MtoZ Biolabs’ Acetonitrile, LC-MS Grade delivers exceptional purity and consistent performance, providing a reliable mobile-phase foundation for high-sensitivity LC-MS analyses.
Product Overview
In liquid chromatography-mass spectrometry (LC-MS) analyses, the purity of the mobile-phase solvent directly determines background noise levels, chromatographic peak shape, and the sensitivity and accuracy of mass spectrometric detection. When conventional or low-purity acetonitrile is used, the following issues commonly arise:
1. High Background Noise and Interfering Peaks
UV-absorbing impurities, organic residues, or trace metal ions present in impure solvents can generate persistent chemical background noise and difficult-to-interpret ghost peaks in mass spectra. These interferences severely compromise the detection and accurate quantification of target analytes, particularly low-abundance peptides or metabolites in LC-MS workflows.
2. System Contamination and Component Degradation
Non-volatile residues in low-quality solvents can gradually accumulate within the LC flow path, injection valves, chromatographic columns, and the MS ion source. This buildup may lead to increased backpressure, peak tailing, and ion source contamination, ultimately increasing instrument maintenance frequency and operational costs.
3. Batch-to-Batch Variability Affecting Reproducibility
Fluctuations in solvent quality can cause unstable chromatographic retention times, making cross-batch and inter-laboratory data comparison more challenging. Such variability undermines reproducibility and compromises the reliability of long-term proteomics and metabolomics studies conducted with LC-MS systems.
Advantages
✅ Ultra-High Purity Optimized for Mass Spectrometry
Acetonitrile, LC-MS Grade from MtoZ Biolabs is produced using advanced purification technologies and stringent multi-level quality control to ensure exceptionally low UV absorbance background, minimal non-volatile residues, and ultra-low metal ion content.
