Unlike normal-phase chromatography, reversed-phase uses a hydrophobic stationary phase (e.g. C18 or ODS) and hydrophilic mobile phases (methanol/water, acetonitrile/ water). By converting silica’s active, polar silanols sites to neutral, lipophilic sites, compounds that will either aggressively stick to silica or not stick at all can be retained, separated and eluted using waterbased solvent systems.
Biotage SNAP cartridges are are made from medical grade materials and batch tested to ensure they meet stringent performance standards including efficiency (plate count) and peak symmetry. The Luer-lock connections operate safely at 100 psi without compression modules and can be used on any flash system. The SNAP design supports the greatest number of loading techniques available, including three different internal dry loading options. Dry loading the sample using Samplet® cartridges gives the best performance by eliminating any dissolution solvent effects.

3 internal dry sample load options
Internal dry loading improves sample purification by eliminating the problems associated with injecting samples dissolved in chromatographically strong solvents. This can be performed using either a pre-packed Biotage KP-C18-HS Samplet cartridge or with loose adsorptive media such as bulk Biotage KP-C18-HS or Biotage HM-N (diatomaceous earth).
- Prepacked Samplet® cartridge dry loading
- Self-packed Samplet cartridge dry loading
- Direct, on-cartridge dry loading
- 20% more loading capacity
- Higher peak resolution
