In the case of the Microbore version of the Metrosep A Supp 16 - 100, lower flows are applied through the smaller inner diameter. Eluent consumption is reduced drastically as a result. The dwell time of the ions in the detector becomes longer and the sensitivity or the peak area (with the same sample quantity) is increased accordingly. The Microbore separation columns are used together with the ...

Disinfection byproducts from water treatment are suspected not only of being health hazards but even of being carcinogenic. Oxyhalides have therefore become the subject of many investigations and standards (e.g., EPA 300.1 Part B, EPA 317.0, EPA 326.0). Of primary concern is bromate, which forms from bromide during the ozonization of drinking water. ...
