High-Resolution, Ultra-Clean Solvents for UHPLC-MS and LC-MS/MS Applications

Aladdin Scientific’s UHPLC-MS Grade solvents and reagents are meticulously refined for use in ultra-high-performance liquid chromatography (UHPLC) systems coupled with mass spectrometry (MS) detection. These products are engineered to deliver exceptionally low background noise, high ionization efficiency, and minimal metal or particulate contamination, enabling reliable quantification of analytes at trace or ultra-trace levels.

Key Features

· Ultra-Low UV and MS Background
Spectrally clean at 190–700 nm and background-free in full scan MS modes. Optimized for use in electrospray ionization (ESI) and APCI detection systems.

· Filtered to 0.1–0.2 µm
Prevents clogging in UHPLC columns and minimizes system downtime.

· MS-Compatible Formulations
Free of non-volatile buffers, plasticizers, and metal ions. Designed for use in sensitive MS workflows such as targeted quantitation, untargeted metabolomics, and multi-omics profiling.

· Batch-Tested for UHPLC-MS Suitability
Every lot is tested for critical parameters including UV absorbance, particle count, and MS background noise. Certificate of Analysis (CoA) available with full spectral profile.

Typical Applications

· Ultra-fast and high-resolution separations with UHPLC

· Quantitative and qualitative LC-MS/MS analysis

· Biomarker discovery, drug metabolism studies, and proteomics

· Bioanalytical method development under GLP/GMP settings

· Trace impurity profiling in pharmaceuticals and food safety testing
