Anion separation column: Shodex, 250 mm x 4.6 mm Detector: Conductivity detector Eluent: 3.6 mM Na2CO3 Flow rate: 0.8ml / min Column temperature: 40 ° C Injection volume: 20ul ...
At present, the process of producing glyoxylic acid is glyoxal HNO3 oxidation method, maleic acid (maleic acid) O3 oxidation method and oxalic acid electrolysis reduction method. The advantage of glyoxal HNO3 oxidation is that the process is mature and the degree of glyoxal reaction is high. As the HNO3 corrosion equipment, combined with nitrogen oxides pollute the environment, affect the health o...
Determination of Inorganic Anions in Biobutanol Samples by I
1 Introduction Into the 21st century, the rapid development of the world economy, natural resources are consumed at a frantic speed. Some important resources such as oil and even the danger of depletion, the world is aware of the seriousness of the problem, have to study the product can be replaced. The current gasoline fuel alternatives to bio-butanol research and production of the most popular. ...
Simultaneous Detection of Inorganic Anions in DOPO by Autosa
Abstract: In this paper, chloroform was used as extractant, DOPO was dissolved, centrifuged and centrifuged, autosampler - two-channel ion chromatography was used to detect inorganic anions and cations in DOPO. The autosampler was used to synchronize with the dual channel. Greatly reducing the analysis time. Ion retention time RSD (n = 6) is 0.07% ~ 0.18%, peak area RSD (n = 6) is 0.43% ~ 0.88%. H...
