Overview

The API 5000 system is designed for quantitative analysis of small molecules.

This application involves measurement of specific molecular weight compounds, usually a drug or metabolite in urine or other body fluid, and their resulting fragment ions for determining the exact quantity of the compound in the sample of interest. Quantitation is performed using a standard curve of mass spectrometer signal intensity for various known concentrations of the compound. The signal in the test sample is compared to the standard curve to determine the concentration.

The typical scan type used for this application in the API 5000 system, as well as all triple quadrupole instruments, is MRM (Multiple Reaction Monitoring).

Features of the Instrument

The API 5000 LC/MS/MS system combines all of the features of the API 4000™ LC/MS/MS system with the additional benefits of improved sensitivity and enhanced signal-to-noise ratio. It allows comprehensive analysis of biopharmaceutical compounds and it has the specificity needed for new drug development. It has the following features:

  • A wide diameter intake orifice which improves sensitivity by flowing more ions into the vacuum chamber.
  • A QJet® ion guide that prefocuses the ions before they enter the vacuum chamber for higher sensitivity and signal-to-noise ratio.
  • Improved Q2 lenses reduce CAD gas leakage into the vacuum chamber and improve sensitivity and signal-to-noise ratio.
  • Higher quadrupole operating frequency, which improves ion transmission and increases sensitivity, especially for low ion masses.
  • Higher sensitivity in all RF/DC scan modes.
  • Scanning in a mass range of m/z 5 - 1250 in quadrupole mode.
  • Enhanced resolution at reduced scan speeds.
  • Detector type: Pulse Counting CEM
  • Ionization Sources: TurboIonSpray, APCI, DuoSpray, PhotoSpray
  • Scan types: Q1 MS, Q3 MS, Product Ion, Precursor Ion, Neutral Loss or Gain, MRM
  • Highest sensitivity for small molecule analysis
  • Lowest limits of detection for DMPK and ADMET studies
  • Robust, high-throughput platform for all stages of pharmaceutical development
  • Accuracy and precision for quantitative analysis
  • Eliminates Cross-Contamination


For pharmaceutical and pharmacokinetic samples, MS/MS has the sensitivity and specificity needed to analyse hundreds of samples per day without requiring extensive sample preparation.
