Analysis of herbicides using HPLC with low temperature evaporative light scattering detection
ثبت نشده
چکیده
This Application Note describes how the Agilent 380-ELSD Evaporative Light Scattering Detector was used to determine the effect of varying the evaporation temperature during the analysis of a mixture of herbicides with different volatilities. Phenylurea compounds are used extensively in agriculture as selective herbicides, however they are thermally unstable and degrade rapidly to isocyanates and amines, making analysis and detection difficult. The 380-ELSD provides a solution to the problems associated with detection of thermally sensitive compounds because it is designed to evaporate highly aqueous mobile phases at ambient temperature.

Simultaneous Determination of Four Active Ingredients in Sargentodoxa cuneata by HPLC Coupled with Evaporative Light Scattering Detection
A HPLC coupled with evaporative light scattering detection method had been developed for the simultaneous determination of 3,4-dihydroxyphenylethyl alcohol glycoside, salidroside, chlorogenic acid, and liriodendrin in the stem of Sargentodoxa cuneata. With a C18 column, the analysis was performed using acetonitrile and 0.2% formic acid aqueous solution as mobile phase in gradient program at a f...

Methods were developed for the separation, detection, and quantification of tocopherols and phytosterols by high-performance liquid chromatography with an evaporative light-scattering detector. Four tocopherolsa, fJ, y and o-and four phytosterols-campesterol, fJ-sitosterol, brassicasterol, and stigmasterol-were analyzed in soybean, sunflower, low-erucic acid rapeseed (LEAR) and com oils. The us...
متن کاملDirect analysis of artemisinin from Artemisia annua L. using high-performance liquid chromatography with evaporative light scattering detector, and gas chromatography with flame ionization detector.
Since the isolation of artemisinin 32 years ago, it has been analyzed by different chromatographic techniques. This work compared the analysis of artemisinin from crude plant samples by GC with flame ionization detection (GC-FID) and HPLC with evaporative light scattering detector (HPLC-ELSD). Data is also presented indicating that GC is suitable for the quantification of two of artemisinin pre...
متن کاملHPlC Analysis of Phospholipids by Evaporative laser light-Scattering Detection
oDays High-performance liquid chromatography (HPLC) for analysis of phospholipids has traditionally employed ultraviolet detection of the eluted compounds. The evaporative laser light-scattering detector (ELSD) offers new opportunities for quantitative analysis of lipids. Phospholipids were isolated from crude and degummed oils prepared from soyheans subjected to storage at high moisture conten...
