In general, modern chromatography liquid autosamplers accept 12 x 32mm vials, so we will assume that a 12 x 32mm vial is compatible with your autosampler (Headspace autosamplers accept 20mm wide autosampler vials). Here, we have outlined the simple steps in selecting the best chromatography vial for your analysis.
Superficially porous particles (SPPs) have a solid core surrounded by a thin, porous shell rather than porous throughout the entire particle, as is the case in traditional, fully porous particles. The solid core limits diffusion distance and improves separation speed. Superficially porous particles also have a narrow particle size distribution, improving efficiency and resolution. Another advantage of superficially porous particles is they can be used on both HPLCs and UHPLCs. Because of the variety of phases now available and the compatibility with both new and older HPLC systems, superficially porous columns are many chromatographers’ first choice when developing a new HPLC method.
