And nothing produces these benefits like the Agilent 6890N Network GC. By integrating leading-edge technologies with an emphasis on quality manufacturing processes, the 6890N will bring a work ethic to your laboratory that’s matched only by your own.6890N N e t w o r k G C :I t w o r k s a s h a r d a s y o u d o .* Available through Agilent Channel Partners.6890N Network GC: It works as hard as you do. 3More Productive than Any Other ECDThe Agilent 6890N micro-electron capture detector gives you greater throughput, less rework, reduced susceptibility to contamination, and expanded detection limits compared with any other electron capture detector. This detector offers the best sensitivity and linearity in the world. You do not have to concentrate extremely dilute samples and you do not have to dilute concentrated samples to get within the sample calibration range. Furthermore, this rugged, completely redesigned detector,which is optimized for capillary chromatography, lets you perform fast GC.Decreased Calibration TimeYou can manually enter existing calibration data and make a run with just one standard peak.The system can normalize the calibration table for you, allowing you to cutcalibration time and avoid re-running your calibration standards.Increased Laboratory EfficiencyClock-time programming allows you to set up runs for unattended operation whenever you want. The system can be ready to work when you get to your laboratory.Pre-run and post-run commands automatically prepare the system for the next sample.An instrument that understandsan honest day’s work.From operator interaction and sample input to separation, data acquisition, and analysis, the Agilent 6890N network GC system is Micro-Electron Capture Detector6890N N e t w o r k G C :I t w o r k s a s h a r d a s y o u d o .4High Sample ThroughputThe 6890N network GC system is already set up for the Agilent 7683 automatic liquid sampler,enabling fast and easy installation.Single or dual injectors, equipped with either an 8-sample turret or a 100-vial sample tray, allow unattended operation. Using the 11-vial transfer turret with the tray and the solvent saving mode,you have enough solvent to run unattended eight times longer than before.100-vial sample tray8-sample turret for use without trayEfficient Data HandlingThe Agilent ChemStation for the 6890N network GC system lets you display, calibrate, and report data from up to four signals—without having to synchronize separate runs and merge results.This isparticularly efficient when you need to set up and report complex analyses.Agilent’s Cerity Networked Data System for Chemical QA/QC givesyou exactly what you need for your particular laboratory environment. Use-specific applications model your everyday tasks,making every step more efficient. Cerity NDS also connects you with your company’s intranet and the Internet for pulling in what you need to work efficiently or sending out results to your customers, fast.Automatic Liquid Sampler6890N Network GC:It works as hard as you do.511-vial transfer turret for use with trayMinimal ReworkThe Agilent 6890N network GC system is the only GC system that automatically selects the optimum pressure-control mode for split and splitless analyses. Forward-pressure control is best for splitless injections. Along with a large inlet liner volume and pressure-pulse operation,this mode reduces discrimination, sample degradation, and sample loss caused by liner overload while maximizing sensitivity.For split injections, the system automatically selects back-pressure control for linear split ratios over the entire usable split-ratio range and over wide column flow and pressure ranges. This reduces sample preparation and increases reproducibility and accuracy.Automatic switching between forward-and back-pressure modes yields optimal results in less time and with less effort.6890N N e t w o r k G C :I t w o r k s a s h a r d a s y o u d o .6The Agilent 6890N works as hard to meet regulatory requirements as it does to meet the needs of your lab. That’s why Agilent designed into the GC ChemStation a variety of features to answer the strict regulatory, certification, and quality control requirements of your industry. Agilent’s expert staff of engineers will work for you too— our installation qualification and operational qualification/performance verification services can help ensure your lab is in complete compliance.A Record of All EventsBoth the Agilent Cerity Networked Data System and Agilent ChemStation Plus family ease the burden of meeting regulatory and quality requirements.Both software programs, for example,record all system events during an analysis. This includes any anomalies or deviations from method setpoints.System Performance ControlA system suitability table lets you easily set range limits on critical parameters toestablish and verify system performance.Results that meet regulations—and your expectations.Good Laboratory PracticeAssured Method SecurityYour original method, including all GC parameters and data files, can be stored in a single protected,uneditable format for assured integrity. Furthermore,your methods and data are protected by a keyboard lock and multilevel security.6890N Network GC:It works as hard as you do.7You want to keep your cost-per-analysis down— but not at the cost of unreliable results. That’s why Agilent designed the 6890N to do much of the work for you. It’s easy to operate, with minimal time required for training, prep and data handling.You’ll save time by entering all GC parameters electronically. Once set, they remain precisely the same for accurate and reproducible results you can count on, every time, with every operator, and with minimal rework.Unsurpassed Reproducibility Full electronic pneumatics control (EPC) makes it fast and easy to set all pressures and flows.Our fourth-generation EPC keeps these setpoints constant from run to run,providing excellent retention time reproducibility.Simplified ControlThe 6890N keyboard simplifies parameter entry and system control.The keyboard displays four parameters of your choice,giving you instant access to system information— for fast,effective diagnostics and troubleshooting.

At the same time, you get the convenience of automated injection. Other benefits include improvedprecision and accuracy (with the industry’s fastest injection speed) and the ability to sample individual layers in a vial for automated micro-liquid/liquid extraction and ambientheadspace analysis.No Sample ConcentrationThe system’s automatic liquid sampler offers large-volume injection, eliminating sampleconcentration steps. Using the programmable temperature vaporizing inlet or cool on-column inlet, you can inject up to 50 µL in a single injection.If you are using a programmable temperature vaporizing inlet, you can inject up to 500 µL, with multiple injections. This gives you highly sensitive quantitation—especially useful for mass selectivedetection and atomic emission detection.With enhanced technologies, the 6890N works harder than ever to increase your lab’s performance. Both injection and headspace sampling are automated, which means less manual work and even more precise results. You’ll enjoy quicker turnaround time, lower cost per analysis, and less waste.Small-Volume SamplingMultiphase Sampling Ambient HeadspaceSamplingT ake the work outof manual sample prep.Large-Volume Injection10No Sample PreparationHeadspace sampling can eliminate sample preparation byintroducing volatile components automatically—from virtually any matrix—directly into the GC. A low-volume, highly inert volatiles interface is optimized for headspace-GC analysis, preventingsample loss or degradation. Agilent headspace instrument control is fully integrated into the Agilent GC ChemStation software.Reduced DerivatizationA cool on-column inlet offers a gentle environment for thermally labile compounds.
