Show • A high-performance liquid chromatograph (Waters Model ALC/GPC-244 HPLC) • equipped with dual detector plus dual pump and solvent programmer system for gradient elution chromatography. This instrument is useful in the analysis of liquid hydrocarbons, tars, and organics in water. • Several research-quality gas chromatographs. Three are fitted with flame photometric detectors for sulfur analysis. • A 6-cell oxygen plasma machine for low-temperature ashing of solid samples (below II0°C), to prevent the loss of such volatile elements as cadmium and zinc. i • A modern Philips X-ray diffTactometer and X-ray fluorescence unit. • A Metrohm automatic titrator with potentiometric and photometric capabilities. • A Polarographic instrument for electroanalytical work, plus research-grade pH meters. • A Leitz metallographic microscope for metallurgical examination of metals and alloys. • A Zeiss petrographic microscope for reflectance studies of coal and other materials. • An automatic surface-area analyzer. • A mercury porosimeter. • A 16-channel Coulter counter for subsieve particle analysis. • Research-grade UV, visible, and IR spectrophotometers. • A sample preparation room equipped to crush and sieve solid samples. • Balance rooms equipped with modern single-pan macro-, semimicro-, and micro-balances, in addition to several electric top-loading automatic balances. • Elemental analyzers for the determination of carbon, hydrogen, nitrogen, and sulfur content of solid and liquid hydrocarbon samples. • Three spectrophotometers for UV and visible routine colorimetric methods. • Automatic distillation equipment for high-efficiency distillation work, made by Podbielniak (Model 8800). • Miscellaneous furnaces, ovens, and constant temperature baths. • An automatic calorimeter for determining the heating value of solid and liquid fuels. • Various apparatus for ASTM testing of petroleum products. 7 I N S T I T U T E OF GAS T E C H N O L O GY |
