AUTOMATIC SOLID-PHASE EXTRACTING APPARATUS WITH SOLID-PHASE EXTRACTION COLUMN REPRODUCING FUNCTION

摘要

PURPOSE: To lower the running cost, improve the reliability, and make solid- phase extraction automatic by setting reproducing process and installing an evaluation system therefor. ;CONSTITUTION: A gradient pump 1, an auto-sampler part B, and an aspirator 4 are connected to a valve 6 of a solid-phase extracting apparatus and then conditioning of a cartridge column, adsorbing an component, cleaning it, and removing water are carried out successively and a gradient pump 2, a measuring part C, a gradient pump 3, and an evaluating part D are connected to a valve 8 and desorbing and measuring the object component of the cartridge column and reproducing and evaluating the cartridge are carried out.;COPYRIGHT: (C)1995,JPO
