Offline lab analysis usually requires samples to be taken manually, with significant delays of up to several hours before they are analyzed in the lab. There is also the risk of alteration prior to analysis. All this makes it harder to control the process.

Online process analytics can be worthwhile with as little as one analysis per day. Compared to lab analysis, its particular appeal lies in having measured values available quickly, with no interruptions or lengthy transit times. Process analyzers are perfectly adapted to the special requirements of the chemical industry and make a substantial contribution toward both optimization and efficiency improvement in chemical plants. Siemens Analytical Products and Solutions offers end-toend system solutions for process analytics.
