Defiant’s Cutting-Edge FROG Technology
Defiant Technologies has been providing affordable, innovative chemical detection systems since 2005.
How can we make our FROG Portable Gas Chromatograph GC so small? Let’s take a look inside.
End Result Chromatogram
The signal from the PID forms a picture over time, increasing when analyte is detected and decreases when analyte has left the detection stage. The picture is formed over the time at which all the analytes are introduced into the column to the end of the analysis and that picture is called a chromatogram. Each of the peaks in the chromatogram corresponds to one of the analytes detected by the system. The time at which the peak crests is called the retention time and the size of the peak corresponds to the concentration.
