Serinus 40 – V2

1. After this warm up has completed the instrument will immediately begin taking measurements refer to Section 3 2 3 2 Measurement The Serinus 40 NO Analyser is a dual channel monitoring instrument which means that it measures sample air through two different paths These two paths are used to measure NO Sample and NOx Sample Aux with the NO concentration resulting from a calculation of the difference between the two The instrument measures NO and NOx in groups of 10 5 of each it swaps between the channels five times each per cycle Before each cycle a background is performed to determine the level of fluorescence without NO present thus removing any background noise from the signal The sampling procedure follows Table 2 Sample cycle 5 times per cycle Instrument State Duration Description Sample Fill 3 sec Cell fills with NO sample Sample Measure 3 sec NO sample is measured Sample Fill Aux 3 sec Cell fills with NO sample Sample Measure Aux 3 sec NO sample is measured Operation Page 39 Serinus 40 User Manual 2 2 Table 3 Background cycle once per cycle Instrument State Duration Description Background Fill 8 sec Cell fills with background air Background Measure 3 sec Background air is measured Background Purge 4 sec Background air is removed from the cell and filled with NO sample Total cycle time is 75 sec 3 3 General Operational Information
