dmso for solvent

On Sunday i will go to the lab to run a new method for us. today i took a quick glance at it and i saw that the solvent is DMSO/MEOH 90:10. I don't recall the analyte's name but the m.phase is a typical buffer/ACN isocratic and a C18 100x4,0 column. As i have never seen such a solvent before, i thought i would ask the forum for any recomendations (something is likely to bother me this Sunday?), because it is the first time we are doing this method, and it's Sunday, and noone would like me to fail.

A typical silica-based C18 column will have no problems with DMSO as sample solvent. Be warned, though, that due to its high viscosity you might see a significant pressure pulse upon injection.
