Products/Services for helium mass
Spectrometers are analytical instruments which disperse an emission (such as particles or radiation) according to some property of the emission (such as mass or energy) in order to measure the amount of the dispersion. This product area includes Portable / Miniature, visible, infrared (IR), ultraviolet (UV), atomic absorption (AA), optical emission (OE), Raman, X-ray fluorescence (XRF) and mass spectrometers. Specific search forms are also available. Search by Specification | Learn More about Spectrometers
Mass spectrometers separate ions by their mass-to-charge (m/z) ratios. They are used to identify compounds by the mass of one or more elements in the compound. They are also used to determine the isotopic composition of one or more elements in a compound. Search by Specification | Learn More about Mass Spectrometers

Mass finishing equipment uses loose abrasives or tumbling media combined with cleaning or polishing compounds to bulk-finish parts. Search by Specification | Learn More about Mass Finishing Equipment and Tumblers
Helium neon (HeNe) lasers have an emission that is determined by neon atoms by virtue of a resonant transfer of excitation of helium. They operate continuously in the red, infrared and far-infrared regions and emit highly monochromatic radiation Search by Specification | Learn More about Helium Neon Lasers
A mass flow meter is a device that consist of a mass flow sensor or transducer and signal processing electronics. Fluid (liquid or gas) flow is measured in mass rate units (lbs/min). Search by Specification | Learn More about Mass Flow Meters and Controllers
Mass liquid flow switches and mass gas flow switches are devices used for measuring the flow or quantity of a moving liquid or gas in terms of a unit of mass per unit time, such as pounds per minute. These devices may be sensors with electrical Search by Specification | Learn More about Mass Flow Switches
Helium cadmium (HeCd) lasers are relatively economical, continuous-wave sources for violet (442 nm) and ultraviolet (325 nm) output. They are used for 3-D stereolithography applications, as well as for exposing holographs. Search by Specification | Learn More about Helium Cadmium (HeCd) Lasers
