The extracted phenols were detected by an ods column , gradient elution and programmable uv wavelength detector 實(shí)驗(yàn)以ods柱為分離柱,采用梯度洗脫,可編程紫外檢測(cè)器進(jìn)行樣品檢測(cè)。
Anions and cations in sea water were separated and determined simultaneausly by the combining use of anion separation column ( and / or cation separation column ) with suppression - conductometric detection , and by the use of equi - grading and / or gradient elution 在試驗(yàn)條件下,利用陰離子和陽(yáng)離子分離柱,配合抑制電導(dǎo)檢測(cè),可以同時(shí)分離和測(cè)定海水中7種陰離子和6種陽(yáng)離子。
