It’s official: Sample and standards preparation are significant bottlenecks in high-throughput laboratories, particularly those partly or fully automated. Improved instrument sensitivity—and the need for speed and accuracy—have made sample prep a top priority.
A Question and Answer with Select Automated Sample Prep Experts
Despite protestations to the contrary, automation is not something to undertake casually. Due to the dizzying array of possibilities and workflows, the technology has not yet achieved the simplicity of consumer products.
A comprehensive review of sample preparation would require a multivolume work. Beyond that, covering the possible number of workflows given the hundreds of potential “unit operations” would fill an encyclopedia, especially when solids (rock, soil, animal tissue) are considered.
Sample preparation (“prep”) is a tedious, time-consuming task but a necessary part of nearly every analytical workflow, regardless of industry or laboratory type.
Arguing against lab automation is becoming more difficult, particularly for sample prep. With reagents and solvents costing what they do, a business case based on direct cost savings for critical materials stands on its own.

Microwave digestion is the preparation method of choice for analyzing metals in complex mixtures. Food and environmental industries favor this technique, which is also applicable to testing materials, soil, agricultural waste products, engine oils,
Problem: Highly concentrated nucleic acid and protein samples must be diluted before they can be read on most absorbance-based spectrophotometers, and conversely, diluted samples must be concentrated
