In this Guide. . . This Installation and Operation Guide contains information for installing and using an effluent splitter on an Agilent 6890 gas chromatograph (GC). The G3180 splitter is intended for use with capillary columns and uses makeup gas to maintain adequate flows throughout the system. 1 Introduction This chapter describes how the splitter works, the GC and software requirements of the system and the contents of the installation kit. 2 Hardware Installation See this chapter for a

1 Introduction Overview Splitter installation is done in three steps: 1 Hardware installation. This gets the hardware installed and the gas flows connected. 2 Restrictor configuration. You can choose to use a typical, precalculated configuration or create a custom one using software tools supplied on a CD. 3 Restrictor and column installation. Using the results of step 2, cut the appropriate lengths of the appropriate diameter tubing for the restrictors. Install the restrictors and the analy

Introduction 1 How It Works The splitter divides the effluent from a column between two different detectors. The detectors can be operating at different pressures, that is, any mix of the following can be used: • Atmospheric pressure FID (flame ionization detector) TCD (thermal conductivity detector) NPD (nitrogen phosphorus detector) ECD (electron capture detector) FPD (flame photometric detector) � Below atmospheric pressure MSD (mass selective detector) � Above atmospheric pressure A

1 Introduction The column flow mixes with the makeup flow in the splitter. This mixture then flows through lengths of uncoated, deactivated, fused-silica tubing to each detector. These tubes act as flow restrictors. While the flow through each restrictor changes with oven temperature, the ratio of the two flows at any temperature is the same. Details The G3180B kit addresses several limitations of previous approaches to splitting column effluent between two detectors: Metal ferrules The spl

Introduction 1 Calculation of chromatographic parameters Because the pressure at the split point is known and constant, the chromatographic parameters can be calculated before setup. This is especially useful with GC/MSD setups, where there are limitations on the flow rates of carrier gas allowed into the MSD. If a method that was originally developed on an MSD is converted to a splitter setup, a new inlet pressure can be calculated to produce retention times very similar to the original me

1 Introduction GC Requirements The splitter mounts in an Agilent 6890 series GC. The splitter requires an electronically controlled pressure source such as the Three Channel Pressure controller (6890 option 205, 301, or 308) or a Pneumatics Control Module (PCM). Other Requirements The calculator requires Microsof®t Excel 97 (or later), which is not supplied with this kit. 12 Installation and Operation Guide
