RetentionIndex: Non-Isothermal Retention Index Calculation

In OrgMassSpecR: Organic Mass Spectrometry

Description

Determine the non-isothermal (temperature-programmed) gas chromatographic retention index of a target compound based on the retention times of adjacent n-alkanes.

Usage

RetentionIndex(n, target, preceding, following)

Arguments

n	the number of carbon atoms in the n-alkane eluting prior to the target compound.
target	the retention time of the target compound
preceding	the retention time of the n-alkane eluting prior to the target compound.
following	the retention time of the n-alkane eluting after the target compound.

Details

The retention time units can be either seconds or minutes, but should be consistent. The n-alkanes eluting before and after the target compound should differ by one carbon atom. This equation does not apply to isothermal separations or when the n-alkane series contains only odd or even carbon atoms.

Value

A vector giving the retention index.
