Description

General description

LiChrosolv^® solvents have high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level. This makes them ideal for reproducible separations.

Application

Solvent for chromatography applications including:

• analysis of food products according to united states pharmacopeia (USP) methods
• HPLC determination of foodstuffs
• extraction of lactone flavors from fatty acid feedstocks
• vitamin A analysis of fortified food matrices using UHPLC
• Soxhlet extraction of plant materials for chromatographic separation
• quantification of fat-soluble vitamins by HPLC-MS
• detection of synthetic cannabinoids (SC) in e-liquids used in electronic cigarettes
• analysis of SC in blood, urine and herbal blend samples

Features and Benefits

• packaged in glass bottles
• offers high resolution, sensitivity and optimized peak baseline separation
