Get definitions for internal standards

Description

internalStandards returns a table with metabolite standards available in commercial internal standard mixes. The returned data frame contains the following columns:

• "name": the name of the standard

• "formula_salt": chemical formula of the salt that was used to produce the standard mix

• "formula_metabolite": chemical formula of the metabolite in free form

• "smiles_salt": SMILES of the salt that was used to produced the standard mix

• "smiles_metabolite": SMILES of the metabolite in free form

• "mol_weight_salt": molecular (average) weight of the salt (can be used for calculation of molar concentration, etc.)

• "exact_mass_metabolite": exact mass of free metabolites

• "conc": concentration of the metabolite in ug/mL (of salt form)

• "mix": name of internal standard mix

Usage

internalStandards(mix = "QReSS")

Arguments

mix	character(1) Name of the internal standard mix that shall be returned. One of internalStandardMixNames().
