In the present case the system was aimed at performing two-component analysis, namely, at preparing the set of two-component standard solutions and using them for calibration and determination of both components in a sample. It has been proven that the FRV, if suitably configured and operated, was capable of using only two initial standards for preparation of eight two-component solutions and furthermore, of composing them in accordance with the incomplete 32 experimental plan. Owing to that, the mathematical models then formulated on the basis of measurement data could serve not only for estimation of the concentrations of both analytes in a sample, but also for evaluation and elimination of the mutual influences between them. It has been experimentally revealed that the system developed allows the calibration procedure to be performed with low consumption of time, work, and reagents, providing reliable analytical results and valuable information about interferences. © 2000 John Wiley & Sons, Inc.

The system was completely developed with conventional equipment available in analytical laboratories. The software and hardware allows for the acquisition and manipulation of analytical signals and also for the synchronization of the actuation of each component. The assembled system is composed of a mixing valve, three solenoid valves, a commercial microwave oven, a peristaltic pump, and an ultrasonic bath. Additionally, it is possible to program 60 different events that can be controlled by the operator according to the requirement of analysis. The operator only needs to inject the samples, and the other steps are carried out by the automated SIA system. This system was applied for direct determination of Fe in white wines and presented a sampling frequency of 10 h−1. The limit of detection was 0.6 mg L−1, and an addition-recovery experiment led to recoveries in the 98–101% range. © 2000 John Wiley & Sons, Inc.

The multicomponent analysis was implemented using the absorbance signals in different intervals of time in a flow injection analysis peak for each sample solution inserted into the analytical path. A partial least squares (PLS) algorithm for model construction was developed in QuickBasic 4.5 as a subrotine in order to assemble it in a data acquisition program, permitting the concentration estimation in real time. The proposed method was successfully applied to nickel and zinc determination in synthetic mixtures with analytical throughput of 43 samples per hour. The results obtained with the proposed method were compared with Inductively Coupled Plasma Atomic E Mission Spectrometry (ICP-AES) data, and the results agreed with 95% confidence level. © 2000 John Wiley & Sons, Inc.

The system automates ASTM Test Method D 5630: “Standard Test Method for Ash Content in Thermoplastics (Procedure B)” and Phillips Ryton poly(phenylene sulfide) (PPS) laboratory procedures “Determination of Ash of PPS Compounds” and “Ash Content of Polyphenylene Sulfide.” These procedures determine the ash content of the respective resins using a rapid, muffle furnace ashing technique. The robot system automates all aspects of the procedure, including taring the crucibles, inserting the samples into and retrieving the samples from the muffle furnace, weighing the crucibles, recording the weights, cooling the crucibles, calculating and reporting the results, and storing the data. Data generated on polyolefin (polyethylene and polypropylene) and Ryton poly(phenylene sulfide) samples show that the system generates data that are reproducible and equivalent to those obtained by manual application of the ASTM and Phillips procedures. The robot system has been successfully used to determine ash values ranging as low as 0.02 wt% for polyolefin resins and as high as 40+ wt% for PPS compounds. A comparison of results from the automated procedure to those obtained by the manual application of the procedure demonstrated that the robot provided equivalent values, with estimates of the precision that were at least as good as the manual procedure. Since its installation, the system has been used extensively, increasing the laboratory's testing capacity and providing labor savings of more than 0.5 human-years annually. © 2000 John Wiley & Sons, Inc.
