This innovation is crucial for laboratories focused on peptide and protein bioanalysis, where precision and throughput are paramountEnhanced separation in ambient mass spectrometry imaging.
The iKey HT separation devices are available in various configurations, primarily distinguished by their stationary phase chemistry and pore size. Two prominent types are the BEH C18 and CSH C18 phases, both designed for reversed-phase chromatography, a common technique for separating peptides based on their hydrophobicity.
* BEH C18 (Ethylene Bridged Hybrid): This widely used material offers excellent chemical and physical stability, making it suitable for a broad range of pH conditions作者：F Cozzolino·2020·被引用次数：24—Peptidemixtures were separated onpeptideBEH C18 130Ǻ, 1.7μm, 150 μm x 50mm,iKeyby using a linear gradient of eluent B (95% acetonitrile .... The 130 Å pore size is particularly well-suited for peptide separations, providing good retention and resolution.
* CSH C18 (Charged Surface Hybrid): This phase offers unique selectivity, especially for peptides with charged or polar characteristics, by incorporating a weak anion-exchange functionality. This can be advantageous for resolving complex peptide mixtures that might co-elute on purely hydrophobic stationary phases.
* HSS T3: Another variant, the HSS T3 (Hydrophilic-Silica) phase, provides a different selectivity profile, often used for highly polar analytes or when a broader range of compound types needs to be analyzed.
The "HT" in iKey HT signifies "High Throughput," indicating that these devices are optimized for increased sample throughput作者：RE Foreman·2023·被引用次数：8—TheionKey HSS T3 Separation Device(100 Å, 1.8 μm, 150 μm × 50 mm, Waters) was set at 45 °C, and the analytes were separated over a 13 min .... This is often achieved through features such as a 300 µm internal diameter (I.D.) separation channel, which allows for faster analysis times and reduced solvent consumption compared to narrower channels, while still maintaining high sensitivity.
The design of the iKey HT separation device offers several significant advantages for peptide analysis:
* Integrated Design: By integrating the separation channel and often the emitter into a single unit, iKey devices eliminate dead volume associated with traditional column connections. This leads to sharper peaks, improved resolution, and enhanced sensitivity.
