The GC1000 Mark n offers two new process gas chromatographs: the Isothermal Oven type which sets new standards for easy operation and reliable performance; and the Programmed-Temperature Oven type which has the same easy operation plus features optimized for capillary column applications. The clear path to operational excellence

Our Advanced New Process Gas Chromatograph Gives you All You Expected ... And Even More Vast Experience and Original Technology It is now more than 30 years since Yokogawa shipped its first process gas chromatograph. During those three decades, we've put more than 6,000 units into operation. As Japan's leading manufacturer of process gas chromatographs, Yokogawa has always offered its customers the most advanced gas chromatograph technology available. New Gas Chromatograph Responds to Today's Needs With today's relentless emphasis on cost reduction, managers are demanding ever-tighter quality...

Dramatically Improved Ease of Use Operating Display Electronic Circuits All operations are easily accessed using the operating display panel keys. Analyzer information is displayed in simple English on the LCD display. You can easily call up all the information you need ... operating status, alarm displays, analysis results, temperature status, chromatograms, and operating parameters ... just by pressing single keys. The electronic circuits are mounted inside a pressurized enclosure. This microprocessor-based unit provides signal amplification, waveform processing, sequencing, PID temperature...

Newly Developed Hardware at the Heart of the Analyzer Significantly Enhances Analysis Reliability New Isothermal and Programmed-Temperature Ovens Achieve Outstanding Temperature Stability and Repeatability Highly stable temperature control in the isothermal or programmed-temperature oven is critical for stable gas c h r o m a t o g r a p h m e a s u r e m e n t p e r fo r m a n c e . Temperature control accuracy, temperature program repeatability, and heating rate in par ticular are fundamental to perfor mance, and the GC1000 instruments achieve outstanding characteristics in these areas thanks...

Capillary Columns Capillary columns offer separation capability an order of magnitude faster than packed columns. Thus they are highly attractive for analysis of high boiling point or adsorptive samples. Since The GC1000 features hardware that enable laboratory GC analysis conditions to be employed without compromise in process applications, you can take full advantage of the high separation capability of these capillary columns. Highly Reliable, Field-Proven Stream Switching Valves These stream switching valves are the fruit of Yokogawa's more than 30 years of process gas chromatograph experience...

Easy Operation Via User Friendly Displays Main Features ● Direct display of analytical data: Display operating status information, chromatograms, and other data with one touch via dedicated keys. ● Selectable operating modes: The following operating modes are available for selection according to the user's needs. ● Column end-of-life warning function: A column end-of-life warning can be obtained by setting numeric criteria for column retention time, separation, and tailing factor according to the application. ● Process mode: Normal process measurement mode. ● Lab mode: Similar functions to lab...

Analysis Results P.Time Dett Displays data such as concentration and retention time for each peak in most recent analysis. Display of analysis results in chromatogram form. Display of analysis results in chromatogram form with expanded time axis. (Example 2) Active Alarms Displays alarms generated during analysis, with time of occurrence and description of type.

Capability That Proves Worth in New Applications Naphtha Analysis Programmed-temperature operation dramatically shortens analysis time for wide boiling range liquids such as naphtha with no sacrifice in resolution. Gasoline Analysis With features such as programmed-temperature oven, liquid sampling valve with vaporizer, and capillary columns, gasoline analysis is now possible. Simulated Distillation Analysis Distillation analysis is a tool used to ensure the quality of hydrocarbon mixtures. With it's highly repeatable programtemperature oven and welldesigned liquid sample valve, the GC1000 has...
