The workstation includes a Cartesian robot for solvent delivery and reagent/sample handling, a 60-vessel reaction block, a UV–Vis absorption spectrometer, and vial racks for compound storage. This article describes the following hardware additions that increase the scope and versatility of the workstation: (a) an analytical high performance liquid chromatography (HPLC) instrument and accompanying hardware interface (slide rail, autosampler); (b) three reactor blocks of 20 vessels each, with independent temperature control of each reactor block between ca. 0 and 80°C; (c) a shaker rack for mixing, dilution, or extraction of samples; (d) a rotary valve on the dispense line for complete isolation of 4 independent solvent lines; (e) sample workup features using disposable cartridges or filters; (f) provisions for dispensing inert gas, for example, for flushing through reactors or for storing solvents and performing transfer/dispense operations under. Using the new features, we are able to obtain useful analytical data from a wider range of reaction mixtures, perform parallel reactions at different temperatures, and handle solvents and sensitive reagents. © 1999 John Wiley & Sons, Inc.

The flow system comprised loop-based injection or a timed valve that introduced a variable sample volume into a spray chamber through a standard Meinhard nebulizer of an ICP–MS. Routinely analyzed samples such as water, plant, and steel were selected. The accuracy of multielement determination was checked against water standard reference material from the National Institute of Standards and Technology (1643d), plant standard reference material from the National Bureau of Standards (1572 citrus leaves), and steel standard reference material from the National Bureau of Standards (AISI 4340). The measuring system was calibrated with a multielement solution, yielding a linear plot with good precision [relative standard deviation (RSD) < 3%, n = 12]. The results were in agreement at a 95% confidence level with the certified values for the reference materials and also with those obtained by continuous aspiration and by (FI) with a discrete volume. © 1999 John Wiley & Sons, Inc.

System design is based on the division of the software into four layers, defining a communications interface among them. The definition of these layers allows the isolation of the highest, corresponding to the analytical application, from the lowest, the hardware, composed of the various parts of the block diagram.Although this system was initially designed for automating flow techniques (flow-injection analysis, FIA, and sequential-injection analysis, SIA), its conception allows the development of much more general applications, depending on the user's imagination.The system is very open, in the sense that it is not necessary to adapt the program as system possibilities are expanded. Thus, if new instrumentation (modules in the block diagram) is incorporated, one need only develop independently a minimum of software to comply with the previously defined interface.This system has been developed under the 32-bit Windows 95 environment, making the exchange of information with other applications very simple and allowing the various possibilities offered by the program to be executed simultaneously (for example, data acquisition and processing). © 1999 John Wiley & Sons, Inc.
