Columnas de cromatografía

Las columnas de cromatografia separan las moléculas de mezclas gaseosas o líquidas. Las columnas preempaquetadas rellenas de fase estacionaria reducen el tiempo de preparación. Las columnas de cromatografia pueden soportar temperaturas extremas y fluctuaciones de la presión que suceden cuando la fase mobil es empujada a través del medio. Estas columnas estan disponibles para procedimientos analíticos y preparativos para separar componentes según su polaridad, composición o tamaño.

Cogent Diamond Hydride™ HPLC columns, MicroSolv Technology Corporation

Cogent Diamond Hydride™ HPLC columns, MicroSolv Technology Corporation

Supplier: MICROSOLV TECH CORP

These useful HPLC columns have a silica hydride surface similar to other TYPE-C™ phases but the uniqueness of Diamond Hydride™ is that they have a very small amount of carbon on the surface that adjusts the hydrophobicity to a small but important level. This is an excellent choice for small, polar compounds by LCMS or HPLC.
