Label	Id	Description
target capture specification	OBI_0001899	[A plan specification which specifies how the material enrichment procedure will influence the scale, or type of material that will be assayed in the specimen.]
mass selective detector	OBI_0000569	[A mass selective detector is a GC detector that uses mass spectrometry. It is based upon the ionization of solute molecules in the ion source and the separation of the ions generated on the basis of their mass/charge ratio by an analyzer unit. This may be a magnetic sector analyzer, a quadruple mass filter, or an ion trap. Ions are detected by a dynode electron multiplier.]
piston-seal	OBI_0000568	[The seal made by a piston in a diaphragm pump. The unique property of the reciprocating diaphragm pump is that the actuating piston does not come into direct contact with the mobile phase and thus, the demands on the piston-cylinder seal are not so great. The diaphragm has a relatively high surface area and thus, the movement of the diaphragm is relatively small and consequently the pump can be operated at a fairly high frequency. High frequency pumping results in a very significant reduction in pulse amplitude and, in addition, high frequency pulses are more readily damped by the column system. Nevertheless, it must be emphasized that diaphragm pumps are not pulseless.]
chromatography consumable	OBI_0000601	[A chromatography consumable is a consumable that is used in a chromatography experiment.]
Bruker UltraShield NMR magnet	OBI_0000567	[An NMR magnet manufactured by Bruker that ensures field homogeneity without amplified effects from vibrations or thermal changes. This magnet technology uses active shielding and optimizes coil design.]
electrical conductivity detector	OBI_0000565	[The electrical conductivity detector measures the conductivity of the mobile phase. There is usually background conductivity which must be backed-off by suitable electronic adjustments. If the mobile phase contains buffers, the detector gives a base signal that completely overwhelms that from any solute usually making detection impossible. Thus, the electrical conductivity detector a bulk property detector. and senses all ions whether they are from a solute or from the mobile phase. In order to prevent polarization of the sensing electrodes, AC voltages must be used and so it is the impedance not the resistance of the electrode system that is actually measured. From a physical chemistry stand point the conductivity of a solution is more important than its resistance. However, it is the resistance (impedance) of the electrode system that determines the current across it. The resistance of any conductor varies directly as its length and inversely as its cross sectional area.]
tecmag EAGLE probe	OBI_0000564	[The Eagle is a 4 mm 1H/X solid-state MAS probe with a top spinning speed of 18 kHz. Its simple design is robust, reliable and easy to spin. Configurations are available for 200 to 600 MHz wide bore magnets on Tecmag, Bruker, Chemagnetics, JEOL and Varian spectrometers.]
email address of specimen collector	OBI_0001890	[An email address of the person collecting the specimen]
fluorescene detector	OBI_0000563	[A single wavelength detector, where the excitation light wavelength is normally a mercury lamp generated high intensity UV light at 253.7 nm. Many substances that fluoresce will be excited by light of this wavelength and hence be detected.]
sequencing facility organization	OBI_0001891	[An organization that provides sequence determination service]
specification of data to be generated in an investigation	OBI_0001892	[An objective specification which indicates the type of data that will be generated and submitted to a database.]
anion trap column	OBI_0000562	[An anion trap column is a trap column and ion-exchange column which contains cationic anion-exchange resins.]
trap column	OBI_0000518	[A trap column is a chromatography column which is used prior to a, e.g. mass spectrometry, separation to clean up or concentrate controlled amounts of samples prior to elution to a detector.]
soil	ENVO_00001998	[Soil is an environmental material which is primarily composed of minerals, varying proportions of sand, silt, and clay, organic material such as humus, gases, liquids, and a broad range of resident micro- and macroorganisms.]
transfer line	OBI_0000572	[A combination of devices that are used in connection with a sampling head for transferring components of an applied sample to the analyzing part of a chromatography system.]
manufacturer role	OBI_0000571	[Manufacturer role is a role which inheres in a person or organization and which is realized by a manufacturing process.]
spin column	OBI_0000570	[A spin column is a chromatography column which is suitable for putting it into a centrifuge. A spin column enforces separation through increased G-forces while spinning the column in a centrifuge. It is often used in DNA gel extraction kits.]
Varian UNITY spectrometer	OBI_0000579	[The predecessor series of the Varian UNITY INOVA spectrometer.]
NMR sample tube	OBI_0000578	[The sample-tube holds the NMR sample and sits in the nmr probe. It is usually a glass tube of 5-20mm diameter.]
test tube	OBI_0000836	[A test tube is a device consisting of a glass or plastic tubing, open at the top, usually with a rounded U-shaped bottom which has the function to contain material]
