Description

Features

The Global FIA miniSIA-1 represents a new generation of instrumentation for the proven Sequential Injection technique. It combines sampling frequency and speed of response of FIA with the robustness and reagent economy of SIA.  The key to this new capability is the marrying of the Global FIA milliGAT pump with flow programming. The concept was first described by Ruzicka in the FIA Tutorial

 MiniSIA-1mani

The system is equipped with a milliGAT pump coupled to a heating coil and Chem-on-Valve™ (COV) monolithic manifold.  An extra measure of modularity is built into the COV by making the detector flow cell a bolt-on piece.  This means that the same manifold can be configured with a short or long path length absorbance cell, fluorescence cell, chemiluminescence cell, and one of a host of different electrochemical detectors. External instruments such as Atomic Absorption, Inductively Coupled Plasma and Electrospray MS are compatible with miniSIA-1 since the milliGAT pump provides a wide range (6nL/sec to 170 µL/sec) of highly reproducible flow rates over long periods of time.

For spectrophotometry the standard 10 mm uv/vis absorbance cell uses fiber optic (f.o.) cables to pipe light to and from the flow cell. A white LED and a WXe lamp are provided as light sources.  The spectrometer is an Ocean Optics USB-4000. 

The sample port has an inlet and outlet which meet on the face of the COV rotor.  Thus the sample can be primed to the valve without drawing sample into the rest of the manifold where it can be a source of carryover.  The sample port can also be primed with the next sample while the present measurement is underway, either manually or by a miniaturized metering pump.
