There are no restrictions when choosing mobile phase conditions, no worrying about competing ions or pH. Selection and adjustment of conditions can be made on a sample or analyte basis. The high degree of versatility of this non-suppressed system allows the analysis of various ions without peak broadening outside the column.
Every module of the Shimadzu LC-VP series has been designed to exacting standards to provide an optimum HPLC system. This makes high sensitivity analysis possible even with a non-suppressed system. As little as 1 ppb of F- can be analyzed without any preconcentration procedures.
This system permits the analysis of both cations and anions from a single sample vial, efficiently measuring the ion balance. With Shimadzu's unique high performance column, the Shim-pack IC-A3, and large volume sample injection, the quantitation of F- at levels of less than 1 ppb is possible. The simultaneous quantitation of monovalent and divalent cations at ppb levels is also possible with Shim-pack IC-C3 columns. The non-suppressed system provides a linear calibration curve even at low concentrations, as well as extremely good reproducibility of quantitation results.
The PIA-1000 consists of a solvent delivery unit, a manual sample injector, a column oven, a conductivity detector, a data processor with a floppy disk drive and a housing for elution and drain bottles in a 15kg (33lbs) light weight compact transportable body. This Analyzer has all its flow paths made of metal-free materials, and employs 2.0mm I.D. semi-micro bore column. The amount of mobile phase consumed is only about 1/5 of that used by equivalent systems employing conventional (i.e., 4.6mm I.D.) columns.
Compared with the conventional ion chromatograph systems, it can be used more easily with its touch panel display user interface.
The PIA-1000 is operated by either AC power supply or DC battery so that it can be installed anywhere as far as such power source is available. These features enables “On-site” analyses at sampling location, or installation at location with limited space.
