The liquid chromatography autosampler is designed for use with the SP8000 high-pressure liquid chromatograph. The autosampler is microprocessor controlled by the SP8000. It holds up to 210 samples in multiple test tube racks. Each tube may be covered by a thin plastic cap to prevent evaporation and release of toxic vapors. A sipper needle pierces the cap as each tube is brought to the sampling position, and a peristaltic pump transports the sample to the injector loop of the chromatograph. Spectra-Physics 404

Model 572 single-NIM-width nuclear spectroscopy amplifier features a builtin pulse-pileup rejector and gated baseline restorer that includes automatic threshold control. The pulse-pileup rejector significantly reduces background throughout the selected energy range and minimizes spectrum distortion at high count rates. Newly developed active filter pulse-shaping networks result in symmetrical outputs over a wide range of time constants. Excellent dc stability eliminates spectrum broadening caused by dc drift, and enables the user to get the best possible performance out of any modern detector. EG&G Ortec 419
