Page 13: Getting Started
Installation Overview Introduction The Agilent ETC 60 replaces the air-acetylene flame as a heat source to atomize the analyte hydrides in hydride generation methods of analysis. The running costs of the ETC 60 workhead are about 50% lower than those incurred in flame heating of the tube, due to the elimination of the costs of flame gases. -

With the Zeeman Workhead removed, hook the adapter fitted with the ETC 60 bracket on the top rear edge of the sample compartment. See Figure 25 on Page 24. - Page 24 The pins on the connector are sized differently and will only fit one way. 2. Fit the ETC 60 workhead into the hole in the bracket and push down firmly to seat it in the bracket. See Figure 20 on Page 21.
- Page 25 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. This connection allows direct control of the temperature settings from within the SpectrAA software, version 5 or later.

‘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 30: 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 31: Error On Startup
The above sequence of displays indicates that the ETC 60 is unable to be operated normally due to the error. New software can be downloaded to the ETC 60 from a PC by the serial interface. Contact Agilent for more information or to obtain assistance from an Agilent field service engineer. -

Page 35: Unattended Operation
Operation 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 36 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 37: 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 38: Arsenic
Add the oxygen directly before the hydride vapor enters the tube. Mercury The flow-through mercury cell will not fit inside the workhead of the ETC 60. If mercury determinations are being carried out using the ETC 60, the standard flow through the cell must be used. -
Page 39: Optimal Temperature Determination
1. Set up the instrument and install the ETC 60 as described in the ‘Getting Started’ section. 2. Set the temperature to 300 °C (100 °C for mercury) and wait for the ETC 60 to reach the temperature. 3. Go to the Instrument parameters page, and set the Measurement time to read 30 s, four replicates, and Delay time to 0 s. - Page 40 Analytical Notes This page is intentionally left blank.

Page 41: 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 42: Quartz Absorption Cell
Maintenance 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 43: Removing The Workhead
Maintenance If the ETC 60 has been operating, allow the workhead to cool down to ambient room temperature. Sharp Objects WARNING 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. - Page 44 Maintenance Removal of the workhead is the reverse of the installation procedure outlined in ‘Installing the Workhead’ section, Page 19.
