Overview

MobiLipid provides R Markdown workflows and a labeled-lipid reference library for CCS quality control in ion-mobility MS lipidomics. It estimates bias and class/adduct-specific correction functions. Correction functions are fitted by linear regression.

Scope and considerations

Designed for

  • Internal-standard-based CCS assessment and correction.

Not designed for

  • Raw spectrum processing, lipid identification or metabolic flux estimation.

Important requirements

  • Ion-mobility measurements of samples spiked with uniformly 13C-labeled lipid standards.
  • R/RStudio and documented dependencies; correction needs at least three standards per supported class/adduct combination.

Considerations

  • Vendor-required instrument calibration remains necessary.
  • Correction scope depends on represented lipid classes and adducts; do not extrapolate validation to all lipids.
