Automotive catalysts are controlled by the specifications of the automakers. Typically the cost of catalyst comprises one or two percent of the cost of commodity manufacture. This latter idea is particularly powerful in an industry where margins are eroding. Thus the incentives for new catalyst applications lie, again unlike commodities, in new products and processes. Opportunities to introduce new materials arise only as new contracts open, either at the expiration of an old contract or for a new product.
Any sequential system is by definition slower than a simultaneous method.
Simultaneous methods, however, require multiple detectors and cost and physical size constraints restrict them to a small number of simultaneous determinations. This drives the science to fast sequential methods. In any sequential method, analytical response time is the critical parameter. Only optical signals approach instantaneous readout. Relationship between method of library generation and replication - Actually less of a problem in materials than in bilogical systems.
