Operation male easy from start to Finish !
Capillary column installation is a breeze in our spacious oven with our pre-formed graphite ferrules, large nuts, and unique capillary column holder.
Parameter setup is straightforward and precise as all critical parameters may be Set directly from the keyboard. This includes all temperatures (8 control zones) and carrier gas flow rate or pressure, column linear velocity, column flow or split ratio.
Once entered parameters are stored in 10 battery backed up files. Each file may be thought of as a GC method which may be recalled using the FILE key.
Parameters include up to a 5 ramp temperature program and a 5 ramp column inlet pressure or flow program including the time program control of Split ratio.
The FID flame is ignited from the keyboard with our new auto-ignitor.
Data collection can immediately ensue with a minimum of settings, especially if the new Wide Range F1D and C-R7Aplus Chromatopac are used,
The advanced features of the GC-17A provide a high degree of quantitative and qualitative reliability. AFC provides duplication of carrier gas flow and/or pressure unachievable in the past. This means there is better reproducibility from run to run, method to method, and instrument to instrument.
Why Develop AFC ?
Manual determination and setting of carrier gas flow parameters including split ratio is one of the most tedious and error prone steps in setting up a gas chromatographic analysis. The GC-1 7A makes flow or pressure setting simple with our new AFC system. Flow rate, column inlet head pressure, linear velocity and split ratios can be set through direct entry via the keyboard. This eliminates measuring or setting errors. Flow settings and split ratios can be precisely reproduced providing excellent quantitative and qualitative reliability.
Simple Entry/Flexible Feedback
Entry of parameters is accomplished through the keyboard and a two-line LCD display, Three parameters are typically displayed at one time as shown above for temperatures and to the right for AFC parameters. This facilitates parameter entry and minimizes key strokes.
Superior Reproducibility
One of the major benefits of AFC is that digital electronic flow or pressure setting is inherently reproducible. The data to the left illustrates the typical retention time reproducibility of constant-pressure, isothermal runs an the GC-17A. Better reproducibility means better data and increases confidence in identification and quantitation.
Shorter Run Times: Combined Programs
Simplified setup and reproducibility are not the only benefits of AFC. Productivity can also be improved by shortening analysis times which is possible through the use of pressure or flow programs and temperature programs. In the past, one would run a temperature program in order to separate a wide boiling range sample. Column flow was controlled by a pressure controller. As a column is temperature programmed, the flow will decrease with increasing temperature if the head pressure is constant. This means that one could only choose the optimum flow for the beginning, the middle or the end of the temperature program, therefore, chromatographic resolution was sacrificed. AFC solved this by providing a 5-step flow or pressure program which allows for optimum flow to be maintained throughout the temperature program, thereby decreasing the analysis time.
Automatic Split Ratio Calculation:
What a time saver !
Ease of operation and conservation of carrier gases are both achieved with our unique ability to set the split flow automatically from the keyboard. Simply enter the column dimensions, then the desired column flow rate or linear velocity and the split ratio, the system will automatically calculate the column inlet head pressure to achieve these set points. In addition, the split flow can be time programmed allowing the user the opportunity to decrease it alter injection in order to conserve carrier gas usage.
Simple, Interactive Control
All parameters including those of the AFC can be set through the standard menu driven GC-17A control software resident in the C-R7Aplus Personal Chromatopac. The C-P7Aplus uses our unique optical link interface to achieve simple, responsive control of the GC-17A and its standard floppy or hard disk for archival of GC-17A methods.
Automated Ideal Sample Injection and Control
The CC-17A may be combined with the AOC-17 (with or without OAK-1400 Automatic Sampler) for "ideal" sample handling. Ideal sample handling is the ability of the OAK-17 to inject samples in the best possible fashion for the injection technique being used. The AOC-17 achieves this through programmability of all injection parameters including injection speed and port dwell time while also offering several solvent flush injection techniques. The combination of the AOC-17 and the automated control of features of the GC-17A allows error free setup of conditions and optimization for the best possible analyses.
Control of a totally automated system is possible from the C-R7Aplus Chromatopac or a PC via an optional serial interface. The C-R7Aplus includes a Menu-driven GC/AOC Control Program as a standard feature: This combined with the C-R7Aplus's Batch Sample Processing utility provides for automatic processing of multiple standard and unknown samples. If customized automated control is desired, BASIC programming may be performed on C-R7Aplus which allows control of all GC-17A parameters through the use of simple Iogical key words. One such application might be to automatically optimize analytical conditions by varying certain parameters in a BASIC program.
Automatic Startup and Shut Down
Conservation of energy and carrier gas is becoming more and more important from a business standpoint in Iaboratory operations. The GC-17A addresses this by providing the user the opportunity to control on a time basis, when heaters and carrier gas flows are turned on and off. This is possible because 10 parameter files are stored in battery backed up memory and can be invoked using Start Time, Stop Time, Flovv Off Time, and Sleep Time functions automatically. These functions allow precious resources to be saved while ensuring that the analyst need not waste time waiting for the instrument to equilibrate.
Conditions Easily Viewed in Real Time
The backlit, liquid crystal display allows three parameters to be viewed simultaneously during real-time operation. The content is flexible and may be chosen by the user. Typical choices are temperatures, pressures, flows, and run time. This flexibility allows the user to quickly assess the status of the analysis in automated operation.
Powerful 5-Step Flow Pressure, and Temperature Programs
The ability to set up these programs in up to 5 steps provides the necessary flexibility to completely optimize a chromatogram from a separation and run time standpoint. Increased productivity naturally follows.
