Varian PrepStar SD-1 and SD-2

Two scale-up formats cover the full spectrum of sample types. High efficiency systems separate complex samples using small particle sorbents (5-10 µm) to deliver milligram to gram quantities of pure product (SD-1). High-throughput systems use larger particle sorbents (10-25 µm) with column overload strategies to deliver gram to multi-kilogram quantities of pure product in more economical platforms (SD-2).
