The MetaCarb™ line of carbohydrate columns provides high resolution columns for applications requiring high performance carbohydrate and organic acid analysis. These columns contain sulfonated polystyrene resins in the Calcium (87C), Hydrogen (87H), and Lead (87P) forms, and provide a wide range of selectivities for carbohydrate and organic analysis. They are widely used in the food and beverage industries for analysis of sweeteners, corn and cane sugars, fruit juices, soft drinks, beer and dairy products.

Bond Elut™ SAX is a strong anion exchange sorbent ideally suited for the extraction of compounds such as carboxylic acids, which may not retain effectively on weak anion exchange sorbents. The sorbent is supplied in the chloride counter ion form. You can modify the selectivity of the phase by replacing the chloride ion with other anions, such as acetate and hydroxide.

Supplier: VARIAN

PLgel Olexis is optimized for the analysis of high molecular weight polymers at elevated temperatures, particularly polyolefins and high performance polymers.

Supplier: VARIAN

Bond Elut™ C8 is very similar in properties to C18, but is not as retentive for non-polar compounds, due to its shorter hydrocarbon chain, and therefore reduced carbon loading. C8 is an excellent replacement for C18 when analytes are too strongly retained for effective elution. The potential for polar interactions is somewhat higher than for C18 because there is less coverage of the silica surface. These polar interactions are not, however, a significant property of C8.
