An overview of the benefits of using a Microwave Plasma Atomic Emission Spectrometer for the analysis of low conc elements in soils, after DTPA extraction.
determination of micronutrients Cu, Fe, Mn and Zn in soils following DTPA extraction using the Agilent 4210 MP-AES instrument.
MP-AES proved to be an ideal alternative to AA spectroscopy for the analysis of elements in river sediments, demonstrating excellent accuracy and stability.
安捷倫在危廢鑒別、常見固廢/危廢處置及資源化利用等環(huán)節(jié)的理化分析及相關(guān)環(huán)境監(jiān)測領(lǐng)域中，積累了大量經(jīng)驗和應(yīng)用方案。
本研究開發(fā)了基于QuEChERS 前處理結(jié)合氣相色譜- 三重四極桿串聯(lián)質(zhì)譜檢測土壤中227 種農(nóng)藥殘留的高通量方法。對QuEChERS 前處理的提取方式、提取時間、緩沖鹽、凈化條件等參數(shù)進行了優(yōu)化，在最優(yōu)條件下進行了方法學(xué)考查。結(jié)果表明：227 種農(nóng)藥在2-200μg/L 的范圍內(nèi)，線性良好，絕大部...
