what does it mean with Linear range in detector of Gas Chromatography?
thanks!
thanks!
The linear range of a detector in GC refers to the range of concentrations of a particular compound that can be accurately measured by the detector. This range is typically determined by the sensitivity and dynamic range of the detector.
The linear range is determined by analyzing a series of known concentration samples of the compound and plotting the detector response against the concentration. The resulting curve will show the linear range of the detector, where the response is directly proportional to the concentration.
The linear range is important because it determines the accuracy and reliability of the results obtained from the GC analysis. If the concentration of a compound falls outside the linear range of the detector, the results may not be accurate and may lead to incorrect conclusions.
Yes, the linear range can be extended by adjusting the parameters of the detector or by using a different detector with a wider dynamic range. However, it is important to note that extending the linear range may also affect the sensitivity and selectivity of the detector.
The linear range of a detector can be affected by factors such as the type of detector used, the sensitivity and dynamic range of the detector, the type and concentration of the compound being analyzed, and the operating conditions of the GC system (such as temperature and flow rate).
