Introduction
In chromatography, retention times of components of the same injected sample are not constant. Indeed, phase ageing of the column varies in non linear and random ways depending on injected products and their concentration.Reasons of these variations in GC or LC
- Injection mode
- Gas control
- Temperature control
- Gas chromatograph reconditioning
- Injected product chemistry
- Sample purities
- Phase oxidation (O2 in carrier gas)
- Quality of pumps in HPLC
Upon repeating analysis, retention time differences of components will vary from seconds to minutes. Moreover if the analyzed product has hundreds of components separated by a few seconds on the chromatogram, the manual identification is long, difficult and is prone to human error.
Today even if a gas chromatograph has all the new electronic regulation developments of temperature and gas flow rates, it is unable to balance these complex variations.An automatic and accurate analysis is now possible with GC-LC CONCORDANCE !
