  • Page 14: Chromatography Using A Gc

    Getting Started Chromatography Using a GC Chromatography is the separation of a mixture of compounds into individual components. There are three major steps involved with separating and identifying components of a mixture using a GC. They are: 1 Injecting a sample into the GC. (This takes place at the inlet.) 2 Separating the sample into individual components.

  • Page 15: Inlets

    Getting Started Inlets Inlets are where samples are injected into the GC. The Agilent 8890 GC can have a maximum of two inlets, identified as Front Inlet and Back Inlet. The following inlet types are available: • Split/splitless inlet (SSL) •...

  • Page 16: Gc Columns And Oven

    The Agilent 8890 GC can accommodate up to six columns, identified as Column #1 through Column #6. The 8890 will have six Smart ID Key slots on the front of the instrument. These keys hold configuration information about the columns on the system. The Column Smart ID Keys will define column information that could be transferred between GCs.

  • Page 17: Detectors

    Getting Started Detectors Detectors identify the presence of compounds as they exit the column. As each compound enters the detector, an electrical signal proportional to the amount of compound detected is generated. This signal is generally sent to a data analysis system—such as Agilent OpenLAB CDS ChemStation edition—where it shows up as a peak on a chromatogram.

  • Page 102: Gc Output Signals

    Methods GC Output Signals Signal is the GC output to a data handling device, analog or digital. It can be a detector output or the output from flow, temperature, or pressure sensors. Two signal output channels are provided. Signal output can be either analog or digital, depending on your data handling device. Analog output is available at either of two speeds, suitable to peaks with minimum widths of 0.004 minutes (fast data rate) or 0.01 minutes (normal rate).
  • Page 103 Methods This is used to correct baseline elevation or offsets. A common application is to correct a baseline shift that occurs as the result of a valve operation. After zeroing, the analog output signal is equal to the Value line of the parameter list minus the Zero setpoint. Zero can be programmed as a run time event.

    Methods Relative noise level Excess noise (due to flow, oven temperature, detector block temperatures, etc.) Faster data rates Slower data rates Column compensation In temperature programmed analysis, bleed from the column increases as the oven temperature rises. This causes a rising baseline which makes peak detection and integration more difficult.

  • Page 108: Test Plot

    Methods All conditions must be identical in the column compensation run and the real run. The same detector and column must be used, operating under the same temperature and gas flow conditions.

    14 Flow and Pressure Modules Restrictors The Aux EPC and aux PCM channel use frit-type restrictors to allow accurate flow control.To work properly, there must be adequate flow resistance downstream of the pressure sensor. Each channel provides a frit-type restrictor. Four frits are available. Table 23 Auxiliary channel frits Frit marking Flow resistance...

  • Page 204: Selecting A Frit

    14 Flow and Pressure Modules Selecting a frit The frits change the control range of the channels. The objective is to find a frit that allows the required range of flows at reasonable source pressures. • For an auxiliary channel ordered as an option (part of the GC order), use the frit supplied by the factory.

  • Page 205: Example: Using The Pcm Channels

    14 Flow and Pressure Modules Example: Using the PCM Channels The two channels in a PCM are different. Channel 1 is used to supply a pressure. Channel 2 may be used in the same way, but can also be used to maintain a pressure by reversing the input and output connections.

  • Page 206: Pids

    14 Flow and Pressure Modules PIDs The behavior of a pressure control module is governed by a set of three constants, called P (proportional), I (integral), and D (differential). Certain gases or special applications (such as headspace vial pressurization, flow splitter, and backflush applications) require different PIDs than those provided at the factory.

  • Page 209: About The Split/Splitless Inlet

    15 Inlets About the Split/Splitless Inlet This inlet is used for split, splitless, pulsed splitless, or pulsed split analyses. You can choose the operating mode from the inlet parameter list. The split mode is generally used for major component analyses, while the splitless mode is used for trace analyses. The pulsed splitless and pulsed split modes are used for the same type of analyses as split or splitless, but allow you to inject larger samples.

    15 Inlets About the Multimode Inlet The Agilent Multimode (MMI) Inlet System has seven operating modes: • The split mode is generally used for major component analyses. • The pulsed split mode is like the split mode, but with a pressure pulse applied to the inlet during sample introduction to speed the transfer of material to the column.

  • Page 214: About The Purged Packed Column Inlet

    15 Inlets About the Purged Packed Column Inlet This inlet is used with packed columns when high-efficiency separations are not required. It can also be used with wide-bore capillary columns, if flows greater than 10 mL/min are acceptable. If the columns are not defined (packed columns and undefined capillary columns), the inlet is usually flow-controlled.

  • Page 215: About The Cool On-Column Inlet

    15 Inlets About the Cool On-Column Inlet This inlet introduces liquid sample directly onto a capillary column. To do this, both the inlet and the oven must be cool at injection, either at or below the boiling point of the solvent. Because the sample does not vaporize immediately in the inlet, problems with sample discrimination and sample alteration are minimized.

  • Page 216: About The Ptv Inlet

    15 Inlets About the PTV Inlet The Agilent Programmed Temperature Vaporization (PTV) Inlet System has six operating modes: • The split mode is generally used for major component analyses. • The pulsed split mode is like the split mode, but with a pressure pulse applied to the inlet during sample introduction to speed the transfer of material to the column.

  • Page 217: About The Volatiles Interface

    15 Inlets About the Volatiles Interface The volatiles interface provides a simple, reliable way to introduce a gas sample into your GC from an external device such as a headspace, purge and trap, or air toxic sampler. Manual syringe injections cannot be made with this interface. The interface has a small volume and is highly inert, ensuring high sensitivity and resolution for applications requiring trace level detection.

    15 Inlets About the VI splitless mode This mode is used to concentrate sample at the head of the GC column during desorb. Purge timing delay must take into consideration the volume of the loop or trap in the external sampler plus the transfer line versus desorb/total flow rate.
  • Page 221 15 Inlets During sampling Pressure upsets caused by switching valves and trap restrictions in the external sampling device can cause fluctuations in column flow rates. To compensate for this, the interface is flow controlled during sampling time. The sampling flow rate is calculated from the pressure setpoint that is active when sample introduction begins.
