This application has been developed to determine all the common sulfur species, in exception of sulfate, via ion exchange chromatography. The aims of the application development have been achieved using perchlorate as a mobile phase and utilizing direct UV absorption as detection technique.

Sulfur speciation in mining leachates

Health and safety pressures are motivating the gold mining industry to develop a substitute to cyanide leaching processes. The drive is mainly based on the high toxicity of cyanide. The chemistry involved in the thiosulfate leaching process is more complex and less robust than the cyanide leaching process. It is,...

To determine deficiencies in intestinal permeability, the lactulose/rhamnose (L/R) intestinal permeability test is widely used.

Verification on lactulose – rhamnose intestinal permeability in blood serum

To determine deficiencies in intestinal permeability, the lactulose/rhamnose (L/R) intestinal permeability test is widely used. This barrier function test is based on the comparison of intestinal permeation of a larger molecule with that of a smaller molecule by measuring the ratio of these molecules in the blood serum. The two...
