Useful strategies to improve the sensitivity and reliability of your GC or GC/MS analysis

Would you like to improve the sensitivity and reliability of your GC or GC/MS analysis when dealing with complex matrix samples? Often sample preparation is the critical step needed and appropriate sample preparation techniques not only make samples amenable for GC injection at concentrations suitable for detection, but also remove and prevent unwanted matrix components from accumulating and deteriorating on the GC and GC/MS flow path. 

Watch this presentation to discover some useful strategies such as choosing the right GC column and supplies, as well as what level of sample preparation, and maintenance is required for method reliability and analytical data quality, using challenging representative applications.
