As FTIR instrumentation has become more compact and reliable, it has experienced a type of commoditization. That does not mean that innovation has ceased.
With an instrument focused on removing matter from a space, the vacuum-pump industry sure creates a lot of “matter,” in terms of different devices. Vacuum pumps come in so many varieties that, well, it’s a regular vacuum-pump jungle out there.
Whether its typical samples are liquids, solids, or gases, nearly every laboratory has an ultraviolet-visible spectrometer that serves as a workhorse for dozens of applications.
As a premed student at West Texas A&M University, Josie Longoria was like many citizens of her region—she wasn't aware just how much the environment, especially water, affects human health. An environmental chemistry class changed that … and her career path.
Whether to employ central washing stations or point-of-use washers located under a lab bench or in a corner is also something that has to be addressed with regards to laboratory glassware washers. The former provide an economy of scale and are popular with lab workers who, almost universally, hate to “wash the dishes.”
Gas chromatography (GC) is a common technique used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. GC is typically used for separating the different components of a mixture, improving the purity of a particular substance, or identifying a particular compound. GC is a ubiquitous technique, and the various GC instruments available are designed to achieve every requirement of the technique.
Thermal analysis is the broad category of at least 20 techniques that measure some fundamental property of matter as a result of adding heat. For example, dilatometry measures volume changes upon heating, thermomechanical analysis quantifies the change in dimension of a sample as a function of temperature, and thermo-optical analysis detects changes in optical properties on heating or cooling.
