Page 7: Safety Practices And Hazards
Nieuwstadterweg 3 6136 KN Sittard (the Netherlands) General Operation of the Agilent ETC 60 electrothermal temperature controller and an atomic absorption (AA) spectrometer involves the use of an electrically heated quartz cell, high temperatures, compressed gases, and hazardous materials, including corrosive fluids. -
Page 8: Hazard Warnings
Covers which are retained by screws on the ETC 60 may be opened only by an Agilent field service engineer. The ETC 60 MUST be switched off at the power switch, and the mains cable disconnected from the mains supply BEFORE any attempt is made to remove or replace the cell in the workhead, or the cables connecting the workhead to the Temperature Control Module. -
Page 9: Chemical Hazards
Ensure that the voltage selector is correctly set for the specific mains power supply outlet that the ETC 60 will be connected to. You must do this before connecting the accessory. A blown fuse should be replaced with one of the size and rating stipulated in the text adjacent to the fuse holder. -

Page 21: Installing An Absorption Cell
Installing an Absorption Cell To install an absorption cell: Undo the latches on the ETC 60 workhead cover and open the cover. Carefully place the cell into the workhead. Ensure that the inlet stem is located in the groove at the front of the workhead. -

Fit the two lugs on the workhead bracket into the two holes on top of the burner adjuster. Holes on burner adjuster Lugs on workhead bracket Figure 12 Preparing to fit the workhead bracket Agilent Electrothermal Temperature Controller ETC 60 User’s Guide... - Page 23 Broken glass can cause severe cuts to hands. Handle the workhead with care, as the sidearm of the quartz tube is fragile and easily broken. Fit the ETC 60 workhead into the hole in the bracket and push down firmly to seat this in the bracket.
- Page 24 The system is now ready for use. The RS-232 connector on the back panel of the control module is used to download software upgrades to the ETC 60. Plug in the RS-232 cable (option) to this connector and connect the other end of the cable to your computer.

VGA. The ETC replaces the air-acetylene flame as a heat source to atomize the analyte hydrides. When using the Agilent ETC 60 you will need to select the ETC-60 option in the Vapor mode parameter on the Type/Mode tab of the Method Edit page. - Page 26 ‘Analytical Notes’ section. For details on caring for the workhead, refer to the ‘Maintenance’ section When the ETC 60 is operating, the quartz tube glows red. Most of this glow is caused by reflected light from the heater, although the sidearm does become warm.

Page 27: Power Up
Power Up Ensure that the ETC 60 is correctly installed as previously detailed, turn on the power switch to power up the module. The ETC 60 will perform a self-test that takes a few seconds. If all functions are operating correctly, the display will show the following: M V1.30 ETC-60 temperature controller... -
Page 28: Making Selections
If the temperature control module is switched on without the thermocouple connected, the ETC 60 will go into a permanent error state when the self test is complete. To clear this error: switch off the module, connect the thermocouple cable, and power up the ETC 60 temperature control module again. -

Select OK to accept the settings. Unattended Operation As there is no flame present, you can use the AA spectrometer, VGA 77, ETC 60, and an autosampler for unattended operation. When performing unattended operations ensure that all waste connections are CAUTION securely mated and that waste containers are large enough to accommodate all of the waste that will be generated during the unattended run period. -
Page 33: Shutdown Procedure
Always ensure that the workhead is allowed to cool before attempting to remove it from the sample compartment. The ETC 60 MUST be switched off at the power switch, and the mains cable disconnected from the mains supply BEFORE any attempt is made to remove or replace the workhead, or the cables connecting the workhead to the Temperature Control Module. - Page 34 Operation This page is intentionally left blank.

Page 35: Analytical Notes
Vapor mode parameter should be set to ETC-60, when using this accessory. The ETC 60 permits atomization of analyte hydrides at the appropriate temperature for each analyte. The temperature of the electrically heated quartz tube is generally lower than that of the flame heated quartz tube, and so the residence time of atoms in the quartz tube is longer than when a flame is used. -
Page 36: Arsenic
ETC 60. If mercury determinations are being carried out using the ETC 60, the standard flow through the cell must be used. When using the ETC 60 for mercury determinations there may be a slight loss of NOTE sensitivity in comparison to measurements made using the flow-through mercury cell. -
Page 37: Optimal Temperature Determination
Analytical Notes If condensation forms inside the cell, program the ETC 60 to operate at a NOTE constant temperature of approximately 100 °C. You can set the optimal isothermal temperature to suit your analytical requirements but never exceed 300 °C when analyzing for mercury. - Page 38 Analytical Notes This page is intentionally left blank.

Page 39: Maintenance
Daily Maintenance Due to the use of corrosive reagents in the vapor generation technique, the panels of the ETC 60 Temperature Control Module must be cleaned at the end of daily use with a soft cloth dampened with mild detergent solution. It is not necessary to clean the workhead. -
Page 40: Quartz Absorption Cell
Quartz Absorption Cell The quartz absorption cell of the ETC 60 has a finite lifetime, which is dependent upon the atomization temperature used and the effects of reagents and sample matrices. Since the quartz cell of the ETC 60 is heated under controlled conditions, an improvement in tube lifetime may result when compared to flame heating. -
Page 41: Replacing The Absorption Cell
Always ensure that the workhead is allowed to cool before attempting to remove or replace the cell. The ETC 60 MUST be switched off at the power switch, and the mains cable disconnected from the mains supply BEFORE any attempt is made to remove or replace the cell. -
