Troubleshooting

This chapter provides some hints to make troubleshooting easier.

For any detailed information how to handle or clean parts please see

Maintenance, p. 48

. For information on how to program the instru

ment see

Program List and Explanations, p. 77

7.1

Slope Error

Slope error is a calibration error. It occurs, if the correction factor

(slope) is > 2.0 or <0.5.

Note:

When mixing new reagents or standard solution:

• never use water contaminated with silica.
• do not use any glass containers to mix reagents or standard

solution.

If the calibration factor is too high do the following:

Check the programmed standard. See chap. 9,

5.1.2, p. 81

Prepare a new standard solution with demineralized water, use

SWAN stock solution only.

Clean all canisters and suction lances with a mix of demineral

ized water and one percent hydrochloric acid.

Prepare new reagents with SWAN original reagents, see

Refill or

replace Reagents, p. 49

If the calibration factor is too low do the following:

Prepare a new standard solution with demineralized water, use

SWAN stock solution only.

Clean all canisters and suction lances with a mix of demineral

ized water and one percent hydrochloric acid.

Check the pump delivery volume.
