Hewlett Packard 7673
Uncompromising precision matched with consistently high productivity
Hewlett-Packard's 7673 automated liquid sampler system can be on-thejob, 24 hours a day, delivering exact precision with every injection.
Developed to enhance the performance and productivity of our industry-standard HP 5890 Series II Gas Chromatograph, the HP 7673 has three easily integrated components:
Automatic injector
Automatic sampler with 100-sample tray
Sample identification module
This system offers a range of flexible and affordable upgrade options with efficiency and convenience built in.
The HP 7673 Injector with three vial sampling improves chromatographic precision without the cost of a full-featured sample trag.
This first step in automation provides multiple benefits:
Automatic injection eliminates differences in manual injection techniques.
Fast injection mode dramatically reduces sample discrimination in vaporizing inlets.
Automated on-column injection virtually eliminates thermal decomposition of the sample.
When you need increased automation, the HP 7673 Injector with 100-sample tray increases laboratory productivity while providing flexibility of operation.
High priority samples can be analyzed with minimal operator intervention.
Samples can be analyzed in any sequence, with calibration and blank samples accessed periodically.
Samples can be heated or cooled, quadrant by quadrant.
By adding a second injector, you can make one GC do the work of two. The second injector lets you:
Run two sets of samples simultaneously through one GC.
Confirm a sample by running it on both inlets.
The HP 18587 Bar Code Sample Identification System assures that reports correctly match samples, eliminating sequence inaccuracies. Moreover, for convenience,
the sample code is printed on the chromatographic report.
Automating your chromatography system
Automation offers benefits in consistent and precise analyses, increased laboratory productivity, consistent temperature control, and the ability to per-form random or priority sampling.
Eliminate Needle Discrimination
Since Hewlett-Packard pioneered fast injection over five years ago, the HP 7673 fast injection mode has become the Standard for all gas chromatography automatic injection. Because the actual dwell time of the syringe in the injection port is approximately 100 milliseconds for one microliter, fast injection reduces sample discrimination caused by needle fractionation and improves peak area reproducibility. Fast injection can be paired with Hewlett-Packard's packed or Split/splitless inlets-specifically designed to take advantage of the injector's capabilities.
Increase Injection Flexibility
For those who want to mimic manual injection speed, the
HP 7673 Injector also has a slow injection mode.
Simplify Calibration and Purity Checks
With Hewlett-Packard data handling systems, the sequence of the samples selected by the HP 7673 robotic arm can be programmed to return the arm to a particular standard for periodic calibration or a blank sample to check system purity. Samples do not have to be run sequentially, avoiding the need to prepare multiple calibration and blank samples.
Analyze Priority Samples Fast
High priority samples can be introduced at any time for immediate analysis. Simply place the priority vial in the preselected position on the tray. After the priority Sample is analyzed, the programmed sequence picks up where it left off.
Enhancing Quantitative Precision
The injector, teamed with the Hewlett-Packard on-column inlet, reduces inlet-related discrimination and enhances quantitative precision because the sample is vaporized inside the column. Furthermore, thermally labile compounds do not decompose or rearrange because they are not exposed to high temperatures.
The HP 7673 Automatic Injector/ Sampler system offers innovative features that make your laboratory more productive and easier to operate.
Double Sample Throughput with One Chromatograph
Hewlett-Packard offers dual simultaneous injection, which allows you to inject samples into two inlets at the same time. You achieve twice as many analyses for each gas chromatograph, which saves analysis time, reduces the cost of hardware and maintenance, and frees bench space while providing excellent precision and accuracy.
You can process your samples in either of two modes-parallel throughput or sequential confirmation.
Automate All Your Hewlett-Packard Gas Chromatographs
The HP 7673 Automatic Injector/Sampler is compatible with Hewlett-Packard gas chromatographs, offering backward compatibility.
Moreover, the HP 7673 is lightweight and easily portable between Hewlett-Packard gas chromatographs. No gases, regulators, tubing, or expensive pneumatics just plug it in and the syringe and injection port are automatically aligned.
Furthermore, the injector removes easily for convenient injection port maintenance.
Assuring Positive Sample Identification
Identify Samples Correctly, Every Time
When you attach the HP 18587 Bar Code Sample Identification module to the HP 7673 sampling tray you eliminate transcription errors. This supports GLP standards by electronically transferring the bar code to your data handling system. The sample identification system reads and adapts to a wide variety of industry-standard bar code symbols.
Hewlett Packard 5970 B
General Description
The HP 5970B Mass Selective Detector (MSD) is a stand-alone capillary GC detector designed for use with a variety of gas chromatographs. It is compact and portable (mainframe weighs 54 kg), requires no cooling water or compressed air, and operates on standard 120-volt power. The detector mainframe includes the GC interface, an electron impact ion source, hyperbolic quadrupole mass filter, electron multiplier detector, power supply, drive electronics, and analyzer vacuum system. The detector can be factory configured for either right or left side sample inlet.
