for fast, precise quantitative and qualitative analyses of volatile materials
THE COMPLETE "CHEMICAL SPECTROGRAPH'
F
FISHER-GULF PARTITIONER * for gas-liquid partition chromatography
Industrial and Engineering Chemistry calls partition chromatography "the greatest advance in analysis of volatile petroleum constituents . . . since the adoption of spectroscopic methods."
The Fisher-Gulf Partitioner is the first complete auto matic instrument for this revolutionary new technique. In a few minutes it makes separations that take hours by fractional distillation. The Partitioner makes the fullest use of the basic ad vantages of partition chromatography: high speed . . . high resolution . . . micro samples . . . qualitative and quantitative determinations .. . innumerable applications. It adds several unique features: AUTOMATIC INTEGRATION-No areas to estimate; the Partitioner measures them accurately. CONTINUOUS SENSITIVITY CONTROL-Makes the slightest traces measurable. LINE OPERATED—A special a-c power supply maintains constant voltage, assures a flat recorder baseline which shows the slightest deflection. TEMPERATURE SELECTOR-'Dial" the working temperature directly; a thermostat maintains it.
