Subject:
SGP/CCN/C1 - Problem with flow control regulation
DataStreams:sgpaosccnavgC1.c1, sgpaosccn100C1.a1, sgpaosccnavgC1.c2, sgpaosccn1colC1.b1,
sgpaosccnC1.a1, sgpaosccnC1.00
Description:
A problem with flow control regulation. The instrument was returned to manufacture DMT for 
repair. The column was found cracked and replaced. Data scans from 5/6/2016 15:36 to 
5/10/2016 16:00 use the default scan mode that steps from 0.2 to 1.0 %ss. After this time, 
the pyramid stepping scheme is implemented.
Suggestions: 
Do not use data. Use gRH Value Added Product (VAP)
