The source has several sharp pieces which can pierce your skin including the APCI corona needle, vaporizer sensor and counter current electrode. 1 If the source to be installed is an APPI source, disconnect the multimode high voltage PCA RS-232 serial cable from the serial port B connector of Smart Card. 2 Unscrew and remove the multimode spray shield with the field shaping electrodes. 3 Install the new source and the standard spray shield, making sure that the hole in the spray shield is in the 12 o'clock position. 4 For APCI and APPI ion source, connect the vaporizer heater cable and the APCI high voltage cable. For the APPI source, connect the RS-232 cable to the serial port B connector of Smart Card. 5 For all sources, reconnect the nebulizer gas line tubing and the LC/MS sample tubing. 14 Multimode Source for 6100 Series Single Quad LC/MS Set-Up Guide Installation 1 To convert from ESI, APCI or APPI to the multimode source To convert from ESI, APCI or APPI to the multimode source If you are installing this source on this instrument for the first time, follow the steps in "Installation" on page 7. 1 Switch to the MSD Tune view. 2 Select Instrument/Set Spray Chamber and set all gas flows and temperatures to 0. • Drying Gas (L/min) • Nebulizer Pressure (psig) • Drying Gas Temperature (°C) • Vaporizer Temperature (APCI source only) • Lamp Off (APPI source only) 3 Wait for the source to cool (until temperatures are at least below 100°C). 4 Disconnect the nebulizer gas tubing from the currently installed ion source. 5 Disconnect the LC/MS sample inlet tubing. 6 If the APCI or APPI source is installed, remove the APCI vaporizer heater cable and APCI high voltage cable. 7 If the APPI source is installed, remove the serial port B RS-232 cable. 8 Remove the currently installed ion source. 9 Unscrew and remove the spray shield. See Figure 11. Do not touch the multimode source or the capillary cap. They may be very hot. Let the parts cool before you handle them. WARNING CAUTION WARNING Do not insert fingers or tools through the openings on the multimode chamber. When in use, the capillary and capillary cap are at high voltages up to 4 kV.

If needed, moisten a clean cloth with isopropyl alcohol and wipe the capillary cap. See Figure 12. Capillary cap Figure 12 Spray shield removed. 11 Place the capillary cap back on the capillary. 12 Install the new spray shield with field shaping electrodes. See Figure 13. 16 Multimode Source for 6100 Series Single Quad LC/MS Set-Up Guide NOTE Installation 1 To convert from ESI, APCI or APPI to the multimode source Figure 13 Multimode spray shield 13 Screw the multimode spray shield into the holder for the spray shield. See Figure 14. Field shaping electrode 9 o'clock position Field shaping electrode 6 o'clock position Figure 14 Multimode spray shield installed The field shaping electrodes should be in the nine o'clock and the six o'clock position. Loosen the end plate screws on each side to adjust the field shaping electrodes position. 14 Remove the shipping cover from the multimode source spray chamber. Multimode Source for 6100 Series Single Quad LC/MS Set-Up Guide 17 1 Installation To convert from ESI, APCI or APPI to the multimode source Figure 15 Multimode Spray Chamber 15 Install the spray chamber on the spray chamber mount. Figure 16 Multimode source with I-Button 16 Install the nebulizer on the multimode source spray chamber. 18 Multimode Source for 6100 Series Single Quad LC/MS Set-Up Guide Installation 1 To convert from ESI, APCI or APPI to the multimode source Figure 17 No nebulizer on top of the multimode source 17 Connect the 1/8-inch nebulizer gas tubing from the LC/MS mainframe to the nebulizer gas fitting. See Figure 18. Sample Tubing Nebulizer zero dead volume Nebulizer gas fitting Figure 18 Nebulizer with gas tubing connected Multimode Source for 6100 Series Single Quad LC/MS Set-Up Guide 19 1 Installation To convert from ESI, APCI or APPI to the multimode source WARNING 18 Connect the LC/MS sample tubing to the LC/MS diverter valve inlet filter. See Figure 19 on page 20. The LC/MS Liquid Chromatograph diverter valve is an integral part of the G1978B safety system. The LC mobile phase flow must always be connected to the diverter valve inlet filter. Never bypass the diverter valve and connect directly to the nebulizer. If the diverter valve is used in a manner not specified by Agilent Technologies, the protections provided by the diverter valve may be impaired.
