IC Guard Columns and Cartridges
MilliporeSigma™ Supelco™ Chromolith™ Guard Cartridge Holder
The Chromolith™ 5-2 guard cartridge holder bioinert is suitable to connect any Chromolith™ guard cartridge to an analytical Chromolith™ HPLC column.
Thermo Scientific AG14 GUARD COLUMN 4MM
IonPac AG14 Guard Column, Dimensions:4 x 50 mm, Maximum Operating Pressure: 27.6 MPa (4000 psi), Mobile Phase Compatibility: pH 2-11; 0-100% HPLC solvents,Bead Diameter ( micrometer): 9.0 micrometer, Pore Size: 100 angstrom, Crosslinking (%
Metrohm USA METROHM CAUTION GUARD COLUMN
The Metrosep C 4 Guard/4.0 contains the C-4 column material and is used to protect all Metrosep cation columns that have a substrate based on silica gel. Particles and contaminations are reliably retained, allowing the lifetime of the analytical separation column to be prolonged considerably. The economical price is an additional plus. The Metrosep C 4 Guard/4.0 also functions according to the "On Column Guard System" and is screwed directly onto the separation column with nearly no dead volume.
Thermo Scientific AG11 ANION GUARD COLUMNS
IonPac AG11 Guard Column, Size:4 mmx 50 mm, Provides fast analysis of inorganic anions and organic acid anions, including polyphosphates, using hydroxide gradient elution
Thermo Scientific GUARD COLUMN IONPAX AG9-HC
IonPac AG9-HC Guard Column (4 x 50 mm), Maximum Operating Pressure: 4000 psi, Mobile Phase Compatibility: pH 0-12; 0-100% HPLC solvents, Bead Diameter: 9.0 micrometer, Pore Size: 2000 angstrom, Crosslinking (%DVB): 55%, Functional Group: Al
Metrohm USA A SUPP 16 GUARD 4.0
The Metrosep A Supp 16 is the high-capacity version of the Metrosep A Supp 15 and is also based on a surface-functionalized polystyrene-divinylbenzene copolymer. The functional groups are bonded covalently. The morphology of the anion exchanger results in unique selectivity. In addition, this column type is noteworthy for its high mechanical and chemical resilience. The column is well-suited to applications with a high ionic load but which require only relatively low resolution. Using the Metrosep A Supp 16 - 100/4.0 to determine bromate in water by means of the triiodide method (EPA 326, DIN EN ISO 11206) is another of its numerous applications.
