I'm using an online GC1530A for analysis of my reactor product stream. Recently, the GC quit functioning properly. When I run the GC from the software, the GSV never actuates and injects a sample. However, if I go use the front panel to manually turn on the GSV on and start a run, the valve actuates and the GC works as designed. What could be wrong with my software and/or GC that is preventing the programmed method from injecting sample?
Thanks in advance!
