FloZF is a device control, data acquisition, and data processing package designed for the development and operation of fluidic systems such as chemical analyzers. In particular it is well suited to exploring the power of Zone Fluidics. In FloZF, the user builds and manages Projects which consist of hardware Device configuration information, the Sequences to control the devices, and data acquired from any detector devices in the Project. These three primary components of the Project are managed from their respective pages in the software package.
Device configuration takes place in the Instrument Setup page (see screen shot of the Instrument Setup page). A device is added to the Project from a list of Available Device Types. The device is then configured and tested from inside its own Instrument Panel. Depending upon the device, the Instrument Panel may also provide for “manual” control and monitoring of the device.
Sequences are created, edited and executed on the Sequence Page (see screen shot of the Sequence page). There are three panels on the Sequence Page as well as several buttons. The Resource Steps panel (at the top right) contains the building blocks of Sequences: device-specific Steps, system control Steps, and data manipulation Steps. These Steps can be dragged and dropped into the Work Sequence panel (on the right) to generate method Sequences. From here, the Steps can be modified, grouped, saved, and executed. Groups of Steps can be assembled into hierarchical arrangements of Sequences which are listed in the Resource Sequences panel at the bottom left.
These Sequences are dragged to the Work Sequence panel for modification, printing, and execution.
The Data Browser page is used to examine detector data, create and modify calibration tables, and manage data folders (see screen shot of the Sequence page). Data are stored in folders and one folder is designated as the Active Data Folder. The Data Browser page is separated into two partitions. In the left partition, a Profile Summary Table provides specific data for each profile that has been acquired and stored in the Active Data Folder. When an entry in this table is selected, the data profile appears in the plot window above the table. The significant peak parameters are listed in a table above the profile window.
In the right partition of the Data Browser page is another set of tabbed pages containing various groupings of data. Calibration tables are assembled on the first tabbed page and can be filled by dragging and dropping entries from the summary table. It is possible to generate calibration tables manually from the summary table or automatically from within a Sequence. Where it is desirable to overlay peak profiles, the second tabbed page allows the generation of Overlay Plots by dragging entries from the summary table. On the third page a graphical history of any of the peak parameters can be displayed in History Plots as histograms. The final tabbed page, Data Folders, allows you to create, open, or delete data folders. The Active Data Folder is selected on this page.
A free fully functional evaluation version of FloZF is available to download. This version will allow device control of Global FIA milliGAT pumps and Valco selection valves. These two devices are the core of any Zone Fluidics implementation.
In the early days of FIA, the most fertile repository of manifold components was the Chromatographer's laboratory. Since those early days, a whole suite of custom components have been developed for those practicing flow-based analysis. These components are now available commercially as stocked items. Global FIA provides a single source for many of the components needed to equip and maintain a flow-based analysis laboratory.
The range of components offered includes:
In recent years we have added a number of sampling components as well. These include:
All of these devices are available in the Global FIA store.
