General notes
Guidelines for photometric measurements
Vials, caps and stirring rods should be cleaned thoroughly 1. after each analysis to prevent
interference. Even minor reagent residues can cause errors in the test result.
The outside of the vial must be clean and dry before starting the analysis. Clean the outside 2.
of the vials with a towel to remove fingerprints or other marks.
Zero calibration and test must be carried out with the same vial as there may be slight 3.
differences in optical performance between vials.
The vials must be positioned in the sample chamber for zeroing and test with the 4.
on the vial aligned with the mark on the instrument.
Always perform zeroing and test with the vial cap tightly closed. Only use the cap with 5.
a sealing ring.
Bubbles on the inside wall of the vial lead to incorrect measurements. To prevent this, 6.
remove the bubbles by swirling the vial before performing the test.
Avoid spillage of water into the sample chamber because this can lead to incorrect test 7.
results.
Contamination of the transparent cell chamber can result in incorrect readings. Check 8.
at regular intervals and – if necessary – clean the transparent cell chamber using a moist
cloth or cotton swab.
Large temperature differences between the instrument and the environment can lead to 9.
errors – e.g. due to the formation of condensation in the cell chamber or on the vial.
To avoid errors caused by stray light do not use the instrument in bright sunlight.10.
Always add the reagent tablets to the water sample straight from the foil without touch-11.
ing them with fingers.
The reagents must be added in the correct sequence.12.
mark
Method notes
Prior to measurement ensure that the sample is suitable for analysis (no major interferences) •
and does not require any preparation i.e. pH adjustment, filtration etc.
Reagents are designed for use in chemical analysis only and should be kept well out of •
the reach of children.
Ensure proper disposal of reagent solutions.•
Material Safety Data Sheets are available on request •
