The primary advantage of in-situ analyzers is that they avoid gas transport issues. In-situ analyzers measure the properties of gases or liquids directly at the sampling location, meaning that the sample does not need to be transported to a separate analysis site. This direct measurement eliminates potential problems such as contamination, degradation, or changes in the sample composition that could occur during transport.

Additionally, in-situ analyzers often provide real-time data and immediate feedback on process conditions, allowing for quicker adjustments and more efficient operation. This capability is particularly important in applications where precise monitoring of gases is crucial, such as emissions control or process optimization.

While lower operational costs, ease of maintenance, and accuracy are important factors in evaluating analytical methods, the unique advantage of eliminating the complications associated with transporting samples stands out as a significant benefit of in-situ analyzers.
