Transitioning To Hydrogen As A Carrier Gas For Gas Chromatography In Place Of Helium
Gas chromatography (GC) employs a variety of gases as a mobile phase, but helium has long been the preferred choice due to its inertness, safety, purity, and superior performance. However, despite its benefits, using helium as a carrier gas for GC analysis poses difficulties such as persistent supply chain problems and higher costs than alternatives like hydrogen.

Considerations For Custom Seal Design
Seals are integral to hydraulics and pneumatics systems in industrial and consumer applications. A stamp can be defined as “a mechanical device which prevents fluid leakage from one part to another, the most common being an O-ring, but also including ball or piston ones. A custom gasket design requires some key considerations when deciding on the type of high vac depot best suited for a specific application. A proper gasket design must be employed to minimize the risk of any...

Detection, Quantification and Mitigation of Pump Oil Vapors in Vacuum Systems
Systems evacuated with oil-based pumps may be affected by backstreaming of pump oil vapors into the fore- line, vacuum chamber, and upstream throughout the system. The act of pump oil vapors moving against the flow of molecules traveling from the vacuum chamber to the pump(s) is referred to as the back- streaming.

Best and Worst Materials for Vacuum Service
Choosing the best material for your vacuum system is an important decision. Not only does it affect the cost of the machine, but also its efficiency, durability, and capacity. Though not all materials are suitable for every system, some standouts can save you money in the long run. Here’s a list of what to watch out for.

How To Inspect A Seal Surface
Seals are used in a variety of machines. Their purpose is to guard against any kind of leak from gas, water, or air. The main idea in using them is to greatly reduce the loss of any substance in a machine or an engine. Some of the most common uses for sealants are in vacuum systems. They are complex setups that are mainly used in major industries. Oil is transported through the tank right from the source. Good vacuum systems...

Why Using Bellows Matters
Bellows are versatile and easy-to-use devices that have many applications. One common feature is that they use a flexible tube to expand and contract, which can control the flow of air or liquid through a system. Also, they are typically used in applications where it’s essential to control the amount of gas or liquid moving around, such as medical devices and aerospace equipment. In the world of vacuums, they are an accessory that works as a tool and matter to...

Bellows: Hydro-Formed vs. Edge-Welded
Metal bellows have been in use for centuries. Over the years, they have been major components in sealing applications and demanding sensing for industries. They are the perfect solution for dealing with pressure or installation issues. Bellows can convert the changes in their internal and external pressures. They can deflect elastically to respond and contain the force applied to them and, in turn, exert a reactive force. Metal bellows come in two types; hydro-formed and edge-welded. This article will delve...

O-Ring Seals And Design Considerations
An O-ring is a tubular piece of material, either an elastomer or metal, with a cross-section in the shape of a circle that can be compressed to fit tightly into a circular grove and seal against the sides of the track. An O-ring, also known as a packing, is a flexible gasket in the shape of a loop — it is a elastomer with a round cross-section designed to be seated in a groove and compressed during assembly between two...
