WelchromTM XB-C18 |
| |
- High surface coverage and exhaustive double end-capping
- An excellent choice for general purpose C18 columns
- Excellent peak shapes for acids, bases and neutrals
- High performance over a wide pH range (pH 1.5 – 10.0)
- Best performance for separation of highly basic compounds, ideally for pharmaceutical compounds
- Exceptional batch-to-batch and column-to-column reproducibility
- Available in dimensions from analytical to preparative for all sample sizes

WelchromTM XB-C18 columns, featuring high surface coverage and exhaustive end-capping, are suitable over a wide pH range of pH 1.5 to 10.0 with enhanced stability for a wide variety of organic compounds. The bonding chemistry is optimized specifically for our base material. Our proprietary double end-capping leads to optimal performance with neutral, polar, acidic, basic, and chelating compounds. This phase, when used in mid pH, shows the biggest advantage in producing symmetric peaks for highly basic compounds, which normally exhibit peak tailing on other conventional C18 columns. WelchromTM XB-C18 will be your best choice as a general-purpose C18 column. |
