ZirChrom Separations
 
ZirChrom Separations (USA) manufactures a full line of LC/MS friendly, ultra-durable zirconia and titania-based (HPLC) stationary phases. Columns packed with ZirChrom phases offer unique chromatographic selectivity coupled with the high efficiency, low back pressure and excellent pore structure of rigid inorganic supports. 
 
Zirconia, or zirconium dioxide (ZrO2), is a metal oxide that can exist in a number of crystalline and amorphous forms. The primary advantage of zirconia relative to conventional silica-based phases is its unique chromatographic selectivity combined with extreme chemical and thermal stability. Zirconia is thermally stable at column temperatures as high as 200 °C, and is chemically stable over the entire pH range from 1-14. The extreme stability of zirconia and its unique chromatographic selectivity allows for the optimization of separation conditions, which are totally incompatible with other types of supports. 
 
ZirChrom phases:
ZirChrom®-PBD, ZirChrom®-PS, DiamondBond®-C18, ZirChrom®-CARB, ZirChrom®-EZ, ZirChrom®-MS, Sachtopore® Titania-Based, ZirChrom®-SHAX, ZirChrom®-WAX, ZirChrom®-WCX, ZirChrom®-PEZ, ZirChrom®-SAX
