Simulated moving bed chromatography systems are designed, built and assembled completely at our us locations in naperville in illinois established in 1996, orochem technologies inc started as a biotech and chromatography company to manufacture unique sample prep technology products for the bioanalysis, drug discovery, and the genomics. The performance of simulated moving-bed reactor for two semicontinuous chromatographic reaction−separation processes, namely, isomerization of glucose to fructose (hashimoto et al, 1993) and inversion of sucrose to glucose and fructose (ganetsos et al, 1993), has been studied by mathematical modeling and numerical simulations. A key task of this project was to develop simulated moving bed ( smb ) chromatography systems based on fractal technology with the goal of significantly reducing the size and cost of such systems applied to biomass processing.

Simulated moving bed (smb) technology is a continuous chromatographic technique proven to have many advantages compared to conventional batch chromatography, such as: raised productivity and product concentration, reduced buffer consumption as well as more efficient use of raw material. Simulated moving bed chromatography (smbc) has emerged as a significant separation technology in the chemical, pharmaceutical, and food industries the smb operating parameters are chosen to satisfy various performance objectives such as maximization of purity or productivity and the choice of the objective is generally guided by process economics. Simulated moving bed (smb) technology is an intriguing innovation that has been exclusively applied to the puri- fication of different types of products ranging from. Uop's rotary valve insures sorbex unit reliability and high on-stream factor the sorbex™ family of processes utilize stationary, multi-bed adsorbent chambers in a unique process configuration to simulate moving bed, counter-current extraction. Simulated moving bed (smb) chromatography is a continuous purification technique that has higher throughput and requires less solvent than regular batch chromatography even for difficult separations, it can achieve high yield and high purity at a reasonable production rate.
Simulated moving bed technology: old and new the aim of this work is to present some relevant examples of smb separations corresponding to the two major ages in the use of the smb concept, here named old and new applications. Simulated moving bed (smb) is a continuous chromatography that is highly efficient in the separation of binary or complex mixtures - only requires 1/5 of solvent consumption compared to traditional single column chromatography. Extra info for simulated moving bed technology: principles, design and process applications sample text it is obvious that a system with more columns per section will be more expensive.
