Aztec 600 ISE ammonia and fluoride
Single-stream ion-selective analyzers
3.6.6 Fluoride Probe Preparation
The fluoride probe is supplied with a protective end cap to prevent the Lanthanum Fluoride crystal (forming its tip) from drying out and from being scratched or chipped. To prepare for use, remove the end cap and carefully rinse the tip in distilled water.
3.6.7 Fitting the Probe
Referring to Fig. 3.13, fit the ammonia or fluoride probe as follows:
1. Hinge down temperature-controlled block cover A to gain access to block B.
2. Position probe C into the recess in the temperature-controlled block (ensuring that probe tip D is fully inserted into flowcell E) and rotate retaining clip F to hold the probe in position.
3. Close the temperature-controlled block cover A.
4. Connect probe lead G to coaxial socket H.
