Who are the Target Customers?
Typical 7820A customers can be found across all industries:
– Budget limited
– Routine testing typically with local (non‐international) methods (QA/QC)
– Not a high throughput lab
– Generally small to medium size organizations
– Government testing labs at local district level
– Need basic GC functionality with just “good enough” performance

EPC Benefits
Ease of use No need for bubble meter and stop watch for setting gas flows. For switching between methods, the gas flows are saved with the method. This includes inlets and detectors.
Better Quality Data EPC technology allows better retention time and peak area repeatability from run to run.
