7 How to Work With the Analyser

7.2.2.1 Measuring intervals of the sample streams 1 to 6

Here, the measurement intervals of the measurements per sample stream are selected. If a measure-

ment takes more time than the selected interval, the instrument will automatically select the next higher

interval. The following measurement intervals are available:

Possible measuring intervals

7.2.2.2 Filling time of the sample

This parameter determines the duration of the filling of the sample storage vessel before the measure-

ment (pumping time). A minimum of 30 seconds must be allowed for filling hoses and sample vessels.

7.2.2.3 Filling time of the acid

This parameter determines the duration of the filling of the acid before the measurement (pumping time).

7.2.2.4 Emptying time sample

Here, the duration of emptying the sample storage vessel can be set. The emptying of the sample stor-

age vessel requires at least 45 seconds.

7.2.2.5 Outgassing time (NPOC)

This parameter is only needed for the TOC direct method. The parameter determines the duration in se-

conds of stripping the sample in the sample receiver (TIC vessel) to blow out the TIC.

7.2.2.6 TC delay

This parameter determines the waiting time before a TC measurement (sampling).

7.2.2.7 TIC delay

This parameter determines the waiting time before a TIC measurement (sampling).

7.2.2.8 Preparation time of the injection loop

Here you can specify the duration in which the device aspirates part of the sample to guarantee the per-

manent filling of the tubes. The preparation time of the injection loop is at least 5 seconds.

Possible settings Description

1, 2, 3, 4, 5, 6, 10, 12, 15, 30 minutes Measurement interval in minutes

1, 2, 4, 6, 8, 12, 24 hours Measurement interval in hours

Fastest testing mode Shortest measuring frequency

Remote Deviation at the carrier gas outlet

Notice

Different parameters influence the maximum achievable measuring frequency. If an

interval is selected that can not be performed, the unit automatically selects the fastest

possible interval.
