Furthermore, traditional research facilities are extremely expensive to commission and run, and yet for a significant proportion of their lives they are under-used or even lying vacant.

To overcome some of these inefficient practices, continuous processing methods such as flow chemistry [ 26 — 32 ] and other enabling technologies [ 16 , 33 — 35 ] are receiving increased attention. With the continuing development of digital imaging technology, computer vision techniques and laboratory automation, some of these routine tasks may be delegated to a computer. And indeed, in cases when our eyes are simply not capable of what is required, for instance, when we would like to observe the contents of a sealed reactor or events outside the visible range of the spectrum, we have no other choice but to rely on camera technology.

Associated Data

The visual data produced are rich in information and can be used to perform complex calculations to make decisions and generate commands in real time. We consider the current state of laboratory decision making to require a human as an interface for allowing a reaction to progress, by performing a workup or a purification, or designing the next experiment Fig. By applying digital cameras and related technologies, this does not always need to be the case: We have identified a number of scenarios in which cameras have been employed by synthetic chemists to aid or enable their work.

In the simplest cases, the camera provides the chemist with a view that would otherwise be inaccessible, or to make a recording of a long experiment to be played back later at a convenient time.
