For David Hemmig, director of equipment sales at Matheson Tri-Gas (Basking Ridge, NJ), the key word in on-site gas generation is reliability. He explains that a major problem with gas generators that incorporate some sort of compressor is that eventually that component fails.

Microplate handlers are the robotic “glue” that unifies operations around a microplate workflow. The
 evolution of robotics and software has caused a “democratization” of lab automation in general, and microplate handlers in particular.

Total organic carbon (TOC) analyzers present a rapid, efficient measure of the carbon contamination content of public drinking water and ultrapure water for lab operations.

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

The pros and cons of high-performance liquid chromatography (HPLC) compared with ultra-high performance LC (UHPLC) are by now the stuff of legend.

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.

Centrifuges work on the principle of sedimentation facilitated by an apparent angular force that draws components of a rotating sample away from the center of rotation. Although centrifugation theory is straightforward, its engineering literature is voluminous due to the number of industries and research operations that depend on the operation.

Users decide between dedicated and multipurpose systems

Sequestration and the macroeconomic outlook keep confidence in the doldrums

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.
