| abstract | PURPOSE: To enable the securing of higher sensitivity and long-term stability by using a separation film as transporting means of a mobile phase mixed with a sample to improve the concentration of the sample without providing any complicated mechanism. n CONSTITUTION: An ultrafilter with a fraction mass number of 500 as one of separation films is used as a transporting means 11 to transport a mobile phase 2 mixed with a sample to a coupling means 4 with an LC pump 3 while a pressure control valve 12 is provided to act as a pressure resistance to maintain a pressure in the transporting means 11 during the pressurization with the pump 3. As a result, as compared with the supply to the transporting means 11 of all of the mobile phase 2 transported from the pump 3, about 90% of water of the mobile phase 2 is filtered and discharged outside the transporting means 11 to improve the concentration of the sample, which allows an output from an ion detector 9 about ten times more than that would be when this separation film is not used. Thus, the concentration of the sample can be im proved about ten times as intact in a liquid phase without adding any compli cated mechanism and long-term stability can be secured sufficiency free from maintenance. n COPYRIGHT: (C)1992,JPO&Japio |
