Eluent Degassing Device : DEGASSER ERC-3115alpha, 3215alpha, 3315alpha,
3415alpha
The new ERC-3000alpha series degasser for HPLC is a very compact high quality
unit that comes with all of the safety features that chromatographers expect from
the world's premiere manufacturer of eluent degassers. This newest, most advanced series of degassers removes the dissolved gas in HPLC eluents easily and efficiently.
Simply connect the unit in front of the pump to obtain stable chromatograms and reliable pump operation.
(Features)
* Small internal volume: solvent replacement is easy and quick. High performance: degassing performance is unsurpassed despite the small internal volume.
* Unique safety features: internal pressure and leak monitors work to prevent damage in unusual situations.
* Use with any HPLC pump; can even be used with quick-return type pumps due to low internal flow resistance.
* High quality: ERC degassers are designed, manufactured and tested in an ISO 9001 certified facility. All units also conform to CE safety specifications (EMC and LVD).
* Non-metallic solvent contact pans. |
(Principle)
As the eluent flows through the degassing tube made of special macromolecular film, the dissolved gas will be removed through the tube wall when the ambient pressure is reduced. This pressure reduction is controlled by the built-in pressure sensor, controller and membrane vacuum pump.
