We have constructed a second generation instrument for performing automated thin layer chromatography (TLC). The TLC instrument consists of four dedicated stations for 1) plate dispensing, 2) sample application, 3) plate development, and 4) densitometry. A robot is used to move TLC plates among stations. The TLC instrument functions either as a stand-alone unit or as one analytical module in a robotic workstation for synthetic chemistry. An integrated hardware and software architecture enables automatic TLC analysis of samples produced concurrently from synthetic reactions in progress on the workstation. The combination of fixed automation and robotics gives a throughput of 12 TLC samples per hour. From these results a blueprint has emerged for an advanced automated TLC instrument with far greater throughput and analytical capabilities.
