mass_bias: mass_bias.

In IsoCor: Analyze Isotope Ratios in a 'Shiny'-App

mass_bias.

Description

mass_bias will calculate a correction factor K to scale isotopic ratios and thereby account for machine variance.

Usage

mass_bias(
  mi_amu = 0,
  si_amu = 0,
  method = c("Linear", "Russel", "Exponential"),
  f_value = 0
)

Arguments

mi_amu	atomic mass of MI isotope.
si_amu	atomic mass of SI isotope
method	Method to calculate the mass bias.
f_value	f_value to be used within the method calculation.

Details

Currently, 3 methods are available to calculate the mass bias, Linear, Russel and Exponential. They all depend on the atomic mass of the two ion traces and a f-value which can be provided as parameters to the function.

Value

A single numeric value K to be used for scaling.

Examples

IsoCor::mass_bias(32, 34, "Linear", 0.1)
