The Lab-on-Valve is a compact sequential injection analyzer for all-in-one chemical analyses. The FIA-SIA-LOV Sequential Injection Analyzer combines a computer-controlled six-position valve, precision syringe pump, and spectrophotometric flow cell in a 12.7 x 15.3 x 15.3-cm package that can automate virtually any wet-chemistry lab procedure. Software-control procedures with simple commands sequence through sample dilution, addition of reagents, and mixing and routing of the sample through the flow cell for continuous or stopped-flow measurements.
    The FIA-SIA-LOV Sequential Injection Analyzer features FIAlab Instruments’s Lab-on-Valve technology —a fully integrated, six-position selector valve that enables flow injection, sequential injection, and bead trapping with a single component. Because all the chemistry takes place within the valve manifold, the need for additional tubing and connectors is eliminated. The injection analyzer also offers cost-effective, microliter methodology; it produces less waste, saves money, and introduces fewer chemicals into the environment. The unit weighs just 3.6 kg, making it both portable and easy to install in small incubators for temperature and humidity control. It can be positioned near ETAAS and MS systems so that microvolumes of processed samples need not be transported through long conduits, which can cause degradation.
    The analyzer is used for applications such as analysis of dissolved constituents in water, biological samples, and process streams, as well as more complex procedures that require separations, such as immunoassays. Nearly any standard colorimetric flow injection analysis method can be adapted to SIA and performed on the unit with few or no modifications to the manifold. It also offers multichannel, multiassay flexibility: up to 12 interconnected FIA-SIA-LOV systems, all controlled by a single computer and operated in a multichannel format. If needed, the components can be separated and run individually.
