    δ O and δ H in liquid water. At the heart of the Picarro CWS is a porous membrane that enables diffusive sampling of water isotopes. By tightly controlling the physical factors that affect fractionation of liquid to vapor across a membrane, the CWS, when coupled to a Picarro isotopic water analyzer achieves stable and repeatable results from an automated analysis system.

  • Page 23: Calibration, Performance Verification & Best Practices

    Picarro recommends calibrating your CWS two to three times per day, this equates to 80 to 120 minutes, out of 1440 minutes per 24 hours, or a duty cycle of 5 to 8%. At 1 mL per minute, this equates to a maximum of 120 mL per day, or approximately 4 L of tertiary standard water consumption per month assuming the CWS is used every day of that month.
  • Page 24: Performance Verification

    Test 1: Measure a single source of water for 12 hours. Calculate the standard deviation of 5-minute averaged data bins over 12 hours. This test is used at Picarro to determine the performance prior to shipping. At the time of manufacture, the CWS system must yield values for this test of better than 0.1 ‰...

It is the change in the linear term of the fitted baseline, slope_shift relative to an empty cavity baseline which is measured at the Picarro factory. This column can be used to track potential spectral interference and data integrity.
