Polar, Hydrophobic Coating Stable, Long Useful Life Chemically and pH Resistant Click here for more information

These columns are an excellent choice when you need a slightly polar, hydrophobic coating of your capillary. Depending on the solutes characteristics, the CE200-HS may exhibit little to no wall interaction. The coating also allows for a wider pH range and may enhance chiral separations. These columns are compatible with all major commercial instruments and have a lot number printed on every package.

Weakly Hydrophilic Surface Low Hydrogen Bonding Reduce Wall Interaction pH 2 - 10 Click here to view applications Click here for more information and references

The coating on these capillaries (PEG) is weakly hydrophilic and exhibits low hydrogen bonding capacity. This coating will reduce the EOF allowing your solutes to separate based on mobility differences. These columns operate in a wide pH range and provide long, useful lifetimes. Compatible with all major commercial instruments they have a lot number printed on every package.

These columns are made from a high surface area (1,000 fold increase) capillary providing a reduced EOF and increased chromatographic interaction with the solutes. These columns can be used on any commercial CE unit. Care should be given to conditioning them as they must be handled differently than HPCE columns. Instructions are included with every shipment. A lot number is printed on every package.
