dephase_chrom-methods: Method dephase_chrom

In DanielQuiroz97/RGCxGC: Preprocessing and Multivariate Analysis of Bidimensional Gas Chromatography Data

Method dephase_chrom

Description

'dephase_chrom' shifts the retention time in the second dimension of the two-dimensional chromatogram. This procedure is usually applied in cases when part of peaks is splited in at the final and beginning of the second dimension. Also, the solvent effect and column bleeding can be removing by dephasing the chromatogram. The dephasing procedure is performing by splitting the chromagram with the relative value provided.

Usage

dephase_chrom(Object, rel_dephase)

## S4 method for signature 'GCxGC'
dephase_chrom(Object, rel_dephase)

Arguments

Object	a GCxGC class object
rel_dephase	a numeric value from 0 to 100 with the relative dephasing position.

Examples

 
 library(colorRamps)
 GB08_fl <- system.file("extdata", "08GB.cdf", package = "RGCxGC")
 GB08 <- read_chrom(GB08_fl, 5L)
 plot(GB08, nlevels = 150, color.palette = matlab.like,
      main = "No dephased chromatogram")
 GB08_d25 <- dephase_chrom(GB08, 25)
 plot(GB08_d25, nlevels = 150, color.palette = matlab.like,
      main = "25% dephased chromatogram")
