查询词典 acetate

The water based food simulants,including deionized water,3％ acetate acid solution and 10 ethanol solution,were directly sampled into HPLC,while the refined olive oil needs to be successively extracted by hexane and methanol/acetonitrile mixture (volume ratio=1∶1) prior to sampling.

水基食品模拟物（去离子水、3%乙酸溶液、10%乙醇溶液）中的目标分析物可直接进样，精制橄榄油中的目标分析物依次通过正己烷和甲醇乙腈混合液（体积比1∶1）萃取后进样。

A migration detection method for 9 bisphenol type chemicals from food contacting materials was developed by using deionized water,3％ acetate acid solution,10 ethanol solution and refined olive oil as four food simulants. The chemicals included bisphenol A,bisphenol A diglycidyl ether,bisphenol F diglycidyl ether,and their derivatives.

倍他米松醋酸酯产生多晶型的原因是由于分子结构中活泼的羟基，在制备中产生的无定形和较低的温度是倍他米松醋酸酯水化物形成的重要条件。

Methods Sea sand were added into samples-distill by water in the condition of alkalescence vibratedly-add potassium ferrocyanide and zinc acetate (to deposit protein, faecula,fat.)-determination by HPLC after filtration.

样品加入海砂分散黏稠成块的样品，在碱性条件下用水振荡提取，加入亚铁氰化钾和乙酸锌沉淀蛋白质、淀粉和脂肪等，滤膜过滤进行液相色谱分析。

The protein and the fatty compounds in the sample are precipitated by zinc acetate and potassium ferrocyanide, then the chromogenic reaction of acetylacetone with formaldehyde released from the sample in weak-acid medium and boiling bath takes place immediately.

提出了一种用於现场测定水发食品中甲醛含量的样品快速前处理新方法，采用乙酸锌和亚铁氰化钾沉淀样品中的蛋白质和脂肪，在弱酸性介质和沸水浴条件下提取了样品中的甲醛，并与乙酰丙酮立即发生显色反应。

Methods: The protein and other impurity in the sample were precipitated by zinc acetate and potassium ferrocyanide after dipping of the sample. N,N-dichlorocyclohexylamine derived from sodium cyclamate by sodium hypochlorite in the filtrate was extracted by hexane. The HPLC separation was carried out with a phenomenex Gemini-C18 column using acetonitrile-water(7+3) or methanol-water (8+2) as mobile phase and detected by UV monitor at 314 nm. External standard method was used for quantification.
