pies at one time with recoveries of 85100% and 2-3% coefficients of variation while reducing solvent use up to 95%. Samples are processed through dispos­ able cassettes prepacked with a variety of selective sorbents. Applied Separa­ tions 444 XRF. Fluoroderm XRF-300 features a large-capacity measuring chamber that automates calibrations, sample mea­ surements, collimators, and filters. Also included are a fully programma­ ble, motorized X-Y-Z stage, and duallayer measurement capability. Color graphics, measurement data, text, and the sample are displayed on a high-res­ olution monitor. UPA Technology 445 Pyrolysis GC. Curie Point Pyrolyser, intended for use with gas chromatographs and mass spectrometers, fea­ tures reproducible pyrolysis tempera­ ture, shock heat-up within millisec­ onds, and a wide temperature range by means of a large assortment of ferro­ magnetic filaments or tubes. The sys­ tem, which can be easily attached to any gas chromatograph, enables non­ volatile substances to be determined using gas chromatography. Fischer America 446
