Plug & Play Nitrogen for LC/MS
The Vici DBS Mistral Evo is a self- contained nitrogen generator that produces LC/MS grade nitrogen with pressure up to 8 bar. It produces nitrogen by utilising a combination of compressors, filtration, and Carbon Molecular Sieve (CMS) technologies. High and low pressure compressors filtered by high efficiency coalescing filters remove all contaminants down to 0.01 micron. CMS subsequently separate the clean air into a concentrated nitrogen stream and oxygen enriched permeate stream, which is vented from the system.
The combination of these technologies produces a continuous on-demand supply of pure nitrogen. Typical applications include LC/MS/MS nebuliser gases for APCI and ESI, ELSD, Turbo Vaps and chemical solvent evaporation. The Mistral Evo has been tried and tested by all the major LC/MS manufactures.
The unique combination of the dual compressor generator ensures that the Mistral Evo has several unique technical advantages over all other existing LC/MS Nitrogen Generators. Nitrogen is produced at low
pressure and then compressed to 8 bar resulting in longer compressor life.
The compressor life is guaranteed under the Vici DBS warranty for 8,000 continuous running hours, the longest currently available on the market For additional information and product support please contact Vici AG or your local Vici DBS distributor.
High Quality Solvents for Analytical and Preparative Separations Available
Honeywell Research Chemicals provides a wide range of high quality solvents under the Riedel-de Haën™ portfolio including more than 250 Chromasolv™ high-purity solvents. Chromasolv product lines deliver superior purity, stability, and lot-to-lot consistency, making them ideal for a variety of analytical and preparative separations utilising UHPLC, LC-MS, HPLC, GC and spectrophometric analysis. Chromasolv products have been custom designed to meet the requirements of each of the specific analytical methods, and are suitable for use in a diverse array of industries. Product specifications are achieved through careful material selection and processing along with stringent internal quality control systems. Honeywell’s approach to high purity products, reliability and environmental considerations is reflected by its ISO 9001 and RC 14001® certifications. Consistently meeting the requirements demanded by these global standards for quality management and environmental management demonstrates an uncompromising commitment to excellence in both areas. Chromasolv LC-MS solvents are designed specifically with low content of alkaline impurities such as calcium, magnesium, potassium, and sodium, which can interfere in the analysis by forming artifacts with the analyte. Chromasolv Plus, the multipurpose version, is tested for suitability in HPLC with gradient analysis, spectrophotometry, environmental testing, and some LC-MS applications. Chromasolv Gradient solvents provide added testing for suitability in HPLC with gradient analysis and spectrophotometry, and eliminate any impurity peaks which could be caused by the solvent rather than by the compound being tested - solvent impurity peaks are less than 0.005 absorbent units. Chromasolv for HPLC instrumentation and organic synthesis applications are glass distilled, submicron filtered and undergo rigorous specification testing to provide you with lot-to-lot consistency.
