How do I calculate the number of theoretical plates in gas
Peak elution for the same column can also change in other situations, which will be discussed in other blogs. Biggest impact is seen when elution temperature changes. The elution temperature can have a big effect on peak elution order.... Co-elution is a very important concern in forensic chromatography. In a nutshell co-elution can be defined as when non-resolved (non-separated) compounds elute (come off) the column at the same time.

Higher elution temperatures may affect S/N especially if the columns starts to bleed. Lucky with the new generation phases (like Rxi), the columns can be used up to 350C and bleed is a minor issue. Lucky with the new generation phases (like Rxi), the columns can be used up to 350C and bleed is …...

How To Read Elution Peaks

Split peaks 2. Peak tailing 3. Broad peaks • Many peak shape issues are also combinations - i.e. broad and tailing or tailing with increased retention •Symptoms do not necessarily affect all peaks in the chromatogram •Each of these problems can have multiple causes Page 12 Peak Splitting Caused By Disrupted Sample Path Split or Double Peaks Normal Double Peaks Tip: Similar Effect Can be

  • upslope and downslope of peaks to determine compound purity. Thus, the peak purity is the ratio of the peak upslope and downslope spectra. A purity of less than 1.5 indicates similar spectrum along the peak and a purity of 1.5 or more indicates dissimilar spectrum along the peak that is typical of adulterated or co-eluting compounds. Among the three peaks (A, B, C) shown in Figures 1-a, the
  • Today we examine an approach to fitting curves to overlapping peaks to deconvolute them so we can estimate the area under each curve. We have a text file that contains data from a gas chromatograph with two peaks that overlap.
  • The specific elution is usually milder and proteins are more likely to retain their activity, but the slow elution, broad elution peaks, and the need to remove competing agent from the recovered protein are some of the drawbacks of this approach.
  • Peak elution for the same column can also change in other situations, which will be discussed in other blogs. Biggest impact is seen when elution temperature changes. The elution temperature can have a big effect on peak elution order.
