Differences between process analyzers and laboratory analysis

2 Differences between process analyzers and laboratory analysis 

Several attribntes distingnish process analytical methods from classic laboratory analysis. Most prominent are those differences that refer to the direcmess of the analysis in the process versns that of one in a controlled laboratory environment  

Possibly less obvions, bnt eqnally signihcant, is the fact that the integrity of the sample is more likely retained when it is not removed from the process which is to be characterized in contrast to the laboratory analysis this approach can offer trae process analysis versus merely sample analysis. This inherent characteristic can be a donble-edged sword, however. While the signal from a weU-designed and operated analyzer contains a variety of information that can be effectively used for process understanding and control, there are also nniqne challenges for the robust performance of a process analytical method. 

Additional advantages of process analyzers are the possibility to automate all or most parts of the analysis to offer the opportunity of a 24/7 unattended operation. On the downside, the level of complexity and upfront effort during the design, implementation and even maintenance stages can be high and require specialized expertise.
