1 Installation Installation Installation Step 1. Prepare to install The Multimode Enablement Kit, G1978-60451, is shipped with the multimode source. This kit needs to be installed before the multimode source is used. Note that the multimode source and its accessories are to be installed by an Agilent Customer Engineer.
Installation Step 2. Install the HV control PCA and cables Figure 2 1 From left to right: G1946-80058, G1960-60802 and G1960-60856 Step 2. Install the HV control PCA and cables 1 Turn off the system power and remove the system power cord. The power cord should be kept intact if the vacuum control switch box is used. The switch box is intended to keep the vacuum on while a service engineer works on the electronics. The switch box is for service engineer use only.
1 Installation Step 2. Install the HV control PCA and cables Figure 4 Connecting the valve PCA to the multimode HV power supply. 6 Install the APCI HV power supply. The APCI HV power supply is located at the end of the AUX Module. 7 Connect ribbon cable between the valve PCA and Vcap/Vchamber power supply. Figure 5 Connecting the valve PCA to the Vcap/Vchamber power supply. 8 Connect the Vcap and Vchamber cables to the Vcap/Vchamber power supply.
Installation Step 2. Install the HV control PCA and cables Figure 6 1 Connecting the Vcap and Vchamber cables to the power supply. 9 Connect the long ribbon cable, p/n G1960-60802, from the APCI HV power supply to the valve PCA. Figure 7 Connecting the APCI HV power supply to the valve PCA. 10 Insert one end of the APCI Needle Interlock cable, G1960-60856, through the slot at the front of the system and then plug it to the APCI HV connector.
1 Installation Step 2. Install the HV control PCA and cables 11 Insert the cable, G1960-60858, to the top slot and attach it to the chassis. Plug the other two ends into the multimode HV PCA. Figure 9 Connecting the HV PCA to the chassis. 12 Close the AUX Module cover and reconnect all cables. 13 Install the multimode source onto the system and connect all connectors. Figure 10 Installing the multimode source (left) and connecting all connectors. 14 Put back the side, top, front and CDS cover.
Installation Changing Sources 1 Changing Sources To remove the multimode source Do the following steps to remove the multimode source. 1 Turn off the multimode source temperatures and flows: a Change the Context view to Acquisition. b Click the MS QQQ tab. c Turn off all voltages and temperatures in the Source tab. WA R N I N G Do not touch the multimode source or the capillary cap. They may be very hot. Let the parts cool before you handle them.
1 Installation To convert from multimode to ESI or APCI To convert from multimode to ESI or APCI WA R N I N G Never touch the source surfaces, especially when you analyze toxic substances or when you use toxic solvents. The source has several sharp pieces which can pierce your skin including the APCI corona needle, vaporizer sensor and counter current electrode. 1 Unscrew and remove the multimode spray shield with the field shaping electrodes.
Installation To convert from ESI or APCI to the multimode source 1 To convert from ESI or APCI to the multimode source CAUTION If you are installing this source on this instrument for the first time, follow the steps in “Installation” on page 7. 1 Turn off the multimode source temperatures and flows: a Change the Context view to Acquisition. b Click the MS QQQ tab. c Turn off all voltages and temperatures in the Source tab. 2 Wait for the source to cool (until temperatures are at least below 100°C).
1 Installation To convert from ESI or APCI to the multimode source Standard spray shield Capillary cap Figure 11 Standard spray shield and capillary cap for ESI or APCI 8 Remove the capillary cap. If needed, moisten a clean cloth with isopropyl alcohol and wipe the capillary cap. See Figure 12. Capillary cap Figure 12 Spray shield removed. 9 Place the capillary cap back on the capillary. 10 Install the new spray shield with field shaping electrodes. See Figure 13.
Installation To convert from ESI or APCI to the multimode source Figure 13 1 Multimode spray shield 11 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 NOTE Multimode spray shield installed The field shaping electrodes should be in the nine o’clock and the six o’clock positions.
1 Installation To convert from ESI or APCI to the multimode source 12 Remove the shipping cover from the multimode source spray chamber. Figure 15 Multimode Spray Chamber 13 Install the spray chamber on the spray chamber mount. I-Button Figure 16 Multimode source with I-Button 14 Install the nebulizer on the multimode source spray chamber.
Installation To convert from ESI or APCI to the multimode source Figure 17 1 No nebulizer on top of the multimode source 15 Connect the 1/8-inch nebulizer gas tubing from the LC/MS mainframe to the nebulizer gas fitting. See Figure 18.
1 Installation To convert from ESI or APCI to the multimode source 16 Connect the LC/MS sample tubing to the LC/MS diverter valve inlet filter. WA R N I N G 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.

2 Performance Verification To review methods and run worklist To review methods and run worklist You use the multimode source in Positive MRM Mode. 1 Verify that the Collision Cell gas flow rate produces a high vacuum gauge reading in the range of 2.7 to 3.3 x 10e-5 torr. To view the high vacuum gauge reading, click the Cell tab in the Tune Context and check that the high vacuum gauge reading is within range. If not, see “To reset the Collision Cell gas flow rate” in the Triple Quad Installation Guide.
