Common LC-MS/MS Applications

LC-MS/MS is widely used throughout drug development because of its sensitivity, specificity, and ability to quantify compounds and their metabolites in complex biological matrices.

Alturas supports LC-MS/MS applications including:

  • biomarker quantitation
  • NCE (new chemical entity) and/or metabolite quantitation
  • pharmacokinetic (PK) studies
  • toxicokinetic (TK) studies
  • preclinical sample analysis
  • bioavailability and bioequivalence studies
  • drug-drug interaction studies
  • clinical trial sample analysis
  • regulatory submission studies

Our workflows are designed to generate reproducible data that supports decision-making from early discovery through regulatory approval.

HRMS

Our high resolution mass spectrometry capabilities, typically as LC-HRMS/MS, support both qualitative and quantitative workflows. These methods are ideal for protein quantitation, metabolite identification, biomarker discovery, and nontargeted screening. When used to its full potential, HRMS can deliver precise mass accuracy and robust sensitivity to provide deeper insight across discovery and regulated studies.


GC-MS/MS Analytical Services for Specialized Detection

Scientists at Alturas Analytics employ GC-MS/MS techniques when LC-MS/MS methods are inappropriate to achieve complete detection of some substances encountered in therapeutic programs. Expert optimization of GC-MS/MS offers sensitive and selective detection methods for volatile and semi-volatile compounds.

GC-MS/MS services at Alturas include:

  • quantitative analysis of volatile and semi-volatile organic compounds
  • trace detection of impurities alongside metabolites and biomarkers in samples
  • sample analysis across a variety of complex matrices including plasma, urine, breath, and tissue extracts
  • GLP-compliant method development and validation informed by regulatory guidances

GC-MS/MS Applications:

  • analysis of low molecular weight drugs and their metabolites
  • chiral separations and impurity profiling
  • biomarker validation and metabolic pathway studies

Why GC-MS/MS with Alturas?

  • enable the analysis of compounds that are not suitable for LC-MS/MS methods
  • a successful history informing regulatory submissions that requiring GC-MS/MS data
  • under the same roof, combine GC-MS/MS, LC-MS/MS, and PK/TK workflows for complete bioanalytical support
