Installation
• For a two-point calibration, the standards are positioned with the measurement series
on a sample tray for 36 sample containers as follows:
Position 33: 1st low standard, e.g. 0.5 mg/L TN
B
GCZ 100
Position 34: 2nd low standard, e.g. 30 mg/L TN
B
GCS 050
Position 35: 1st high standard, e.g. 30 mg/L TN
B
GCS 050
Position 36: 2nd high standard, e.g. 100 mg/L TN
B
GCS 100
The low standards can be selected freely in the range 0.5–30 mg/L TN
B
; the high
standards can be selected freely in the range 30–150 mg/L TN
B
.
Single and double determinations can be carried out. For double determinations, the
sample is drawn from a container twice. The settings refer to the whole sample tray.
The following table and illustration show an example of a sample tray load for a two-point
calibration:
