Subject:
SGP/ACSM/C1 - Sample flow restricted
DataStreams:sgpaosacsmC1.b1, sgpaosacsmC1.00, sgpaosacsmC1.01, sgpaosacsmC1.a1
Description:
This period is between two failures of the carbon vane pump that pulls air through the 
instrument. During this time the tubing between the pump and ACSM collapsed and may have 
affected the sample flow rate. The collapsed tubing was replaced with a different type, one 
that is much stiffer and less prone to collapsing under vacuum.
Suggestions: 
Use data with caution
