Liquid Chromatography Data Processing Device Using Logarithmic Axes

The patent transforms the traditional two-dimensional presentation of chromatography data into a three-dimensional visualization system. The third dimension represents the influence of column filler particle size on separation performance, allowing users to intuitively perceive the relationship between particle size, flow velocity, and theoretical plate number. This dimensional transformation resolves the contradiction by providing comprehensive visualization without increasing processing complexity.

The patent introduces a new parameter representation method that visualizes the C term in the van Deemter equation as a function of particle size. By changing how particle size influence is parameterized and displayed, the system makes previously hidden relationships visible. This parameter transformation approach enables intuitive understanding of particle size effects without complicating the data processing methodology.

The patent applies local quality enhancement by selectively emphasizing different aspects of the chromatography parameters in different regions of the visualization. The system highlights the relationship between flow velocity and theoretical plates in specific zones, while separately illustrating the impact of column length and particle size. This localized information presentation improves measurement precision without overwhelming the user, making the complex relationships easier to understand.

The patent introduces an intermediary visualization layer that mediates between raw chromatography data and user understanding. This intermediate representation transforms complex multi-parameter relationships into an intuitive graphical format that clearly shows how flow velocity, column length, and particle size collectively influence theoretical plate number. The intermediary visualization resolves the contradiction by bridging the gap between precise measurement data and ease of interpretation.

The patent applies preliminary action by pre-calculating and pre-visualizing the C term influence and particle size effects before the user performs detailed analysis. The system proactively processes the van Deemter equation components and prepares the particle size influence data in advance, making this information immediately available in the graphical display. This preliminary processing ensures that no critical information is lost during analysis while maintaining reliable separation performance evaluation.

The patent implements a nested information structure where the C term influence and particle size effects are embedded within the overall separation performance analysis. The visualization nests multiple levels of information: the outer layer shows general separation performance, while inner layers reveal the specific contributions of the C term and particle size. This nested approach preserves all critical information while maintaining clear and reliable analysis without information loss.