Real-time control of the MSD is done by the MSD electronics. Operating parameters are entered through the data system which also receives and processes the raw data from the MSD. Two data systems are available for use with the HP 5970B: the HP 59970C ChemStation and the HP 59870B RTE Data System (which uses HP 59872A GC/MS Software). The ChemStation is a single-user, single-tasking system while the RTE data system is a multi-user, multi-tasking system.
Software on both data systems includes programs which automatically adjust voltages in the ion source, calibrate mass assignment, and control scanning of the mass analyzer. Data acquisition programs allow the operator to monitor the total ion current, automatically storing the mass spectra of GC peaks as they elute, or to monitor several ions in the selected ion monitoring mode.
Data editing programs provide for plotting the mass spectra, tabulating spectra, and searching spectral libraries. Software for integration of peak areas allows quantitation of several ions. Also included is diagnostic software which allows the service specialist to set and monitor various voltages for troubleshooting and service, INET diagnostics, and calibration. Additional software options include an automated injection/edit/report package, and NBS Libraries.
Specifications
Mass Selection Scanning mode: Scans any mass range between 10 and 800 amu in 0.1 amu steps. Up to three mass ranges may be selected using time programming.
Resolution Unit resolution throughout mass range established automatically under computer control.
Scan Speed Eight user-selected scan rates with a maximum of 1500 amu/second with 0.1 amu mass resolution.
Sensitivity Typical performance for 1 ng of methyl stearate yields a signal-to noise ratio of better than 20:1 at m/z 298.3 when scanned at 380 amu/second between m/z 290 and 310.
Selected Ion Monitors up to 20 individually selected masses at one time. Up to Monitoring Mode 10 groups of 20 masses may be selected for each run using time programming.
Dwell Tinte User-selectable from a minimum of 10 milliseconds per m/z value up to a maximum of 32757 milliseconds.
Sensitivity Typical performance in selected ion monitoring: 10 pg of methyl stearate when monitoring m/z 298.3 for a dwell time of 50 mil liseconds, with a 10:1 signal-to-noise.
Detector Continuous dynode electron multiplier. Power supply to the multiplier is computer controlled. Maximum voltage is 3000 volts, settable in 200 volt increments.
Ion Source Electron impact source with electron energy of 70 eV. Two filaments are selectable to allow continued operation in the event of filament failure. Complete source is removable as an assembly for convenient cleaning.
Mass Filter Quadrupole mass filter consists of four molybdenum rods, 203 mm long, precisely formed to a hyperbolic shape.
Dynamic Range An FET logarithmic preamplifier provides five decades of dynamic range. In MSDs with RTE data systems, a linear preamplifier provides five decades of dynamic range.
Mass Axis Stability Mass axis stability of ±0.5 amu in eight hours.
Vacuum System Analyzer vacuum is maintained by an aircooled turbomolecular pump backed by a two-stage direct drive mechanical pump. Overall system pumping speed is approximately 60 liters per second for helium. The vacuum system can accommodate a capillary flow rate of 1.0 cc/minute (atmosphere) of helium. Pumpdown from (or venting to) atmosphere requires approximately 10 minutes. Time to reach operating temperature (or cool down for venting) is approximately one hour.
Optional ion gauge controller monitors pressure in the high vacuum chamber up to 1 x 10 -3 Torr. Typical chamber pressure is 5 x 10 -5 Torr at 0.5 cc/minute of helium.
Safety Features Automatic interrupt system provides protection against damage due to excess ion source pressure or electron multiplier output current, as well as filament or RFPA failure.
In addition, analyzer temperature zone and operating voltages are inter locked with turbo pump speed to prevent instrument damage due to operation at excess source pressure.
An elapsed time clock indicates service interval time for turbo pump preventive maintenance.
Temperature Control Ion source/analyzer temperature is controlled by a fixed temperature thermostatic controller. Ion source temperature is maintained at about 180-250°C.
Interface temperature is controlled by the gas chromatograph through the auxiliary zone controller or through a detector zone controller. Other external temperature control is also possible.
Recommended Interface operating temperature is from 100 to 300°C.
GC Interface Two options available are a capillary direct interface and an open- split Interface. With the capillary direct interface, the fused silica capillary column is inserted directly into the ion source. The interface options are offered in three versions. The 68 mm interface is designed for the HP 5710 or 5790 series GCs; the 94 mm interface is for the HP 5880 GC, and the 214 mm interface is for the HP 5890 GC. The interface is considered an extension of the GC; its operating parameters are controlled by the GC.
Temperature The MSD will operate within specifications in a temperature-Environment environment of 15 to 35°C.
Carrier Gas A regulated supply of high purity GC carrier gas is required. Minimum purity of 99.9995% is recommended. Molecular sieve trap is also recommended.
