refimprove date April 2010 The helium dilution technique is the way of measuring the functional residual capacity of the lung s the volume left in the lung s after normal expiration . This technique is a closed circuit system where a spirometer is filled with a mixture of helium He and oxygen. The amount of He in the spirometer is known at the beginning of the test Concentration Volume Amount . The patient is then asked to breathe normal breaths in the mixture starting from FRC Functional Residual Capacity , which is the gas volume in the lung after a normal breath. The spirometer measures helium concentration. The helium spreads into the lungs of the patient,and settles at a new concentration C2 . Because there is no leak of substances in the system, the amount of helium remains constant during the test, and the FRC is calculated by using the following equation C1 V1 C2 V2 C1 V1 C2 V1 FRC FRC C1xV1 C2 V1 V2 Total gas volume FRC volume of spirometer . V1 Volume of gas in spirometer. C1 Initial known Helium Concentration. C2 Final Helium concentration Measured by the spirometer . Note To measure FRC we connect the patient to the spirometer directly after a normal breath when the lung volume equals FRC , if the patient is initially connected to the spirometer at a different lung volume like TLC or RV the measured volume will be the initial volume we started from and not FRC. In patients with obstructive pulmonary diseases the measurements of the helium dilution technique are not reliable because of incomplete equilibration of the helium in all areas of the lungs.

Unreferenced stub auto yes date December 2009 Context date September 2008 A helium ionization detector HID is a type of detector used in gas chromatograph y. Principle An HID is an GC ion detector ion detector which uses a radioactive source to produce ion s. The radioactive source ionizes helium atoms by bombarding them with emissions. As components elute from the gas chromatograph GC s column they are mixed with the helium ions, which then ionize the components. The ion s produce an electric current , which is the signal information theory signal output of the detector. The greater the concentration of the component, the more ions are produced, and the greater the current. Application HIDs are sensitive to a broad range of components. They must use helium as a carrier gas. HIDs are non destructive detectors. They do not destroy consume the components they detect. Therefore they can be used before other detectors in multiple detector configurations. The drawback to HIDs are that they contain a radioactive source. In the U.S. , this means they fall under a number of federal regulations concerning their use in the workplace, shipping, disposal, etc. Discharge ionization detector s have generally supplanted them.

A Scanning Helium Ion Microscope SHIM, HeIM or HIM is a new imaging technology based on a scanning helium ion beam. ref http nanotechwire.com news.asp?nid 2120 NanoTechWire.com Press Release ALIS Corporation Announces Breakthrough in Helium Ion Technology for Next Generation Atomic Level Microscope , December 7th, 2005 retrieved on November 22nd, 2008 ref This technology has several advantages over the traditional scanning electron microscope SEM . Due to the very high source brightness, and the short De Broglie wavelength of the helium ions, which is inversely proportional to their momentum, it is possible to obtain qualitative data not achievable with conventional microscopes which use photons or electrons as the emitting source. As the helium ion beam interacts with the sample, it does not suffer from a large excitation volume, and hence provides sharp images on a wide range of materials. Compared to a SEM, the secondary electron yield is quite high, allowing for imaging with currents as low as 1 femtoamp . The detectors provide information rich images which offer topographic, material, crystallographic, and electrical properties of the sample. In contrast to other ion beams, there is no discernible sample damage due to relatively light mass of the helium ion. Since 2007 this technology is commercialized and instruments have been shipped to customers. ref http www.smt.zeiss.com C1256A770030BCE0 WebViewTopNewsAllE 573B9EA1B720BBBEC12573080048AF79 Carl Zeiss SMT Press Release Carl Zeiss SMT Ships World s First ORION Helium Ion Microscope to U.S. National Institute of Standards ...

History of HeNe laser development The first HeNe laser emitted at 1.15 m in the infrared and was the first gas laser. However a laser that operated at visible wavelengths was much more in demand, and a number of other neon transitions were investigated to identify ones in which a population inversion can be achieved. The 633 nm line was found to have the highest gain in the visible spectrum, making this the wavelength of choice for most HeNe lasers.
