Anion-Exchange Packed IC Columns
Metrohm USA METROSEP A SUPP 5 - 100
The Metrosep A Supp 5 - 100/4.0 allows highly efficient, rapid separations. This property makes the Metrosep A Supp 5 - 100/4.0 the standard column for short analysis times and the determination of anions which elute late (e.g., perchlorate).
YMC America, Inc Jsphr H80 grd 80A 4um 10x20mm
The J sphere series of columns consists of three kinds of ODS made from the same silica gel base each with a different ligand coverage The 4 um 80 silica support provides outstanding chromatographic efficiency while the high surface area material (500 m2/g) offers exceptional interaction with analytes This combination provides excellent peak symmetry across all J sphere products The variations in ligand coverage produce three columns with different hydrophobicity hydrogen bonding capacity and steric selectivity for tertiary structures Because of this J sphere can be used with confidence to identify structural differences of solutes and to improve the efficiency of separation optimization
Metrohm USA 5-250 ANION COLUMN
The high-performance separation column from Metrohm with an extremely high number of plates for the most demanding separation tasks. Even complex separation problems can be solved easily and reproducibly with the Metrosep A Supp 5 - 250/4.0. The high capacity of the column allows, for example, the detection of 1 �g/L bromate along with 150 mg/L chloride without sample preparation. The range of applications possible with this column far exceeds the detection of standard anions. The Metrosep A Supp 5 - 250/4.0 is the column of choice when it comes to reliable monitoring of the high purity standards in the semiconductor industry or of the boiler feed water of power plants.
