Total Trace Metal Analysis
To improve the quality of the separation, SiliCycle manufactures silica gels with very low trace of metal content.
All silica gels are analyzed for more than 45 metals by ICP-MS down to ppm and reach up to 99.4 % silica purity.
This minimizes any issues from metal oxides that may act as Lewis acids and prevents «tailing» of most polar compounds (frequently ionizable) that can be caused by silica with a high metal content.
