Most HPLC analyses employ some form of sample preparation, especially with low-concentration analytes in complex mixtures.

Refractometry is thought to be a limited analytical technique that works best with binary solutions—for example, salt or sugar solutions—where it excels at precise concentration measurements.

Controlling the environment and the operation determines much of the accuracy

Users decide between dedicated and multipurpose systems

Almost every piece of equipment—from a computer to an oscilloscope and beyond—uses a power supply. Scientists expect power supplies to keep going and going. Luckily, most of them do. Those power plants inside devices, though, come in a wide assortment.

Glove boxes are containment systems for protecting samples, processes, and products from operators and the environment—or the other way around

Microscopy means many things to many different laboratories. One constant remains beyond the dizzying array of choices: constant technologic improvement based on the confluence of diverse technologies.

Pipetting is part of nearly every laboratory’s workflow. Yet this established technology continues to undergo improvements, most related to usability and consistency.

For all its maturity and secure establishment in chemical analysis, predicting the future of gas chromatography is an exercise in uncertainty.

Chemical processing and analysis are fueling a resurgence of interest in highly purified specialty gases. Novel gas-phase chemical reactions reduce the number of unit operations and side products while eliminating the disposal of toxic solvents.

Across research laboratories and industrial manufacturing facilities, many processes must be kept at a specific temperature, and that requires baths and chillers.
