of alumina is easily affected by the environment and causes the instability of Sudan red recovery rate. 2. The use of ProElut SDH Sudan Red detection special solid phase extraction column reproducibility and recovery results are more stable and reliable; 3. Method detection limit 10 μg/kg, which is the same as the minimum detection limit required by the national standard GB/T 19681-2005.
Stainless Steel Pots are made from high-grade 18/8 stainless steel. This material is food grade, non-toxic, durable and easy to clean.
Our Stainless Steel Pots are mostly Stainless Steel Vacuum Water Pots. They have a double-wall vacuum treatment, so they can ensure your drink keeps as it is. And you don't need to worry about getting your hands cold or hot.
Stainless Steel Single Wall Pot has a single wall. It sacrifices thermal insulation and improves portability. Holding it in your hand all the time will not cause any discomfort.
