Development of online SFE-LC/MS system for analysis of metabolites in microbial cells

In bio-based fine chemical production, a short breeding cycle time of microbes is a key issue for improving productivity. Metabolomics has been widely used as a quick and comprehensive analytical procedure due to its excellent features of dynamic monitoring and quick evaluation for bio-production. On the other hand, sample pretreatment procedure is still generally tedious and time consuming while high-throughput analytical methods using LC/MS and GC/MS. We present the development of online SFE-LC/MS system that provides completely automated analytical process resulting labor-saving.
