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.

Thermo Scientific IonPac Guard Column AG7 4x50mm
An ion exchange guard column for ion chromatography with 4mm diameter and 50mm length containing inert polyvinyl polymer functionalized with quaternary ammonium groups to protect the analytical column from contamination and degradation by adsorbing anionic contaminants and strongly retained sample components, improving analytical column lifespan and performance when used inline before the column.
Hach Company Ohaus Moisture Analyzer Balance, 90g Capacity
Measuring moisture content has never been easier than with the MB90 Moisture Analyzer. The MB90's halogen heating distributes heat uniformly over the sample and speeds up the drying process, delivering fast and precise measurements. Designed for tool-free cleaning, its components can be easily removed for quick and easy maintenance. Operating the MB90 is intuitive with the icon-driven menu navigation on the touchscreen display.
