Gas chromatography - What are Columns?
Liquid and gas chromatography instruments wouldn't work without columns. Both liquid and gas chromatography analyze samples by separating them into their individual chemical components. A column, a long tube lined with specialized chemicals, is required for this process as it forms part of the instrument which performs the separation. When a sample makes its way through the tube, certain ...

Water analysis: bromate round robin test confirms superiority of the triiodide method
Bromate is a potential carcinogen and is generated by the oxidation of bromide traces during water disinfection by ozonization. A recently conducted round robin test has confirmed ion chromatography followed by post column reaction and ultraviolet detection to be a superior method of detection. Moreover, this method (draft ISO/DIS 11206) compares favourably with the former standard method (ISO ...
