eluate n.【化學】洗出液。

elucidate

Many kinds of chromatograph including silica gel , d101 resin , sephadex l - 20 gel , rp - 8 and hplc are used in extracting and separating chemical constituents form these plants . certainly , they need to select the best eluate by tlc . some technique including ms ( ei - ms , fab - ms ) , id and 2d nmr ( cosy , roesy , hmbc , hmqc ) been used in identifying these chemical structures 通過各種硅膠柱層析,吸附樹脂, sephadex系列凝膠樹脂以及rp - 8類反向柱等層析材料以及高效液相色譜等技術,利用不同的洗脫體系對這兩種植物的化學成分進行分離得到純的單體化合物,然后利用ms ( ei - ms , fab - ms ) 、一維nmr 、二維nmr ( cosy , roesy , hmbc , hmqc )等技術對這些化合物進行結構鑒定,利用ir和uv對這些化合物進行了表征。

The eluate was evaporated , the residue was dissolved with 4 . 0ml of 0 . 1mol / l hcl solution , determine the 2nd derivative spectrum referring to o . lmol / l hcl solution Lmol l的鹽酸溶液4 , oml溶解剩余物,以0 lmol l的鹽酸溶液為參比,測定二階導數光譜圖。

Elution the removal of an adsorbed substance in a chromatography column or ion - exchange column using a solvent ( eluent ) , giving a solution called the eluate 洗脫:是用溶劑(洗脫液)將色譜柱或離子交換柱中的被吸附物質洗脫出來并排出洗出液的過程。
