Spectrometer
Spectroscopy is a major tool used in the study of the structure and properties of molecules. In the past, spectroscopists were limited to analyzing molecules in the lab. Today, advances in technology have given us the ability to analyze molecules in nearly any location. This has led to an explosio......
analytical Instruments
Performance Analysis of Spectrometric Instruments Spectrometry is an analytical technique that examines the composition of a substance by measuring the light energy of a unique spectrum produced for it. Spectrometric instruments vary widely in their design, capabilities and price range. In this ar......

Molecular sieve adsorption pump
Molecular Sieve Adsorption Pump A molecular sieve adsorption pump is an adsorption pump or vacuum pump that works by causing molecules of a specific size or smaller to be adsorbed onto the surface of a material, typically a silica, or zeolite, called a sieve. These molecules are then trapped by t......
NMR spectrometer
Nuclear Magnetic Resonance Spectroscopy (NMR), sometimes referred to as Magnetic Resonance Imaging (MRI), is a technique used to investigate the structure and dynamics of molecules. NMR spectroscopy is a powerful tool in studying proteins and other molecules, and it has become essential in the und......

air bearing
Air bearing An air bearing (also known as an aerostatic bearing or a pneumatic bearing) is a bearing in which a forces between two surfaces are supported by air pressure. In other words, it is a surface effect bearing. The air bearing provides a smooth, low friction and consistent movement on the......

Summary of Check Valve Standards (2)
The Gate, Globe and Check Valves Standards Gate valves are primarily used to start or stop a flow in a pipe. They are often used in steam and water systems, where the flow can be intermittent or constant. Gate valves are most often used for regulate and regulate the flow of water, steam, or other......
