In today's fast-paced world, time is of the essence. Analytical instruments must be able to process samples quickly and efficiently, allowing researchers and industrial professionals to make timely decisions. High-throughput instruments, such as automated liquid handlers and robotic systems, have become increasingly popular, as they can process multiple samples simultaneously, significantly reducing the time required for analysis.

3. Sensitivity and Detection Limits

The sensitivity of an analytical instrument refers to its ability to detect and quantify trace amounts of analytes. In many cases, researchers need to identify and measure substances present in extremely low concentrations. High-sensitivity instruments, such as inductively coupled plasma-mass spectrometry (ICP-MS) and gas chromatography-mass spectrometry (GC-MS), are essential for such applications. The detection limits of these instruments must be low enough to ensure reliable results.

4. Versatility and Compatibility

Analytical instruments should be versatile, capable of handling a wide range of sample types and matrices. This versatility is particularly important in industries such as pharmaceuticals, environmental monitoring, and food safety, where samples can vary significantly. Compatibility with various analytical techniques and accessories is also crucial, as it allows users to expand their analytical capabilities and adapt to changing requirements.
