The various advances in system designed introduced by the knowledge of the above principles, have halved the dispersion and almost doubled the analysis rate for each new generation. For example, a typical method which uses dialysis and a heated reaction stage would run at 30 samples per hour on AAI systems, 60 samples per hour on AAII and similar systems and 120 samples per hour on third generation systems such as the Technicon SMAC, Alphem RFA300 and the Bran Luebbe TRAACS 800.

More information can be found on the manufacturer s website http //www.bran-luebbe.de/en/autoanalyzer.html The price range for a basic system with a colorimeter is about 20k to 27k depending on options (e.g. PC and flame photometer) and whether educational discount applies. 

The advantage of the 8.5 ml as opposed to the 2-ml or 4-ml conical cups, is that it is easier to pour into them, several analyses are possible before they need refilling, and they are more easily washed if reuse is considered. The snag is that the 40-place 8.5-ml industrial cup sample trays are no longer made by Bran+Luebbe, but Gradko can supply them for about 112 each.

The rice taste analyzer, developed first by Satake Engineering Co., Ltd., consists of NIR instrument provided by Bran Luebbe Company. This analyzer is based on the experimental result that rice taste is fixed by the balance of moisture, protein, amylose, and fatty acid. From a practical stand point, milled rice is ground, and the ground sample is kept at a constant temperature oven for more than one hour, after which the NIR measurement is performed to determine the amount of different constituents. From these constituents, taste scores can be calculated using taste-related equation which relates the constituents to taste score. A taste score can be generated in only a few minutes by the NIR instrument. The rice taste analyzer includes the software that calculates the blending ratio to perform lowest price at the same taste, or to perform best taste at the same price.

Continuous emulsion preparation using a metering pump system has been successfully used during the last decades in the margarine industry to meet the above requirements (76, 78) and is considered to be a very flexible installation (53). Well-known suppliers of metering pump systems are Bran + Luebbe Inc. of Buffalo Grove, Illinois, and American Lewa Inc. of Holliston, Massachusetts.

Vaccari et al. also applied NIR to the control of the lactic acid fermentation process (20). To get a chemical parameter such as the concentrations of the substrate, nutrients, and biomass, an on-line NIR system has been introduced to the quantitative determination of glucose, lactic acid, and biomass in real time during fermentation. The spectrophotometer, InfraAlyzer 450 (Bran-Luebbe Co., Germany) equipped with a cuvette for liquid was used. Lactic acid and glucose concentrations in the broth were measured with HPLC as a conventional method. The cell (biomass) concentration was measured conventionally by a drying method. A set of 45 samples of broth was used as the calibration sample set to create the calibration equation. Lactobacillus easel was cultivated in a fermentor with working volume of 3 1. The calibration equations... 

NIR milk spectra were obtained from all samples by InfraAlyzer 500 spectrophotometer (Bran- -Luebbe, Norderstedt, Germany), using a transflectance measured mode with 0.2-mm path length in the spectral region from 1100 to 2500 nm with 2-nm intervals. Spectra were recorded in the linked computer as absorbance, that is, log(l/r). Before spectral analysis each sample was warmed up to 40°C in a water bath.
