FIELD OF THE INVENTION

[004] The present invention relates to apparatus and methods for high-throughput analysis.

BACKGROUND OF THE INVENTION

[005] As an important part of chemistry, synthetic chemistry is the foundation of modern chemical industry. Although considerable progress has been made in theoretical chemistry and chemical engineering, trial and error method, which generally spends much time and effort, is by far still being used widely for screening pharmaceuticals, agrochemicals, catalysts and some novel materials.

[006] Combinatorial chemistry, emerged in the 1980s, made it feasible to synthesize thousands of samples with different compositions in a short time. Its application considerably shortens the products research period while various kinds of combinatorial techniques successively come forth. However, the existing problem is how to efficiently screen desired lead compound from large amounts of candidates. To solve this problem, various analytical methods, such as MS, chromatography, chromatography-MS, IR, NMR and UV-VIS etc, were chosen for sample testing in combinatorial chemistry. In general, these means were carried out serially which were yet inefficient, time-consuming processes. [007] To overcome the above-mentioned difficulties, some parallel analysis apparatus came into scene in recent years. By using these apparatus a good number of samples could be simultaneously analyzed in a very short time. But their exorbitant price and shortcoming in quantitative analysis hobble their applications. Therefore, more rapid, efficient and inexpensive multifunctional analyzing systems are required.

SUMMARY OF THE INVENTION

[008] The present invention provides a high-throughput analysis apparatus, which could realize high-throughput separation, qualitative and quantitative analysis of samples simultaneously, comprising: a sample introduction unit, a flow control unit, a separation unit, a detection unit, a signal collecting unit and a signal processing unit. The said flow control unit includes a flow splitter that could distribute one stream into a plurality of streams and the flow rate of each stream could be independently controlled.

[009] In another aspect, the present invention provide several methods of conducting high-throughput analysis using the same apparatus, such as a method of conducting the high-throughput analysis for screening catalysts, a method of conducting the high-throughput analysis for measuring the surface area of catalysts, a method of conducting the high-throughput analysis for inter-channels parallel measurement, a method of conducting the high-throughput analysis for compounds separation and measurement of the contents of a plurality of samples, etc.

[010] It could be seen from the following detailed description of this invention that the high-throughput analysis apparatus could conduct simultaneous high-throughput separation, qualitative and quantitative analysis of many samples in a short time, and it would be a great progress in combinatorial chemistry.
