WebInnovation in flow switching in gas chromatography (GC) provided by the Deans switch (DS), introduced in the late 1960s, has had a lasting and significant impact on the practice of GC. WebHello, im having a problem with a 2d GC using the Deans Switch system. Its a 8890 GC with 2 FIDs. The problem is that, when cutting peaks from the 1st dimension to the 2nd dimension (2nd column), all peaks on the 2nd dimensions get split into 2 peaks. Its not a inlet problem - if it was, all peaks would show up as 2 peaks also on the 1st column ...
