VDSpher® MS Column Line
Mass spectrometry is being used by an increased number of clinical laboratories to handle small sample volumes in order to detect and quantify very small concentrations of a given analyte such as Vitamin D2/D3, Immunosuppressants, etc. The HPLC column is an essential part of an LC-MS/MS configuration and needs to fulfill certain criteria:
- Particle size of 2.5 μm if a high resolution is needed.
- Particel size of 4.0 μm if the resolution is not an issue.
Since Mass Spectrometry is a highly sensitive method, very small impurities can be detected (e.g. due to carry-over effects), the VDSpher® MS phases were specifically designed in order to avoid these carry-over effects.
We are introducing 10 different modifications of the VDSpher® MS line.
The C18 phases can be used for a broad range of
- hydrophilic (C18-H, C18-LC-H) and
- hydrophobic (C18-DE, C18-B-DE) applications.
The non-endcapped phase C18-B shows a medium hydrophobicity.
In addition, we offer
- hydrophobic VDSpher® MS-Phases with C8, C4, Phenyl und CN- modifications.
The pore diameter of all VDSpher® MS-Phases is 100 Å and the column dimensions available are 30-150 mm length and 2.0 - 4.6 mm ID. Longer columns are available upon request.
