We're not known as The Chromatography People·
Just give us time. Look us over carefully. We know we've got one of the most complete lines going. Proven systems. Ours and those we recently acquired from Barber-Colman. We think it's one of the best lines available. Now, think of your samples. These days they can be almost anything. Bourbon. Lemon oil. Isobutane. Moon dust. Vanillin. Engine exhaust. Salmon eggs. Proteins. River water. Cholestérols. Crude oil. Barbiturates. City air. Waxes. Whatever you're analyzing, our systems will give you clearer answers in less time and at less cost. We're modular. Solid state. Computer compatible. Plain or radioactive. We're simple. Sophisticated. Or supersophisticated. Take your pick. Like we said. Look us over. We're all yours.

Chromatograph. Utilizes "Hot Pop" cap sules or metal gauzes for sample intro duction. Permits 24-hour unattended operation for either isothermal or temper ature programmed analyses. Handles up to 72 stored solid samples (and up to 35 liquid samples). Circle No. I l l on Readers' Service Card. Series 5 0 0 0 GC Systems. Our completely modular approach offers you the precise system you need now and the freedom to add any accessory option later — easily and at minimum expense. Current Series 5000 accessory systems include Radioactivity Monitoring (RAM), Cryogenic Programming, Pyrolysis, Auto matic Temperature Programming and Cool-Down, and Automatic Sample Injec tion (see below). Our modularity also means great versatil ity. You can choose from several different detectors (all with unexcelled sensitivity), three kinds of columns (analytical, prep and capillary), dual detection systems, and multiple inlet systems. Low-noise signals and reproducibility are vital to computer operation. The Series 5000 solid-state electrometer and highly efficient detection systems provide free dom from noise, drift and environmental conditions. Our electronic programmer and cool-down controller, plus insulated flow controllers, assure excellent chro matographic reproducibility. SERIES 5 0 0 0

PESTICIDE
ANALYZER.
A specialized GC unit for the analysis of pesticide residues at the ppb level. Circle No. 115 on Readers' Service Card. Model 4 9 9 8 for Gas Radiochromatography. (Not Illustrated.)
Model 5 4 0 2 Liquid Chromatography Detection System. Utilizing a flame ionization detector and a continuous conveyor system, this detec tor continuously monitors the effluent from a liquid chromatograph. Can be used for micro, analytical and preparative columns. Extremely high sensitivity, response to all organic compounds, and removal of sol vent by evaporation permit broad appli cation. Circle No. 112 on Readers' Service Card.
Like we said — plain or radioactive. You pick it. This compact outfit operates with any gas chromatograph. Provides direct, continuous detection and measurement of radioactive components in the gaseous effluent. At column temperatures up to 300 CC. Circle No. 116 on Readers' Service Card.
Model 4995 for Paper-Strip Radiochromatography. •«ώ.\
Series 5 3 0 0 Instruments. Utilizing the same detection systems as in our Series 5000, outstanding performance is obtained at minimal cost. Three basic self-contained instruments are offered: thermal conductivity, flame ionization, and a pesticide analyzer equipped with an electron capture or phosphorous detector. MODEL 5 3 4 0 THERMAL GAS
CONDUCTIVITY
CHROMATOGRAPH.
For organic compounds and stable gases; foods, flavors, paints, and perfumes. Circle No. 113 on Readers' Service Card.
Here, it's being fast between radioactive peaks that counts. Our Actigraph® III Sys tems are just that. They speed up the strip between peaks and automatically print out peak counts. Accurate. Precise. Thinlayer-plate scanning, too. Circle No. 117 on Readers' Service Card. Model 4 5 2 6 for Aqueous-Stream Radiochromatography. (Not Illustrated.)
A complete, single-channel radiation counting system for nondestructive detec tion, analysis, and recording of radioactive components in a flowing aqueous stream. From your liquid-partition column. Con tinuously. Directly in the column effluent. Circle No. 118 on Readers' Service Card.
