Developing novel pollution sensing technologies using precise mass flow control The growth of the IoT (Internet of Things) is driving the need for smaller and more ubiquitous sensors. Normally, one thinks of optical or electrical sensors in this context. This type of measurement has typically been in the province of automotive and process control industries […]
High flow control for gasification Alyssa Jenkins and Mic Chaudoir, Ph.D. Gasification is a process in which biomass or fossil fuel is converted into carbon monoxide, hydrogen, and carbon dioxide (syngas or synthetic gas).1 According to Carnot’s theorem of thermodynamic efficiency, the syngas produced is more energy rich than organic fuel in its combustion due […]
Lowering cost and increasing speed of biologics production With protocols for bioprocessing firmly established, there is an increasing focus on reducing the cost of producing biologics, biosimilars, mABs, and other modern medicines requiring bioreactions. Producing these pharmaceuticals promises to revolutionize treatment of many difficult diseases, especially modern scourges that have been resistant to small molecule-based […]
Maintaining accurate response control over the air flow is essential to paint job quality thereby reducing costs on every part painted.
Mixing gases with versatile flow control Many applications require the use of custom gas mixtures. Pre-mixed gases are often purchased from compressed gas suppliers, however it is also a viable solution to purchase pure gases and blend them yourself. Whether buying gases pre-mixed or mixing your own gas, there are several challenges to overcome. Here […]
Verifying and optimizing gas chromatography processes Gas chromatography (GC) is an important analytical technique used to separate and analyze chemical components in a mixture. Here, we provide a brief introduction to GC and discuss some of the common application challenges and mass flow/pressure solutions. How does gas chromatography work? The sample is first injected into […]
Let’s take a look at how optical fibers are manufactured, and where Alicat mass flow controllers and meters fit into the picture.
Upgrading reactive sputtering systems with closed loop flow control Reactive sputtering, a physical vapor deposition (PVD) technique, is used to coat surfaces in a variety of manufacturing processes. Common examples include: Flat-panel displays for televisions and cell phones Photovoltaic coatings on solar cells Optical coatings on sunglasses Decorative coatings on hardware and automotive components Insulating […]
Measuring flow below atmospheric pressure Measuring flow below atmospheric pressure can be challenging due to changing volumetric flow rates and pressure drop requirements. It is critical to consider operating conditions and device capabilities to ensure your flow meter gives correct readings. In this article, we will discuss the relationship between line pressure, flow rate, and […]
