The developments of the last few months, with the extraordinarily sharp increase in raw material and energy costs, are also having a massive impact on VDS optilab GmbH. The situation has deteriorated to such an extent that we can no longer compensate for these renewed cost increases and have reduced our prices for HPLC Columns up to 10 mm inner diameter have to be raised by 5% and for columns from 20 mm inner diameter by 3%. Guard column cartridges and column accessories are unaffected by these increases. Please take this price adjustment into account in the printed prices in our HPLC column price list 2022. Thank you for your understanding!


VDS optilab is your sales & service partner for VICI Valco & VICI Jour products. We offer support for all questions about Valco switching valves.

VDSpher® MS Phases

Mass spectrometry is becoming more and more crucial as an online detection method. The requirements of the LC/MS analytics are reflected in the conception of HPLC columns. To reduce the solvent quantity and so as not to endanger the vacuum created in the mass spectrometer, columns of smaller dimensions are normally preferred. To profit from a high resolution further, silica gel with a small particle size is recommended for the column. VDSpher MS satisfies this requirement with 2.5 µm separation phases. If the resolution is not crucial, VDSpher MS columns with 4 µm silica gels are also available.

In principle, any VDSpher column can be used for LC/MS. Because as a sensitive detection method, mass spectrometry is in a position to display very low impurities, depending on the application e.g., carry-overs from previous runs (“carry-over effect“) VDSpher MS phases are selected specially to avoid these effects. In all, ten different modifications are available. The C18 phases enable a large bandwidth of hydrophilic (C18-H, C18-LC-H) and hydrophobic (C18-DE, C18-B-DE) applications. The not endcapped phase C18-B has medium hydrophobicity. Additionally, there are hydrophobic VDSpher MS phases with C8, C4, Phenyl and CN modifications.

The pore diameter of all VDSpher MS phases is 100 Å. Available modifications are displayed below:
