"Method ref": "FI03L_Mastgas",
"Standard method": "None",
"Inlet type": "Hat or hood",
"Inlet description": "Rain protected inlet with apertures in a machined piece of a PTFE rod; 157 m long sample line of 16/14 mm diam. PTFE tube; main flow 45 l/min; inlet + line heated at 5 C above air temp; 5 um PTFE filters at analyser inlet",
"Ozone correction": "Corrected for reaction with O3 in the inlet",
"Water vapor correction": "Corrected for water vapor quenching in CLD",
"Humidity/temperature control": "None",
"Humidity/temperature control description": "Passive, sample heated from atmospheric to lab temperature",
"Detection limit expl.": "Determined by taking 2 times precision (standard deviation) of instrument signal for zero air during calibration and divided by the square root of the number (10) of observations in 1 hour. No detection limit flag used",
"Measurement uncertainty expl.": "Calculated as expanded uncertainty (k=2). Includes reproducibility (signal precision) + systematic errors (accuracy): calibration gas accuracy, dilution accuracy and analyser span drift",
"Zero/negative values code": "Zero/negative possible",
"Zero/negative values": "Zero and negative values may appear due to statistical variations and calibration uncertainty below the detection limit",
