Maintenance and Troubleshooting
62 Agilent 5100 and 5110 ICP-OES User’s Guide
To rinse demountable torches:
1 Thoroughly flush the inside and outside of the torch quartz
components, including through the gas holes, with deionized
water (18 MΩ.cm) using a wash bottle to direct the water stream.
Drying the torch
Oven drying is not recommended. It is not as effective at removing
moisture as using compressed air or nitrogen.
To dry one piece torches:
1 Hold the torch inverted (with the ball joint connector at the top).
See Figure 16A.
2 Blow clean compressed air or nitrogen through the three gas
supply ports (two on the base and through the ball joint
connector) to remove moisture.
3 Ensure that all moisture is removed before refitting the torch
into the instrument.

To dry demountable torches:
1 Blow clean compressed air or nitrogen through the quartz tube,
injector, torch body and the three gas holes (see Figure 16) to
remove moisture.
2 Ensure that all moisture is removed before reassembling the
torch.
