Leak detector. Model 8065 leak hunter, a hand-held unit designed for detecting leaks in gas chromatographs, features trigger operation, an automatic zero function, and an integral power supply equipped with rechargeable NiCad batteries. Also included are selfdiagnostics, earphones, and a storage case. Matheson 425 AA. Model 16 atomic absorption spectrometer can determine up to 20 elements from either solid or dissolved samples while analyzing each sample completely for all desired elements before moving on to the next sample. The complete system consists of an optical module including the lamp turret, monochromator, power supplies, and microprocessor controllers, an Atomsource atomizer, and an IBM PC-compatible computer. Analyte Corp. 426 LC detector. UVIS-203 programmable LC detector features external flow cells, prealigned deuterium and tungsten lamps, and a 256K memory. Chromatograms can be played back using any absorbance or rise time, and complete UV-vis spectra can also be recorded, stored, and played back. Linear Instruments 427 Preparative LC. S T / L a b 1200XP preparative-pilot plant HPLC system features isocratic flow rates of up to 2400 mL/min, a double diaphragm pumping system, an 1800 psi pressure limit, continuous gradient formation, and a variable UV detector. An optional computer automation module provides automated sample injection, gradient formation, and fraction collection. Separations Technology 428 AA furnace. System 2000 graphite furnace for atomic absorption spectrometry uses a total pyrolytic graphite platform to reduce chemical interferences. The microprocessor-controlled system provides rapid heating rates as a function of its flexible temperature and gas control and can store complete methods for future use.
